Psychiatric Negligence Claims in Scotland
There is a particular kind of silence around mental health care that does not exist anywhere else in medicine. If a surgeon operates on the wrong knee, the patient knows something has gone wrong and says so. If a psychiatrist misdiagnoses a patient for a decade, prescribes medication without the required monitoring, or discharges someone in crisis before it was safe to do so, the patient very often blames themselves, or blames the illness, or simply never realises that what happened to them had a name. Psychiatric negligence is one of the least discussed areas of medical negligence law in Scotland, and yet the harm it causes can be as profound as anything a scalpel can do.
This essay explains how these claims work under Scottish law: what has to be proved, the kinds of failures that give rise to claims, the position of patients who were detained, what happens when a family is claiming after a death, how compensation is assessed, and the time limits that apply. Everything here is specific to Scotland, because Scotland has its own negligence test, its own mental health legislation, its own courts and its own rules on time limits. Guidance written for England and Wales, of which there is a great deal online, will mislead a Scottish reader on several important points.
The Starting Point: Psychiatrists Are Doctors, and the Law Treats Them That Way
The first thing to establish is something many people genuinely do not know: you can bring a negligence claim in respect of psychiatric care on exactly the same legal footing as a claim about surgery, general practice or dentistry. A consultant psychiatrist, a community psychiatric nurse, a mental health team and a health board all owe their patients a duty of care. When that duty is breached and harm results, the law of Scotland provides a remedy.
The test for breach comes from a Scottish case decided in 1955, Hunter v Hanley, which remains the foundation of medical negligence law in Scotland today. The test asks whether the professional acted as no reasonably competent practitioner in that field, acting with ordinary skill and care, would have acted. That wording matters, because it sets a deliberately demanding standard. Medicine, and psychiatry in particular, involves judgement. Two competent psychiatrists can look at the same patient and reasonably reach different conclusions about diagnosis or treatment. Where a decision falls within the range that a responsible body of psychiatric opinion would support, there is no negligence, even if hindsight shows the decision led to a poor outcome.
What the test catches is care that falls outside that range altogether. Not the treatment that did not work, but the diagnosis no competent psychiatrist would have missed on the information available. Not the difficult judgement call, but the blood test that national guidance required and nobody ordered. The distinction between a bad outcome and negligent care runs through every one of these claims, and it is the question an independent expert psychiatrist is instructed to answer in each case.
Misdiagnosis: The Years That Go Missing
The most common thread in psychiatric negligence claims is diagnosis that went wrong and stayed wrong. Mental health conditions overlap in their symptoms, and an initial working diagnosis that later proves incorrect is not, by itself, negligent. The claims arise where the evidence pointing to the correct diagnosis was present, recorded and repeatedly not acted upon.
The classic example is bipolar disorder treated for years as depression. Antidepressants prescribed alone to a person with unrecognised bipolar disorder can trigger the very episodes of elevated mood that define the condition, and those episodes, once they appear in the notes, are precisely the signal a competent psychiatrist is trained to recognise. When a patient spends ten or twelve years cycling through antidepressants, with documented episodes that should have prompted a rethink, and the correct diagnosis is finally made by a new clinician reading the same file, the question for the expert is stark: on this record, at what point would a reasonably competent psychiatrist have reached the right answer? Every year between that point and the actual diagnosis is a year of the wrong treatment, and often a year of avoidable harm to work, relationships and health.
Similar patterns arise with other conditions: personality disorder diagnoses applied where the true picture was trauma-related, psychotic illness attributed to substance use without proper assessment, and physical conditions with psychiatric presentations, such as thyroid disease, never tested for at all.
Medication: Where the Standard Is Written Down
Some psychiatric medications are extraordinarily effective and unforgiving in equal measure, and for those drugs the standard of care is not a matter of professional debate. It is written down in national prescribing guidance, and the patient's records show whether it was followed.
Lithium is the leading example. It remains one of the most effective treatments in psychiatry for bipolar disorder, but the margin between a therapeutic dose and a toxic one is narrow, and levels in the blood can drift for reasons as ordinary as dehydration or a new interacting prescription. For that reason, patients on lithium must have their blood levels and their kidney and thyroid function checked at defined intervals. When that monitoring lapses and toxicity develops unnoticed, the consequences range from tremor and confusion to permanent kidney damage. A claim of that kind does not turn on fine questions of clinical judgement. It turns on dates: when the guidance said the tests were due, and when they were actually done.
Clozapine, used in treatment-resistant schizophrenia, carries its own mandatory blood monitoring regime because of the risk it poses to white blood cells. Failures there are equally clear-cut. Beyond monitoring, medication claims also arise from dangerous drug interactions that should have been checked, from doses continued long after they should have been reviewed, and from serious side effects that were never explained to the patient before treatment began.
That last category engages a distinct legal duty, and it comes from another Scottish case. In Montgomery v Lanarkshire Health Board, decided by the Supreme Court in 2015, the law of informed consent was restated for the whole United Kingdom. A doctor must take reasonable care to ensure the patient is aware of the material risks of a proposed treatment and of the reasonable alternatives, judged by what a reasonable person in that patient's position would want to know. In psychiatry, where long-term medication can carry risks such as significant weight gain, metabolic disease and movement disorders that may persist after the drug is stopped, the duty has real teeth. A patient who develops a known but never-mentioned complication, and who would have chosen differently had the risk been explained, may have a claim even where the prescribing decision itself was competent.
