Beyond Mazur: Rights of Audience and the Continuing Problem of Unqualified Advocacy.

Whitestone Chambers’ Mina Heung, acting for British Airways Plc in Poulten & Others v British Airways Plc, 20 July 2026, successfully challenged the right of audience of an advocacy agent appearing in a small claims flight compensation case before District Judge Atkin at Uxbridge County Court.

The Court held that the advocate had not established a legal entitlement to appear. It also found that the challenge had been properly raised and awarded British Airways its costs arising out of the adjournment and determination of the preliminary issue.

The ruling provides a timely reminder that recent clarification of the law concerning the conduct of litigation has not resolved the separate and increasingly contentious question of who is entitled to conduct advocacy in the County Court.

The position after Mazur.

In Mazur v Charles Russell Speechlys LLP [2026] EWCA Civ 369, the Court of Appeal addressed the reserved legal activity of conducting litigation. It held that an unauthorised person may lawfully perform litigation tasks for and on behalf of an authorised individual, provided that the authorised individual retains responsibility and appropriate arrangements exist for management, supervision and control.

Mazur was an important decision, but it did not determine the separate question of rights of audience.

The Legal Services Act 2007 identifies the conduct of litigation and the exercise of a right of audience as distinct reserved legal activities. Authority to undertake litigation work under supervision does not therefore answer whether an individual is legally entitled to address the Court as an advocate.

That distinction was central to the issue before District Judge Atkin.

The representation structure.

The underlying claim concerned UK 261 statutory compensation following the cancellation of a flight.

The passengers had instructed a firm of solicitors to conduct their claim. That firm instructed a separate advocacy provider, which in turn instructed the individual who attended the hearing.

The structure was therefore:

Passengers → solicitors on the court record → advocacy provider → individual advocate

The individual did not possess an independent right of audience. His entitlement to conduct the hearing therefore depended upon establishing that he fell within an applicable exception.

The Court considered two possible routes: Practice Direction 27A and the exempt-person provisions within Schedule 3 to the Legal Services Act 2007.

Practice Direction 27A.

Practice Direction 27A defines a “lawyer”, for the purposes of representation on the small claims track, as including a barrister, solicitor or a legal executive “employed by a solicitor”, together with those otherwise authorised to act as litigators or advocates.

The advocate was described as having been “engaged” by the advocacy provider. The Court rejected the submission that the words “employed by a solicitor” should be interpreted as extending to any individual subcontracted or commercially engaged by a legal services business.

District Judge Atkin concluded that, had the provision been intended to encompass any person retained through such an arrangement, it could have been expressed in those broader terms.

The Practice Direction did not provide a general route by which an external advocacy agent could acquire a right of audience.

The limits of Halborg.

The alternative argument relied upon Schedule 3 paragraph 1(7) of the Legal Services Act 2007 and the decision in Halborg v Apple (UK) Ltd & Another [2022] (Unreported).
Halborg has frequently been relied upon for the proposition that advocacy may amount to “assisting in the conduct of litigation”. It is, however, a persuasive County Court decision rather than binding appellate authority, and it arose from a particular factual and professional structure.

In Halborg, the firm responsible for instructing and supervising the advocate was also, through its trading style, providing the litigation services in the proceedings. The Court’s conclusions were reached in the context of that integrated arrangement.

The structure before District Judge Atkin was materially different. The solicitors conducting the claim and the separate advocacy provider were distinct entities, with the individual advocate appearing at the end of a further chain of instruction.

The Court was not satisfied that the statutory conditions had been established merely by relying upon Halborg and asserting that the advocate was supervised.
Halborg did not confer an automatic right of audience. It did not operate as a gateway through which every individual instructed by an advocacy provider could pass.

A closer comparison: Vehicle Control Services v Langley.

The Defendant relied upon Vehicle Control Services Ltd v Langley [2026] EWCC 1 as a closer factual comparison.

Langley also concerned a layered structure in which the solicitors conducting the litigation instructed a separate advocacy provider, which then subcontracted an individual to attend the hearing.

DJ Pratt distinguished that arrangement from the traditional model of a managing clerk or legal executive genuinely working under the direction of the solicitor conducting the litigation. The Court held that advocacy alone could not make the exemption self-proving and that supervision by an advocacy agency which had taken no part in the litigation did not necessarily satisfy the statutory conditions.

District Judge Atkin considered the structure in Langley to be more closely analogous to the case before her.

The Court accepted that advocacy might, in an appropriate case, form part of assisting in the conduct of litigation. The difficulty was that the existence of advocacy could not, by itself, establish all the remaining elements of the statutory exemption.

The decision.

District Judge Atkin found that the right-of-audience challenge had been correctly raised.

The Court was not satisfied that the advocate fell within the relevant definition under Practice Direction 27A. Nor was it satisfied that the requirements of Schedule 3 paragraph 1(7) had been established.

The Judge emphasised that the responsibility rests upon the person seeking to exercise a right of audience. An individual without independent advocacy rights must attend court and be able to establish the legal basis upon which they seek to appear.

