In England and Wales, the Mental Health Act 1983 (MHA 1983) provides the legal framework which governs decisions made concerning the care and treatment of those suffering from mental disorders, where they may pose a risk to themselves or others. The perspective of the patient and the care provider may conflict and can be a source of tension and challenge within mental health law. Through access to a mental health tribunal, patients are offered the apparatus to review and challenge their detention. With detention rates under the mental health legislation rising exponentially, this is having a knock-on effect upon tribunal application numbers. As there is a legal requirement to review all cases of individuals detained under the MHA 1983, understanding the key drivers for this increase in detention is essential in order to understand how to better manage both detention rates and the upsurge in tribunal caseloads. With the increase in overall activity, mental health tribunal workloads present significant practical challenges and has downstream cost implications.
