A 2026 Supreme Court judgment has changed the legal test for what counts as a deprivation of liberty, and the change matters well beyond lawyers and care managers. It affects health and social-care staff, families, unpaid carers and organisations supporting people who may lack capacity to consent to where they live or how their care is arranged.
The Department of Health and Social Care update, revised on 22 September 2026, says the Supreme Court judgment was published on 2 June 2026, applies with immediate effect and has implications across the UK. The guidance also stresses that care planning should remain centred on the Mental Capacity Act framework and on the wellbeing of the person receiving care.
For families, the practical question is simple: could the new legal position change how restrictions on a relative’s movement, residence or care arrangements are understood? The answer can be yes, but the details depend on the person’s circumstances. This is not an area where a checklist alone can replace professional assessment.
What “deprivation of liberty” means in care
In health and social care, deprivation of liberty is a legal concept linked to Article 5 of the European Convention on Human Rights. It can arise when a person who lacks capacity to consent to their care or residence is subject to restrictions serious enough to amount to a deprivation of liberty.
That does not mean that every restriction is unlawful. Restrictions may sometimes be necessary to keep a person safe. The legal question is whether the arrangements amount to a deprivation of liberty and, if so, whether the right safeguards and authorisation process are in place.
Examples can include close supervision, limits on leaving a setting, continuous control over movement or care arrangements, or circumstances in which a person would not be free to leave. The exact legal analysis is fact-sensitive, which is why families should be cautious about trying to make a definitive judgment from one feature alone.
What changed in 2026
The Supreme Court’s June 2026 judgment clarified the definition used when deciding whether arrangements amount to a deprivation of liberty. DHSC’s September update is intended to help services, carers and organisations understand the implications while further interim guidance is developed.
One important point in the official update is that the ruling applies immediately. That means organisations should not wait for a completely rewritten code of practice before considering whether their current policies and individual care arrangements need review.
DHSC also notes that the existing Deprivation of Liberty Safeguards code of practice dates from 2008 and therefore does not fully reflect later case law, including the 2026 judgment. Some parts may still be useful, but they should not be treated as a complete statement of the current legal position.
What this means for family carers
Family carers are not expected to become legal experts. What they can do is notice the practical reality of someone’s care and ask informed questions.
If your relative lacks capacity to consent to their accommodation or care arrangements, consider what the arrangements actually involve. Are they continuously supervised? Can they leave if they want to? Are doors locked or exits controlled? Are there restrictions on movement that go beyond ordinary care? Have those restrictions increased recently?
The answer to one of those questions does not automatically mean there is a deprivation of liberty. But if the arrangements are highly restrictive, it is reasonable to ask the care provider, social worker, hospital team or other responsible service what legal framework authorises them.
Our Family Carers & Home Recovery guide explains how to keep useful records, prepare questions for professionals and track changes in a person’s care plan without taking on responsibilities that belong to clinical or legal professionals.
Capacity and best interests still matter
The 2026 judgment does not remove the importance of mental-capacity assessment or best-interests decision-making. A person should not be treated as lacking capacity simply because they make an unusual or unwise decision. Capacity is decision-specific and time-specific, and the Mental Capacity Act requires people to be supported to make their own decisions where possible.
Where a person does lack capacity for a particular decision, any decision made on their behalf should be in their best interests and should consider less restrictive alternatives.
That makes documentation important. Families should be able to understand what decision was made, why the person was considered to lack capacity for that decision, what options were considered and why the chosen approach was regarded as necessary and proportionate.
What care homes and hospitals may need to review
Care providers and hospitals may need to revisit policies, staff guidance and individual cases where restrictive arrangements are in place. The official update specifically addresses health and social-care staff, people caring for individuals who may be deprived of liberty, and staff responsible for organisational policies and procedures.
For a family, a review should not be treated as a paperwork exercise. The practical purpose is to ensure that restrictions are lawful, justified and no greater than necessary.
If a person’s circumstances have changed, the restrictions themselves may also need to change. DHSC notes that within existing DoLS authorisations, restrictions can be reduced when they are no longer required without waiting for a new authorisation simply to make the arrangements less restrictive.
