For more than a decade, one of the most influential legal ideas in health and social care was captured in a simple phrase: “a gilded cage is still a cage.” That phrase came from the 2014 UK Supreme Court case known as Cheshire West, which reshaped how the law understood when a person is deprived of their liberty.
On 2 June 2026, the UK Supreme Court reversed that decision. This is an important development for families, care providers and professionals involved in supporting adults who may lack capacity to make decisions about their care arrangements.
The original Cheshire West case dealt with people who lacked the mental capacity to make decisions about their care – often individuals with dementia, severe learning disabilities, or serious mental illness.
The court introduced what became known as the “acid test.” Under this approach, a person was considered deprived of their liberty if:
Importantly, it didn’t matter whether the person seemed content or whether the care arrangement was in their best interests. If those conditions were met, legal safeguards had to apply.
This rule was simple, easy to apply, and far-reaching. It dramatically widened the number of people considered deprived of their liberty, leading to hundreds of thousands of formal safeguards being required each year.
In June 2026, the Supreme Court unanimously overturned Cheshire West. The Court decided the “acid test” was too rigid and overly simplistic.
Instead, the law now returns to a more flexible, “multifactorial” approach, meaning that professionals must look at the whole situation of the individual.
This includes:
Perhaps the most striking development is the recognition that a person who lacks formal legal capacity may still be able to express valid consent to their situation.
In simple terms: if someone appears happy, settled, and accepting of their care, this may count as meaningful consent and reduce the likelihood that the law sees their situation as a deprivation of liberty.
Supporters of the new approach say it is more realistic. They argue that the previous system was overly bureaucratic, labelling too many care arrangements as legal “detentions” and placing significant strain on services.
Critics, however, warn that the decision could weaken vital protections. Some commentators fear that fewer people will receive independent oversight of their care, increasing the risk that poor or restrictive arrangements go unnoticed.
At its heart, the debate is about balance:
The impact of this case is UK-wide because it is grounded in Article 5 of the European Convention on Human Rights (the right to liberty).
Scotland has always taken a slightly different legislative path than other parts of the UK.
Rather than adopting the same “Deprivation of Liberty Safeguards” (DoLS) system used in England and Wales, Scotland relies on a combination of:
These frameworks already place strong emphasis on taking account of the individual’s wishes and feelings, even where capacity is impaired.
In the 2026 case, the Mental Welfare Commission for Scotland intervened, arguing that people without full legal capacity may still be able to express meaningful views – and that those views should matter.
The Supreme Court explicitly drew on this Scottish perspective, suggesting that Scotland may, in some respects, have been ahead of the curve.
The Scottish Mental Health Law Review has been considering reform of mental health and capacity law for several years. A key theme of that review is the need to:
The new Supreme Court decision aligns with some of these aims – particularly its focus on personal autonomy and recognising individuals’ perspectives.
However, it also raises important questions:
The reversal of Cheshire West represents a profound shift. It moves the law away from a bright-line rule and towards a more nuanced, but potentially less predictable, approach.
For Scotland, the decision is both reassuring and challenging:
Ultimately, the question is not just legal but ethical: how do we respect the dignity and autonomy of people who may struggle to make decisions, while still protecting them from harm?
The answer will shape the future of mental health law across Scotland—and will determine whether the balance between care and liberty is struck in the right place.
