In February 2025, the Western Cape High Court handed down judgment in LPC v Swartz [2025] ZAWCHC 60. The matter concerned an attorney who had allowed a client’s delictual claim against the South African Police Service to prescribe. She had failed to issue summons timeously. When she discovered the error, she did not disclose it. Instead, she told the client the matter had settled, negotiated an amount the client would accept, and paid R398,000 from her personal funds in instalments. The file, when examined, contained a letter of demand and nothing more.

The court confirmed that the conduct was dishonest and that the concealment was a serious breach of professional obligations. What the court also recorded, at paragraph 51 of the judgment, was this: “panic and anxiety became the better of her and clouded her judgment.”

That sentence was not offered as an excuse. The court did not treat it as one. It was offered as a partial account of what had happened between the prescription error and the misrepresentation that followed. A practitioner’s judgment, under the pressure of a serious professional mistake, had been compromised by her own cognitive and emotional state.

The profession has a name for the prescription failure. It does not yet have an equivalent framework for the conditions that may precede it, or for the state of judgment that follows.

The Claims Record

The Swartz matter is not an anomaly. The Legal Practitioners Indemnity Insurance Fund reported 299 professional negligence claims in 2023/2024, a 14 percent increase year on year. Over the preceding five years, 1,536 claims were notified, generating R332.7 million in paid damages and investigation costs.

A missed prescription period is not, in most cases, a complex intellectual failure. It is a failure of attention, diligence, and system management. Those are precisely the cognitive functions that research identifies as the first to degrade when professional load is sustained beyond manageable levels.

The LPIIF Prescription Alert system registered 21,382 matters in 2023/2024. Of those, 1,804 prescription dates were interrupted, meaning they would otherwise have been missed. The system exists because missed prescription is a known, recurring failure mode across the profession, across practitioners of varying seniority and experience, across decades. The question the profession has not adequately answered is why that failure mode persists at this scale. The neuroscience offers a framework for beginning to answer it.

The Cognitive Mechanism

Cognitive risk, as it applies to legal practice, is the vulnerability created when the conditions of professional work degrade the cognitive function on which the quality of that work depends. The mechanism is documented and consistent.

Sustained cognitive load over time depletes the prefrontal cortex, the region of the brain responsible for judgment, reasoning, attention, and self-regulation. Research by neuroscientist Amy Arnsten at Yale has established that even moderate, sustained stress compromises prefrontal function in ways that are measurable and reproducible. This is not a matter of individual capacity or professional commitment. It is a biological response to conditions, and it applies to every practitioner who works under sustained load.

Daniel Kahneman’s work on cognitive bias under fatigue adds a further dimension. When cognitive resources are depleted, reasoning shifts toward faster, less rigorous processing. The practitioner may not register the shift. From the inside, the thinking feels careful. From the outside, and sometimes in the claims record, the result tells a different story.

None of this requires a dramatic precipitating event. The degradation is cumulative, quiet, and entirely foreseeable as a consequence of how legal practice is structured. A matter that does not surface at the right moment. A deadline tracked by a system, but not by the practitioner who is carrying twenty other files. A consultation at the end of a long week in which the advice given is reasonable, but not quite what it would have been on a different day, in different conditions.

The Risk Management Gap

The profession already has a name for this category of exposure: a risk management gap.

The legal profession manages legal risk with precision. Limitation periods are diarised. Conflicts are checked. Files are structured. Compliance frameworks operate at the firm level, the regulatory level, and the professional conduct level. These risks are treated as systemic because that is what they are. They are not personal failings. They are exposures that attach to the work, not to the character of the person doing it.

The profession has built no equivalent infrastructure for the cognitive conditions that may generate those very risks. The dominant response, when a practitioner misses a deadline or makes an error of diligence, is to locate the problem in the individual. The practitioner is told to manage their workload better, to be more organised, to build their capacity. The research does not support this framing as a complete account. Cognitive depletion under sustained professional load is, in significant part, a structural outcome of the conditions in which legal work is performed. It is foreseeable. It is measurable in its consequences. And it is currently unmanaged at the systemic level.

The Swartz case illustrates the chain at its most visible. A practitioner, a missed deadline, a state the court itself acknowledged had clouded her judgment, and a series of compounding decisions that ended in a High Court application. We cannot know whether cognitive overload contributed to the prescription error. We can observe that what followed it has the precise shape that cognitive science would predict: a practitioner under acute pressure, making decisions that compounded rather than corrected the original problem.

That pattern, at a far quieter scale, may be occurring across the profession every day. It simply does not produce a judgment on SAFLII.

What the Profession Needs to Measure

The profession manages what it measures and treats as risk. The prescription failure rate is measured, and the profession has built a system to interrupt it. What has not been built is any equivalent framework for the cognitive conditions that make that system necessary in the first place.

The question worth sitting with is not whether cognitive risk exists in the legal profession. The evidence suggests it does, and that its consequences are already in the claims record. The question is whether the profession is prepared to treat it with the same analytical rigour it applies to every other category of professional exposure.