Questions families can ask
When care feels unusually restrictive, useful questions include:
- What restrictions are currently in place, and why?
- Has the person’s capacity been assessed for the relevant decision?
- What less restrictive options were considered?
- What legal authority supports the current arrangements?
- When will the restrictions be reviewed?
- What should the family do if they believe circumstances have changed?
These questions are not accusations. They are a reasonable way to understand a care plan that affects a person’s liberty and day-to-day life.
When to ask for more help
If you cannot get a clear explanation from a care provider, hospital or local authority, ask who is responsible for the relevant mental-capacity and safeguarding decisions. Depending on the setting, that may be a social worker, safeguarding lead, DoLS team, clinician or other senior professional.
Where there is a serious dispute about a person’s liberty, residence, contact with family or major care restrictions, specialist legal advice may be appropriate. Advocacy services can also be important, especially where the person has difficulty expressing their wishes or there is no suitable family member to represent them.
Our Healthcare Navigation guide can help families prepare a clear chronology and questions before contacting services, which is particularly useful when several organisations are involved.
What remains uncertain
DHSC has said that additional interim guidance will be published and that practical case studies are being developed with stakeholder organisations and charities. That means some operational questions may become clearer as further guidance is released.
Families should therefore be careful with social-media explanations that claim the judgment means all restrictions are now lawful, or that all existing authorisations are invalid. Neither sweeping conclusion reflects the careful, case-specific approach described in the government update.
The bottom line
The 2026 Supreme Court judgment changes an important part of the legal framework around deprivation of liberty. For carers and families, the main practical consequence is that restrictive care arrangements may need to be looked at again under the clarified definition.
You do not need to decide the legal issue yourself. What matters is knowing enough to ask whether the person’s capacity has been properly considered, whether restrictions are necessary and proportionate, whether less restrictive options exist and whether the right safeguards are in place.
How this may affect reviews, care plans and safeguarding
The legal change also matters when care plans are reviewed. A care arrangement that was previously described as routine supervision may need closer examination if, in practice, the person is under continuous control and is not free to leave. Equally, a plan that was once highly restrictive may no longer need the same restrictions if the person’s condition, environment or support has changed.
That makes regular review important. Restrictions should not continue simply because they have always been written into a care plan. Professionals should be able to explain what risk each restriction is addressing, why it remains necessary and whether a less restrictive option would achieve the same aim.
Safeguarding concerns can overlap with deprivation-of-liberty questions, but they are not identical. If a family member believes restrictions are being used for convenience, punishment, staffing shortages or reasons unrelated to the person’s needs, that deserves separate attention. Concerns about neglect, abuse or unsafe care should be raised through the appropriate safeguarding route as well as through the care-planning process.
What good communication should look like
Families should not be expected to decode legal terminology without explanation. A good conversation should tell you what decision is being made, what capacity assessment has been completed, what restrictions are in place, which legal safeguard is being relied on and when the arrangements will be reviewed.
If the person can express wishes, feelings or preferences, those should be recorded even if they do not have capacity to make the final decision. A best-interests process should not erase the person’s own voice. Their history, routines, relationships and known preferences remain relevant.
Where several organisations are involved, ask who has responsibility for coordinating the plan. Hospitals, local authorities, care homes and community teams can each hold different pieces of information, and families can easily be left repeating the same history. A named contact and a written summary can reduce confusion.
Why the next DHSC guidance matters
Further interim guidance and case studies should help services translate the Supreme Court judgment into day-to-day practice. That will be particularly useful for borderline situations where care is intensive but the person also has meaningful freedom, or where restrictions vary across different parts of the day.
Until that guidance is published, families should be cautious about absolute claims. The safest approach is to focus on the individual circumstances, the actual restrictions being imposed, the person’s capacity and the legal safeguards in place.
This article is general information about health and social-care arrangements and does not constitute legal advice. If a specific person’s liberty or legal rights are in dispute, seek advice appropriate to the circumstances.
Families should keep a copy of any updated authorisation or review outcome with the person’s other important care documents so later teams can see what was decided and why.