The ruling was expressly fact-specific. It did not establish that no advocacy agent could ever fall within the statutory exemption. It established that the exemption cannot be presumed merely because an individual has been instructed by a solicitor or through an advocacy provider.

The Defendant was awarded its costs arising from the adjournment and of the preliminary issue.

Why the issue matters.

Rights of audience are not just a procedural formality.

An advocate appearing before the Court undertakes professional responsibilities to the Court, the client and the administration of justice. Barristers, solicitors and independently authorised advocates are subject to regulatory standards, professional discipline and insurance requirements.

The same entitlement cannot be created simply by applying a professional-sounding label or inserting a regulated firm somewhere within a chain of commercial instruction.

The point is particularly important in high-volume small claims litigation. A claimant may have instructed one business, while the individual ultimately conducting the hearing has been retained through several further layers and may have had no direct contact with the claimant.

The claimant nevertheless remains the party to the proceedings and may bear the consequences of the way the case is presented, including an adverse costs order.

Clarity about who is entitled to appear therefore protects not only the Court and the opposing party, but the litigant whose case is being conducted.

The need for authoritative guidance.

Mazur has now provided authoritative clarification concerning the delegation and supervision of litigation work. It should not, however, be treated as resolving the separate law governing advocacy.

The continuing divergence between County Court decisions such as Halborg and Langley demonstrates the need for binding appellate guidance on the application of Schedule 3 to modern advocacy-agency arrangements.

Until that guidance is available, courts are likely to continue examining these arrangements on their individual facts.

The central principle remains straightforward.

An individual without an independent right of audience does not acquire one merely because they have been instructed through solicitors or an advocacy provider.


Halborg is not a gateway. Rights of audience must be established, not assumed.

This article is based upon counsel’s contemporaneous note of an ex tempore judgment. An approved transcript is awaited.

Gulfstream G700’s 100 Speed Records: Why This Matters Beyond Speed Records

Whitestone Chambers friends at Gulfstream Aerospace recently announced that its G700 business jet had achieved both its 100th customer delivery and its 100th city-pair speed record, the headlines naturally focused on speed. The G700’s 100th record was set on a flight from Georgia to California, completed in just 4 hours and 36 minutes at an average cruise speed of Mach 0.91. Shortly afterwards, the same aircraft set another record flying from California to New Jersey. For context, Mach 0.91 is significantly faster than the cruising speed of most commercial airliners, placing the G700 among the fastest civilian aircraft currently in regular operation.

Yet the most interesting part of the story is not the speed record itself. Impressive as those numbers are, speed records are ultimately a marketing tool. They demonstrate performance, generate headlines, and help manufacturers distinguish their aircraft in a highly competitive market. The more revealing figure in Gulfstream’s announcement is arguably not 100 speed records, but 100 deliveries.

The G700 only entered service after receiving certification from the Federal Aviation Administration (FAA) in March 2024. Since then, Gulfstream has delivered 100 aircrafts, secured approvals in over 20 countries, and seen more than 700 pilots obtain type ratings for the aircraft. For a highly sophisticated aircraft costing tens of millions of dollars, that is a remarkable pace of adoption.

What makes this significant is the amount of work that takes place behind the scenes before an aircraft can reach that point. When a new aircraft enters service, manufacturers are not simply selling a product. They are introducing an entirely new aircraft type into a highly regulated global system. Regulators must be satisfied that the aircraft is safe. Pilots must undergo specialised training. Maintenance programmes must be developed and approved. Operators must update procedures and manuals. Insurers have to assess risk. National aviation authorities must determine whether they will recognise or validate the original certification.

By the time the 100th G700 was delivered, an enormous amount of regulatory coordination had already taken place. Modern aviation law depends on a level of international cooperation such as the International Civil Aviation Organisation (ICAO) who define the standards and recommended practices that govern aviation safety, security, efficiency and environmental protection across 193 member states. Imagine if every country required Gulfstream to repeat the entire certification process from the beginning before permitting the G700 to operate within its airspace. Aircraft manufacturers would face years of additional testing, operators would encounter significant delays, and international aviation would become vastly more expensive and inefficient.

Instead, aviation regulators operate within a framework built on cooperation and mutual confidence. When a trusted authority such as the FAA certifies an aircraft, other regulators frequently rely upon that work when considering their own approvals. While additional reviews may still be required, the system avoids unnecessary duplication while maintaining safety oversight.

The G700’s rapid acceptance across multiple jurisdictions is therefore not simply a commercial success story. It is also evidence that this international regulatory framework continues to function effectively in an era of increasingly advanced aircraft. The aircraft also highlights a broader trend in aviation regulation. Modern business jets are becoming more technologically sophisticated, and as aircraft evolve, regulators face the challenge of ensuring safety without stifling innovation.

