For more than a decade, the Cheshire West judgment has been a vital safeguard in identifying when a person is being deprived of their liberty and ensuring that appropriate legal protections are in place.
From 2nd June 2026, a new legal ruling will remove the Cheshire West framework, meaning the current approach to identifying and safeguarding deprivations of liberty will change.
What is Cheshire West?
“Cheshire West” refers to a landmark UK Supreme Court judgment from 2014, which clarified when a person is considered to be deprived of their liberty.
The judgment introduced a clear and consistent test (often referred to as the “acid test”), which asks whether a person who lacks capacity to consent to their care and support arrangements is subject to continuous supervision and control and is not free to leave.
If both conditions are met, the person is defined as being deprived of their liberty, and subsequently has access to the safeguards that accompany this, including representation, and right to review up to Court of Protection stage.
What has changed?
The new judgement states that the “acid test” introduced by Cheshire West was too simplistic and not correct in law. Instead, decisions should now consider a wider range of factors about a person’s individual situation.
It also suggests that, in some cases, a person who lacks capacity may still be seen as giving valid consent to their care arrangements, particularly if they are not objecting.
The judgement further states that people with profound disabilities cannot be considered deprived of their liberty in the same way, as their condition may limit their ability to experience this.
In practice, this is likely to mean that fewer people will be recognised in law as being deprived of their liberty. As a result, fewer people will automatically receive the legal safeguards, independent oversight, and advocacy that accompany a lawful Deprivation of Liberty.
Suzi Henderson, CEO of Cloverleaf Advocacy, said: “We are deeply concerned by today’s Supreme Court judgment overruling Cheshire West.
For more than a decade, Cheshire West has been a vital safeguard in helping identify when a person is being deprived of their liberty and ensuring that legal protections are triggered.
Today’s judgement marks a major shift away from that approach. We are extremely concerned by what we see as a serious regression in the safeguarding and upholding of basic human rights for people who are most at risk from systemic abuse, closed cultures, and restrictions on their lives.
We are particularly worried about the practical impact this may have on people with disabilities, autistic people, people with learning disabilities, people with dementia, people with mental ill health, and others who may be living with significant restrictions but who are currently at least able to challenge those arrangements through formal routes and safeguards.
Independent scrutiny, advocacy, and accessible routes to challenge restrictions are not optional extras. They are essential protections. History has shown, time and again, that where oversight is weakened, the risk of abuse, neglect, and harmful closed cultures increases.
We are calling for urgent national clarity about the implications of this judgement and for strong, rights-based safeguards to remain in place. Any future guidance or legal reform must protect people’s liberty, dignity, voice, and right to challenge restrictive arrangements.”
Cloverleaf Advocacy will continue to stand alongside people whose rights are at risk. We will also continue to work with partners across health, social care, and the advocacy sector to press for clarity, accountability, and stronger protections.