Risk, Observation and Discharge
The most serious psychiatric negligence claims concern failures to protect patients from harm at the times they were most vulnerable. Mental health services assess risk constantly: on admission, on changes in presentation, on leave from a ward and, above all, on discharge. The law does not demand that these assessments be right every time, because predicting human behaviour is not an exact science. It demands that they be carried out competently, that clear warning signs recorded in the notes be taken into account, and that decisions such as reducing observation levels or discharging a patient be made on the information actually available rather than in spite of it.
Claims in this category include patients discharged from hospital while known risk factors remained unaddressed and without adequate follow-up arranged, warning signs reported by families that were documented and not acted on, and observation regimes on wards that were not carried out as prescribed. Where such failures lead to a death that competent care would have prevented, the claim passes to the family, and Scottish law is specific about what that means.
Under the Damages (Scotland) Act 2011, close relatives of a person whose death was caused by negligence can claim compensation for their grief and the loss of the relationship, for the loss of financial support the person provided, and for funeral costs. Families in this position often say that compensation is not their primary motivation, and that is worth taking seriously: a civil claim is frequently the only process that compels full disclosure of the records and a reasoned answer to the question of what went wrong. A Fatal Accident Inquiry, where one is held, examines the circumstances of a death in the public interest, but it does not award compensation and it is not a substitute for a claim. The two can proceed alongside each other.
Detained Patients Have the Same Rights
A persistent and damaging myth deserves its own section: the belief that a person detained under mental health legislation somehow loses the right to complain about their care. The opposite is closer to the truth. Detention under the Mental Health (Care and Treatment) (Scotland) Act 2003 places a patient in the care of the state precisely because they are unwell, and the standard of care owed to them does not drop by a single degree. A detained patient is owed competent diagnosis, competent prescribing, competent monitoring and competent observation, and if anything the duty weighs more heavily, because a detained patient cannot seek care elsewhere.
Beyond the quality of treatment, the lawfulness of detention itself can found a claim. The 2003 Act sets out defined criteria and procedures for short-term and compulsory treatment orders, with safeguards including the Mental Health Tribunal for Scotland. Where detention is imposed without the statutory criteria being met, or is continued after it ceased to be justified, the person detained may have a claim in respect of the detention itself, separate from any question about the treatment they received.
Time Limits, and Why They Are More Generous Here Than People Assume
The general rule in Scotland comes from the Prescription and Limitation (Scotland) Act 1973: a personal injury claim, which includes psychiatric injury, must be brought within three years. Crucially, the three years run not from the date of the negligent care but from the claimant's date of knowledge, meaning the point at which they knew, or could reasonably have known, that they had suffered significant harm attributable to fault. In psychiatric cases that date is very often years after the events, because the realisation typically arrives only when a new clinician reviews the history and says, in terms, that things should have been done differently.
There is a further protection of particular importance in this field. Time generally does not run against a person during any period in which they lacked legal capacity. A patient who was too unwell, for a sustained period, to understand or act upon what had happened to them may find that the limitation clock only began when capacity returned. The courts also retain a discretion to allow claims outside the three-year period where the balance of fairness favours it. None of this should encourage delay, because records fade and witnesses move on, but it does mean that nobody should silently rule themselves out on timing without taking advice.
What Compensation Covers and How a Claim Actually Proceeds
Compensation in these claims has two parts. The first is pain and suffering compensation for the psychiatric injury itself, assessed with reference to the Judicial College Guidelines, which set brackets by severity: from modest awards where the harm was less severe and recovery was good, through moderate and moderately severe categories, up to six-figure awards where the injury is severe and permanent. Where negligent psychiatric care also caused physical harm, such as kidney damage from unmonitored lithium, that injury is valued in addition. The second part is financial loss: earnings lost during periods of avoidable illness, the cost of private treatment and therapy made necessary by the negligence, care provided by family members, and future losses where the effects continue.
The claim itself proceeds in a recognisable sequence. The full medical records are recovered and read closely, because these cases are won and lost in the notes. An independent expert, usually a consultant psychiatrist, reports on whether the care met the Hunter v Hanley standard, and a second expert may address what difference competent care would have made. Most claims resolve by negotiation with the health board or defence organisation; those that do not are litigated in the Sheriff Court or the Court of Session depending on value. Handled on a no win no fee basis, the process carries no financial risk to the patient, and making a claim has no effect on the person's entitlement to ongoing NHS care.
The Bottom Line
Psychiatric care in Scotland is held to the same legal standard as every other branch of medicine, and the patients it fails have the same rights as any other injured person. A poor outcome is not negligence, and the Hunter v Hanley test properly protects the difficult judgements psychiatry requires. But a diagnosis the records made obvious, a monitoring regime written in national guidance and never followed, a serious risk never explained, warning signs documented and ignored, or a discharge no competent clinician would have signed off are failures the law recognises, whether the patient was in the community, in hospital or detained under the 2003 Act. The time limit runs from knowledge rather than from the events, it can pause during incapacity, and families can claim where a preventable death has occurred. For anyone who suspects that what happened to them or to someone they love was more than bad luck, the records hold the answer, and finding out costs nothing.