Aviation regulation has gradually shifted from a prescriptive regulatory framework to a performance-based approach, with regulators increasingly focusing on whether manufacturers can demonstrate that an aircraft achieves the required level of safety. Rather than prescribing a single design solution, they ask manufacturers to demonstrate that the aircraft meets the required level of safety. The G700 is an example of how that approach works in practice. Its certification demonstrates that existing regulatory frameworks are capable of accommodating new technologies while preserving the high safety standards upon which aviation depends.

Looking ahead, the most significant legal debates surrounding aircraft such as the G700 may centre on environmental regulation. Critics argue that private jets generate disproportionately high emissions per passenger, making them an increasingly visible target in discussions about climate policy. Supporters, meanwhile, point to the economic value they create by facilitating investment, international business activity, and connectivity to locations that may not be well served by scheduled airline services.

The G700 sits squarely within this debate. On the one hand, it represents technological progress. Compared to many older business jets, it is more fuel-efficient, incorporates modern engine technology, and is capable of flying longer distances with greater efficiency. If operators replace older aircraft with newer models such as the G700, emissions can be reduced on a per-flight basis. However, critics question whether efficiency improvements alone are enough. If the broader policy objective is to reduce aviation’s environmental footprint, the debate shifts from how aircraft are operated to whether certain types of flying should be encouraged at all. In that sense, the discussion becomes less about technology and more about public policy.

This presents regulators with a difficult challenge. Should aviation law focus on accelerating fleet modernisation and encouraging the adoption of cleaner aircraft? Or should it impose measures designed to discourage certain categories of air travel altogether?

The answer is likely to influence a wide range of regulatory developments, including sustainable aviation fuel mandates, emissions trading schemes, carbon taxation, environmental reporting requirements, etc. As environmental regulation becomes a larger part of aviation law, the legal questions surrounding aircraft such as the G700 may ultimately have to do with how society chooses to balance innovation, economic activity, and climate objectives.

Viewed in that context, Gulfstream’s latest announcement highlights the commercial success of one of the world’s most advanced business jets, but also offers a glimpse into the legal, regulatory, and environmental challenges that are likely to shape the next chapter of aviation. Modern aviation may no longer be defined solely by technological capability, but by how that capability fits within an increasingly complex regulatory landscape.

Ground Breaking Legal Reform

Baroness Carr, the Lady Chief Justice of England and Wales, has recently announced significant reforms to the structure of the High Court. From October of this year, the Chancery Division – the court that typically deals with commercial work – will be replaced by a new Business and Property Division, bringing many of the courts responsible for commercial and business disputes under one “roof”.

Out with the old…

The reform marks a bittersweet end to my beloved Chancery Division. It’s where as a young barrister I wanted to practice and I have been lucky enough to do so my entire career. The Chancery Division’s long history: with its early roots dating back to the Court of Chancery of the fourteenth century and the King’s Chancery several centuries earlier: make it one of the oldest institutions in the English legal system.

Critics of the previous structure have long argued that the division of commercial work between the Chancery Division and the King’s Bench Division was increasingly artificial. Despite handling similar types of high-value business disputes, courts such as the Commercial Court and Technology and Construction Court remained administratively separate from the Business and Property Courts. This may not accurately reflect the requirements of modern litigation – where disputes often span multiple areas of law and require specialist expertise drawn from different jurisdictions.

“Some might say that our three existing High Court Divisions no longer represent the work we actually do… Perhaps we should think about whether judicial leadership and the High Court Divisions should not more accurately reflect the types of work that are actually being done by our courts in 2025.” (Baroness Carr, Dec 2025)

…In with the new?

Under the new structure my former mini pupil master, Sir Colin Birss, currently Chancellor of the High Court, will become President of the Business and Property Division – headquartered in the Rolls Building in London, and continuing to operate from regional centres in Birmingham, Bristol, Cardiff, Leeds, Liverpool, Manchester, and Newcastle. 

In addition to the specialist courts already administered within the Chancery Division, he will assume responsibility for three courts that have historically sat within the King’s Bench Division: the Commercial Court, the Technology and Construction Court and the Admiralty Court. These courts will join the existing Business and Property Courts jurisdictions, including the Business List, Financial List, Competition List, Insolvency and Companies List, Intellectual Property List, Property, Trusts and Probate List and Revenue List.

Bringing these specialist jurisdictions together under a single division is intended to improve efficiency and make judicial deployment more flexible, enabling cases to be assigned more easily to judges with the most appropriate expertise. Such a single division had been proposed at the time of the CPR being developed in 1998 but was not followed through.

The government has welcomed the changes. In a statement to Parliament, Justice Secretary David Lammy said the reform would strengthen the international profile of the courts, improve accessibility for domestic and overseas users and provide a clearer system of judicial governance through a single point of leadership. The planned reforms come against the backdrop of a wider push by the judiciary for greater transparency in England’s courts, priorities set out by Carr.

The changes will be implemented through an Order in Council, accompanied by amendments to the Civil Procedure Rules and related practice directions.

Ch.D it’s been memorable.

