What consideration has Welsh Government given to the recent Supreme Court ruling that removes the framework known as Cheshire West and the impact it will have on the rights of patients in Wales?

Answered by Deputy Minister for Social Care, Mental Health and Women’s Health | Answered on 23/06/2026

The law on mental capacity is not devolved in Wales, and the changes to the definition of a deprivation of liberty apply with immediate effect and across the UK.

We are considering the impact that the judgment by the Supreme Court  will have on the application of the Mental Capacity Act 2005 and deprivation of liberty in Wales. We will continue to work with the UK Government to fully understand the potentially significant implications of the judgment and to ensure consistency in the message to local health boards and local authorities in Wales.

These changes are likely to reduce significantly the number of cases that will legally amount to a deprivation of liberty. We recognise that a cautious approach will be needed whilst the law is clarified in this area.
