UK National Law
What is this right?
The Mental Health Act 1983 governs when someone can be detained in hospital ("sectioned") for assessment or treatment of a mental disorder. Key sections:
- Section 2: Detention for assessment — up to 28 days. Requires recommendations from 2 doctors and an application by an Approved Mental Health Professional (AMHP) or your nearest relative.
- Section 3: Detention for treatment — up to 6 months (renewable). Requires the same, plus a treatment plan.
- Section 136: Police power to take someone to a place of safety — up to 24 hours if they appear to be suffering from a mental disorder in a public place.
If you are detained, you have the right to:
- An Independent Mental Health Advocate (IMHA)
- Appeal to the Mental Health Tribunal
- Be treated in the least restrictive way
When does it apply?
- You can only be sectioned if you have a mental disorder of a nature or degree that warrants detention, and detention is necessary for your own health or safety or the protection of others.
- Voluntary patients ("informal patients") can leave hospital at any time — you cannot be prevented from leaving unless you are then formally sectioned.
- Your nearest relative has the right to apply for your discharge (though the responsible clinician can block this with a "barring certificate" in some cases).
- The Mental Health Act 2025 has received Royal Assent and will bring staged reforms — including replacing the nearest relative with a "nominated person" chosen by the patient, and strengthening patient choice.
What should you do?
- If you are sectioned, ask for an IMHA — they can help you understand your rights, attend meetings, and prepare for tribunal hearings.
- You have the right to appeal to the Mental Health Tribunal — for Section 2, within the first 14 days; for Section 3, within the first 6 months.
- You can also ask your nearest relative to apply for your discharge.
- If you're not detained, you have the same right to refuse treatment as anyone else (unless the Mental Capacity Act applies).

What should you NOT do?
- Don't assume sectioning means you lose all rights — you retain many rights, including the right to appeal, to an advocate, and to be treated with dignity.
- Don't leave a voluntary admission without telling staff — if they have concerns about your safety, they may attempt to section you.
- Don't refuse to engage with the tribunal process — it's your most powerful tool for challenging detention.

How Northern Ireland differs from UK national law
Northern Ireland has its own mental health law:
- The Mental Health (Northern Ireland) Order 1986 is the primary legislation (not the MHA 1983 used in England & Wales).
- Compulsory admission for assessment lasts up to 14 days (compared to 28 days under Section 2 in England).
- Compulsory admission for treatment lasts up to 6 months (similar to England).
- The Mental Capacity Act (Northern Ireland) 2016 is a groundbreaking law that fuses mental health and mental capacity law — the first legislation in the world to do so. It is being implemented in stages.
- The Regulation and Quality Improvement Authority (RQIA) safeguards patients' rights in NI.