U.S LIKELY TO MISS 2030 SAF TARGET – WSU STUDY FINDS

A study by Washington State University, (“WSU”), has found that the US is unlikely to realise its 2030 target for Sustainable Aviation Fuel, (“SAF”). Even under an optimistic assessment, the US is likely to produce 2.1 billion gallons of SAF, which falls short of the federal goal of 3 billion gallons per year by 2030. The domestic production is expanding, but will nevertheless be insufficient to meet the target without additional support and investment.

SAF facilitates the reduction of carbon emissions in the aviation industry. Although planes using SAF will burn an equivalent amount of carbon dioxide compared to those using normal jet fuel, the net carbon emission is lower in the former by virtue of SAF’s production process. Depending on the method of production, SAF has the capacity to reduce lifecycle greenhouse gas emissions by around 80 per cent. The most prominent form of SAF, as per the study, is Hydroprocessed Esters and Fatty Acids (“HEFA”), which are produced from oils and greases, such as cooking oil.

Unlike cars, which can be electrified, long-haul commercial flights cannot adopt such technology due to additional costs and/or technological incapacity. SAF is currently the most suitable means to reduce emissions since it requires minimal additional infrastructure. SAF can be blended with normal jet fuel.

The WSU-led study reviewed the relevant publicly announced projects in the US. One of the primary hurdles highlighted by the study is the non-implementation of projects; projects are announced, but not always carried out. To this effect, the study discusses the ‘implementation ratio’ to evaluate the ratio of projects which are announced versus those that are actually realised. Only about half of the announcements have led to operational facilities until now.

There are various reasons behind this announcement and implementation gap. One reason is the shortage of raw material to produce HEFA, i.e. used cooking oil. The demand for cooking oil has surpassed the present supply. A second connected reason is the commercial viability of SAF. Even if cooking oil is available to produce SAF, it might be more economical and commercially attractive for producers to use it to produce renewable diesel for cars, which is more profitable in light of the US policies and the current market given the Middle East conflict.

In the UK, the SAF target was missed in 2025. The mandatory target was for SAF to account for 2 per cent of the aviation fuel supply, but only 1.6 per cent was actually SAF. Although these figures are provisional, as per the Department for Transport. The target is 10 per cent by 2030 which now looks highly optimistic unless government action is taken.

The Rising Cost of Artificial Intelligence

Artificial Intelligence (AI) has transformed the technology sector at a remarkable speed over the past few years. What once appeared to be an experimental innovation, has quickly evolved into a mainstream tool used across almost every part of society.

From students and freelancers to professional services firms, AI has become embedded in everyday workflows, often faster than the broader public debate about its long-term consequences has been able to keep pace.

The appeal of AI is obvious. With tools like ChatGPT, Claude, Gemini, GitHub Copilot and many more such tools, tasks that would once have required hours of human effort can now be completed in seconds and minutes. AI systems are remarkably efficient at drafting documents, creating presentations, analysing data and automating tedious administrative tasks. Although this has driven lower operational costs and higher productivity for organisations, this quick uptake of AI has also raised serious concerns. More and more people are finding themselves without employment.[i] Why? Because organisations may view the use of AI as cheaper than paying the full salary of an individual, or so it seemed at first.

Over the past few months, AI businesses have been providing consumers with access to increasingly powerful AI tools at remarkably low costs. Advanced services have been made available to users for as little as $20 a month.[ii] These premium tools now do far more than generate basic text responses. With the help of AI agents that can perform complicated and time-consuming tasks, the advanced versions can now create apps from prompts, edit and design websites, automate workflows and even generate high-resolution images.

However, the period of cheap, flat-rate AI subscriptions may not be sustainable according to the recent developments.[iii] As reported by PCWorld, Microsoft-owned GitHub appears to be one of the first major AI providers to publicly abandon flat-rate subscription models. In response to growing concerns about the true cost of advanced AI services, the company is reportedly moving its Copilot AI offerings toward more costly usage-based pricing structures.[iv] The main issue is that large amounts of processing power are required for more powerful and sophisticated AI systems. Traditional AI chat features are relatively modest in comparison with the capabilities now being offered by newer tools. These systems are no longer limited to producing basic text outputs or responding to prompts; they are increasingly capable of generating software, carrying out multi-steps tasks, providing accurate advice and editing documents with little to no human supervision.[v] These functions have drastically raised operating costs and put significantly greater strain on the computing infrastructure. As a result, there is a gap between user expectations and economic reality when such services are offered at low fixed rates.

While AI service providers continue to bear the enormous infrastructure costs necessary to maintain those systems[vi], consumers have grown accustomed to having access to remarkably powerful AI capabilities at comparatively low prices. Anthropic, the company behind Claude AI, has mentioned that the purpose of its tools was primarily conversational and that certain newer functions were never intended to be supported by its current subscription models. It is reportedly experimenting with removing Claude Code from its Pro plan and adjusting Pro and Max users’ use limiting in an effort to discover a combination that makes those plans financially viable.

With these ongoing rises in subscription prices, it is hard to imagine that ChatGPT Plus and Pro will not eventually follow suit, even though OpenAI has so far signalled confidence in maintaining its flat-rate plans.[vii]

Ultimately, the market may be approaching a pricing correction. The true cost of advanced AI is likely to become clearer as providers seek business models that reflect the computational and infrastructure demands of these tools. What users currently access for $20 or $100 per month may, in time, cost significantly more particularly for business and enterprise users. Rather than signalling the end of AI’s appeal, this shift may simply mark the end of artificial cheap access to increasingly sophisticated technology. The magic of AI maybe fading…….

To Practice Law – What Now is Proper Supervision?

For a brief moment, it looked as though a huge part of everyday legal practice might suddenly become unlawful. That was the unsettling effect of the initial High Court’s decision in Mazur: a judgment which, called into question whether paralegals, trainees and legal executives could continue doing the work they have always done, issuing claims, progressing cases, and handling the mechanics of litigation, even under supervision.

The Court of Appeal’s recent decision in CILEX v Mazur has now restored a measure of stability, but it does more than simply reverse the earlier ruling. It offers a clearer articulation of how the law understands the conduct of litigation, and in doing so, brings it back into alignment with the realities of modern legal practice. At the centre of the case was the meaning of carrying on the conduct of litigation” as set out in the Legal Services Act 2007. The High Court approached that question by focusing closely on who performed particular tasks. The Court of Appeal reframed the issue. As it explained, “the words conduct of litigation refer to the tasks to be undertaken, whilst the words carry on refer to direction and control of, and responsibility for, those tasks.”

That distinction proves decisive. It shifts the emphasis away from the mechanics of legal work and towards responsibility for it. On that basis, the Court rejected the idea that unauthorised individuals are limited to a purely supportive role, holding that the distinction between assisting and conducting litigation under supervision was not correct. Instead, it confirmed that unauthorised persons may carry out tasks which fall within the conduct of litigation, provided they do so on behalf of an authorised individual who retains responsibility. In the Court’s words, it is not unlawful for an unauthorised person to act for and on behalf of an authorised individual so as to conduct litigation under their supervision,” so long as appropriate arrangements are in place.

The significance of that conclusion lies in its recognition of how legal services are actually delivered. Delegation is not a marginal feature of practice, but a central one. The Court acknowledged this directly, describing it as a widespread and well-regulated practice.” Across law firms, in-house teams and advice organisations, litigation is conducted through structured teams in which work is distributed across individuals with varying levels of qualification and experience. To characterise that model as unlawful would not only have been disruptive, but difficult to reconcile with the broader objectives of the statutory framework.

The decision also carries broader implications for the composition of the profession. The modern legal landscape is no longer defined solely by the traditional solicitor pathway. Alternative routes, including those offered through CILEX, have expanded access to legal careers and embedded a wider range of professionals within the delivery of legal services. Much of the work undertaken by those professionals sits precisely within the space that Mazur had rendered uncertain. By restoring the legality of supervised delegation, the Court of Appeal has, in effect, affirmed a more flexible and inclusive model of legal practice.

That said, the judgment is careful to emphasise that responsibility remains firmly anchored with the authorised individual. Delegation does not dilute accountability. The authorised person must retain control of the litigation, including responsibility to the client and to the court. Yet beyond that core principle, the Court deliberately avoided prescribing detailed rules. It acknowledged that the degree of appropriate control and supervision will always depend on the circumstances,” and declined to produce an exhaustive list of what falls within or outside the conduct of litigation.

This leaves a degree of flexibility at the margins. In many contexts, that flexibility will be both practical and necessary. However, in areas such as insolvency, where individuals may interact with non-authorised actors at an early stage and where significant decisions can be shaped before a formally authorised practitioner assumes control, the boundaries may be less clear. The Court’s emphasis on responsibility invites closer scrutiny of how, and at what point, that responsibility is meaningfully exercised in practice.

Looking ahead, the focus is likely to shift from the scope of delegation to the quality of supervision. Regulators, including the SRA, have already indicated that further guidance will be required, and firms will need to ensure that their internal structures reflect not only formal responsibility, but effective oversight. The question is no longer whether unauthorised staff can participate in litigation, that issue has now been resolved, but whether the systems within which they operate adequately support the retention of responsibility by authorised individuals.

The importance of Court of Appeal’s ruling lies in its recognition that legal practice is inherently collaborative. One way to understand what the Court of Appeal is recognising is to picture how a typical case actually moves through a modern legal team. A client’s matter might begin with a paralegal gathering documents, corresponding with the client, and preparing the first draft of a claim. A trainee or legal executive may then refine that draft, deal with procedural steps such as issuing proceedings or managing deadlines, and maintain day-to-day conduct of the file. Throughout, a supervising solicitor reviews key decisions, signs off on critical steps, and retains overall responsibility for the strategy and outcome of the case. No single individual does everything, yet the work progresses efficiently because each person contributes within a structured framework. What matters is that the supervising lawyer remains in control, not by performing every task personally, but by directing, checking and taking responsibility for the work as a whole. It is precisely this layered, collaborative model that the High Court’s decision placed under strain, and which the Court of Appeal has now, in effect, validated as both lawful and essential to the functioning of contemporary legal practice.

Ultimately, Mazur considers what the legal profession has already become. The Court of Appeal has recognised that litigation is no longer the work of a single, identifiable lawyer, but of teams operating within layered structures of responsibility. In doing so, it has preserved a system that is more efficient, more accessible, and more reflective of modern practice. But that recognition comes with a sharper challenge. If responsibility is the thread that holds this model together, it cannot be allowed to thin out as work is passed down the chain. The decision may have restored stability for now, but it also places the profession on notice: the legitimacy of this collaborative model will depend on whether supervision is real, accountability is felt, and responsibility remains more than a name attached to a file.

AI and the Mentorship Gap

Before one delves into the debate of whether Artificial Intelligence, (“AI”), simplifies the job of a lawyer – or potentially replaces us – one question is crucial to ask: what, exactly, is the job of a lawyer?

Before you reach for your phone and ask ChatGPT or its AI cousins, here is our view. There are two broad skills required in the legal profession; the first is good research and the second, sound judgement/prudence.

In its current state of development, AI has a good grasp on research, especially fast research. Judgement, comes with practical experience, not simply with the ability to process vast amounts of data quickly, and thus, it is still a skill to be developed by lawyers over time. Ultimately, good research has diminished significance if not coupled with legally sound strategy.

What this implies is that ‘tech-savvy’ Gen Z, albeit excellent at grasping and using AI tools to do their work faster, (or not do it at all?), still needs mentorship on how to use AI effectively. AI may produce an output for lawyers, but one must still have the ability to discern its accuracy and relevance.

Traditionally, the role of junior lawyers would involve repetitive tasks such as proof reading, first drafts, and contract reviewing – tasks which can take hours. We can see that AI makes it possible to complete this faster paving way for junior lawyers to take up more complex work. It should be viewed as an opportunity rather than a short-cut. Reports show that using AI has led to faster and better-quality work for the majority of lawyers.

However, according to LexisNexis’ report, ‘The Mentorship Gap’, more than 70 percent of the responders believe that lawyers are struggling to develop legal reasoning and argumentation skills in the age of AI. This may be because junior level work, although repetitive, builds the requisite discipline and judgement. This does not imply that the benefits of AI must be sidelined in order for skill development; new methods must be adopted to mentor AI-equipped lawyers. Indeed, only 2 percent of the responders believe that AI improves their learning. We agree.

The speed at which AI operates would be of great assistance at a senior level, but a junior lawyer requires skills beyond mere pace. AI, especially law centric and paid models, are certainly helpful in conducting research and administrative tasks, but lawyers still need to be mentored with respect to novel skills such as verification and source checking the outputs produced. Reports thus conclude that AI should be seen as a ‘thinking partner’.

For an aspiring advocate, using AI to stress-test arguments and find potential counterpoints before court, could be valuable without undermining skill development. Technological literacy, attention to detail and drafting effective prompts for AI tools are skills which will become increasingly important with time. Ironically, AI has also led to so called ‘reverse mentorship’ where junior employees are helping their seniors upskill in AI.

Ultimately, AI is not a replacement for research and legal judgement, it is better seen as a means of building those skills earlier in your career as a lawyer. The legal profession does not simply constitute sitting behind a screen and going through documents; a major part of it is client-facing and/or court-facing. Some skills are still built through experience, mentoring and good old human intelligence!

America’s Hottest March on Record: Anomaly or Warning?

March 2026 was not merely warmer than usual; it was historically and decisively so. Across the United States, temperatures did not just edge past previous records, they surpassed them by a margin so wide that it demands closer scrutiny. For the first time in recorded history, a single month exceeded the long-term average by more than 9 degrees Fahrenheit. That is not fluctuation. It is a signal. So the question becomes: when a record is broken so completely, is it still a record or is it evidence of a system that has fundamentally changed?

The data is striking. The previous benchmark for the warmest March, set in 2012, was eclipsed with ease. Ten states, including Arizona, California, Texas, and Colorado, recorded their hottest March on record. The American Southwest endured more than twelve days of record-shattering heat. Nationwide, nearly 19,800 daily temperature records were broken. Numbers of this scale do not suggest randomness, but acceleration. 

Yet temperature alone does not tell the full story. March was not only the warmest on record, it was also part of the driest January-through-March period observed in the contiguous United States since records began. Nearly 60 percent of the country is now experiencing drought conditions. The combination of heat and drought strain ecosystems, destabilize agriculture, and place extraordinary pressure on already fragile water systems. 

Consider Nebraska, where worsening drought conditions contributed to the largest wildfire in the state’s history: the Morrill Fire, which scorched more than 640,000 acres. Or perhaps take Florida, now enduring its worst drought in a quarter century, prompting water restrictions and heightening wildfire risk. These are manifestations of a broader pattern where extreme heat is intensifying existing vulnerabilities. 

This is most evident in the American West. The Colorado River, a critical water source for more than 40 million people across seven states, continues to face mounting stress. Reservoirs within the basin remain well below average levels. Lake Powell, the second-largest reservoir in the United States has already dropped more than ten feet this year alone, with projections indicating further decline in the months ahead.

This begs the question of what happens when a system designed for historical norms is confronted with conditions it was never built to withstand? Climate science offers an unsettling answer. According to the Fifth National Climate Assessment, human-driven climate change is increasing both the frequency and intensity of extreme heat events. Seasonal patterns are shifting, whereby winters are becoming shorter and milder while spring warmth is arriving earlier. Six of the ten most abnormally warm months in U.S. history have occurred within the past decade. The twelve-month period from April 2025 through March 2026 stands as the warmest on record for the continental United States. 

And yet, even as these records are being set, not only are the trends indicating a changing baseline, further escalation may already be underway. Forecasters are now closely monitoring the anticipated emergence of an El Niño event later this year, suggesting it could reach unusual strength. El Niño, a natural warming of Pacific Ocean surface temperatures, has long been known to elevate global temperatures. But in a world already warmed by greenhouse gas emissions, its effects may be amplified. 

Some scientists warn that a strong El Niño could push global temperatures to new heights into late 2026 and beyond. Others point to the possibility of longer-term shifts in climate patterns following particularly intense events; what was once considered temporary may, in effect, become the new normal.

This is where the distinction of weather and climate is important to establish. Weather is immediate, while climate is cumulative. A single hot month can be dismissed. A pattern of increasingly extreme months, occurring with greater frequency and intensity, cannot.

The implications extend well beyond temperature records. Water availability, agricultural stability, energy demand and disaster preparedness are influenced by these shifts. Legal and regulatory frameworks, many of which are grounded in historical data, may face increasing strain. 

Perhaps the most pressing question is not whether records will continue to be broken; the trajectory suggests they will. The more difficult question is how societies, institutions, and systems will respond when extremes cease to be exceptional. For now, the evidence points in a clear direction: the climate is changing and it is doing so at a pace that is no longer easy to ignore.

From Vindication to Exposure: Why the Gerry Adams Claim Collapsed

The recent discontinuance of civil proceedings against Gerry Adams in the High Court illustrates how procedural rules can shape litigation as decisively as statute or evidence. This is especially true in relation to costs, where a late-stage shift in risk can determine the outcome of a case regardless of its substantive merits.

Background of the case

The claimants were victims of IRA bombings, including the 1973 Old Bailey attack and later incidents in London Docklands and Manchester. Each sought nominal damages of £1, framing the case as a vindicatory exercise rather than a conventional claim for compensation.

Gerry Adams, former leader of Sinn Féin, has long denied IRA membership. The claimants alleged he bore personal responsibility for the attacks. The case proceeded to a two-week trial before Mr Justice Swift. Adams gave evidence over two days and was challenged on decades of material, including government documents and political statements. Counsel for Adams argued the claim rested on an “assortment of hearsay” and had been brought “several decades too late”.

Against that backdrop, the breadth of the evidence and the claimants’ aim of establishing responsibility for Troubles-era events raised a more fundamental procedural issue beyond a conventional civil claim.

Abuse of Process

It was in this context that the court intervened to consider whether the claim might amount to an abuse of process. Abuse of process is any use of litigation in a way that is “significantly different from the ordinary and proper use of the court process” The concern was not simply about the strength of the evidence, but about the function the proceedings were being asked to serve. Civil litigation is designed to determine defined disputes between parties on the basis of legally admissible evidence. It is not ordinarily a vehicle for a “collateral purpose” such as resolving broad questions of historical or political accountability.

By relying on extensive hearsay, historic allegations, and material not easily tested in the ordinary way, the claim risked inviting the court to conduct what was, in substance, a quasi-public inquiry into the Troubles. Although no final ruling on abuse of process was made, the judge’s decision to raise the issue at such a late stage fundamentally altered the nature of the litigation. What had been a question of liability became a question of whether the claim should have been brought at all – leading to potential costs implications for the claimants.

Costs Protection and the Risk of Adverse Costs

The claimants benefited from costs protection, most likely through qualified one-way costs shifting (QOCS), alongside any litigation funding arrangements in place. QOCS applies to claims for damages arising out of personal injury or death and operates to limit a claimant’s exposure to adverse costs. In practical terms, this means that, even if the claim fails, a defendant’s costs order is not enforceable beyond any damages recovered by the claimant. Here, where only nominal damages of £1 were sought, that protection would in effect operate as a near-complete shield against adverse costs liability.

However, that protection is not absolute. It can be disapplied where proceedings are struck out as an abuse of process. In such circumstances, the claimant loses the benefit of QOCS entirely, and any costs order becomes fully enforceable. If the court were to conclude that the proceedings constituted a misuse of its process, the claimants would therefore be exposed to the defendant’s costs in full.

As the claimants’ solicitors explained, the trial judge’s decision to raise this issue created “a real risk that the claimants… could face devastating personal liability for legal costs”. They added that the claimants had “no realistic choice” but to discontinue, given they were “faced with even a small risk of life-changing financial consequences”.

Conclusion

Ultimately, the case is a reminder that litigation is as much about risk management as it is about legal merits. Even a strongly motivated claim can become untenable if the cost position shifts. Here, once the possibility of losing costs protection arose, the position changed entirely. What began as a vindicatory claim became a question of exposure. Litigation strategy must be kept under constant review, not just considering the evidence, but in light of the evolving costs risk. Decisions to continue or discontinue are often driven less by the strength of the case than by the potential consequences of an adverse ruling.

A Legal Reset for AI Patents; The Turning Point for the AI and Software Patents Race in the UK

The boundaries of patent law are once again being tested by artificial intelligence. In a recent decision, the UK Intellectual Property Office (IPO) refused a patent application from AI music company DAACI for a system designed to automatically generate music based on an emotional brief. Despite the system’s ability to produce compositions with “audibly correct form,” the office concluded that the invention amounted to nothing more than a “program for a computer”, a category long excluded from patent protection under UK law.

The ruling highlights a growing legal tension: as generative AI systems increasingly blur the line between technical innovation and creative output, patent law is being forced to decide where software ends and invention begins.

At the centre of the dispute was a patent application filed by DAACI in March 2021 for a system designed to automatically generate musical compositions. The invention, described in patent GB 2605440A, aimed to create music that responds to an “emotional brief” provided by a user. In practice, the system would interpret narrative or emotional cues, such as tension, excitement, or melancholy and generate a composition intended to reflect those moods while maintaining what the company described as an “audibly correct form.”

The very nature of the invention; an AI system designed to automate the creative process, would become central to the legal challenge that followed. When the application came before the UK IPO, the key question was not whether the system could generate convincing music, but whether the underlying innovation amounted to a technical invention at all.

In assessing DAACI’s application, the UK IPO relied on the long-standing Aerotel framework for determining whether an invention falls within excluded subject matter such as a “computer program as such.” Under that approach, decision-makers first identify the invention’s contribution and then assess whether that contribution is technical in nature. Applying this reasoning, the hearing officer accepted that DAACI’s system contributed something new by automating musical composition in response to emotional prompts. However, he concluded that the problem being solved, producing aesthetically meaningful music, was ultimately creative rather than technical, meaning the invention remained within the exclusion.

However, just days after the DAACI decision was handed down, the Supreme Court ruled in Emotional Perception AI Ltd v Comptroller General of Patents that the Aerotel test should no longer be followed. Instead, UK law must align with the approach of the European Patent Office (EPO), particularly the Enlarged Board of Appeal’s decision in G1/19.

Under the new approach followed by the EPO, the first hurdle is relatively easy to clear. If an invention involves some form of technical system, such as software running on hardware, it will usually count as an “invention” in principle. But that does not mean it will receive a patent. The real test comes next, when examiners look closely at the invention’s features and ask a tougher question: which parts of this system actually represent a technical improvement? Only those technical elements are considered when deciding whether the invention is truly new and inventive compared to what already exists. This matters because, as AI systems become more sophisticated, whether an invention passes this test could determine which companies can claim ownership of the underlying technology, and ultimately shape who leads the next generation of AI-driven creativity.

Viewed through this updated lens, the reasoning in DAACI appears somewhat out of step with the direction of UK patent law. The new framework would focus more narrowly on whether the claimed system involved technical means and which elements of it possess genuine technical character. For AI-driven systems operating at the intersection of software and creativity, that shift could prove decisive.

The timing of the DAACI decision makes this tension particularly striking. The removal of the old Aerotel framework and the shift toward the EPO’s approach may make it easier for AI inventions to pass the first hurdle of patent eligibility. But that does not mean patents for generative AI will suddenly become commonplace. Instead, the battleground is likely to move deeper into the analysis, where companies must show that the technical machinery behind the AI, its architecture, training processes, or data processing methods, represents a genuine technological advance.

This shift could also change how AI developers approach patent strategy. Rather than emphasising the creative results produced by their systems, companies may increasingly frame their inventions around the technical processes that enable those results, for example; the way an algorithm processes input data, structures musical elements, or optimises the generation of compositions. In other words, the legal focus may move away from the music itself and toward the technical infrastructure that allows machines to create it.

If patents do begin to emerge around these kinds of AI systems, the effects could be far-reaching. AI models and training techniques could become some of the most valuable intellectual property in the technology sector, attracting investment but also raising the stakes in an already intense race to develop more powerful systems. At the same time, stronger patent protection could reshape competition, potentially allowing early movers to lock up key technological building blocks.

Ultimately, cases like DAACI reveal how uneasy the relationship between creativity and patent law has become. AI may be capable of composing music at the touch of a button, but the law still insists on asking the harder question: is the invention behind it is truly technical? And as AI grows more capable, that question is only going to get harder.
