The Bottom Line
- DoLS applies when a person who lacks capacity is deprived of their liberty in a hospital or care home — authorisation is needed to make the deprivation lawful
- Cheshire West "acid test" (2014): a person is deprived of liberty if they are (1) under continuous supervision and control AND (2) not free to leave, AND (3) lack capacity to consent to these arrangements
- It does NOT matter if the person seems content, or if the arrangement is in their best interests — if the acid test is met, DoLS authorisation is required
- Current system: DoLS (MCA 2005, Schedule A1). Being replaced by Liberty Protection Safeguards (LPS) under the MCA Amendment Act 2019 — but LPS implementation has been repeatedly delayed
- Key roles: Managing Authority (hospital/care home) applies. Supervisory Body (local authority) authorises. Best Interests Assessor (BIA) assesses. Relevant Person's Representative (RPR) safeguards the person's interests
Overview
The Deprivation of Liberty Safeguards (DoLS) were introduced in 2009 as an amendment to the Mental Capacity Act 2005 (Schedule A1). They provide a legal framework for authorising the deprivation of liberty of a person who lacks capacity, when this is in their best interests and proportionate. Article 5 of the European Convention on Human Rights (right to liberty and security) prohibits deprivation of liberty without lawful authority. Following the Supreme Court ruling in Cheshire West (2014), which broadened the definition of deprivation of liberty, DoLS applications increased dramatically. The Liberty Protection Safeguards (LPS) were designed to replace DoLS with a streamlined system, but implementation has been repeatedly delayed and remains uncertain as of 2026.
Epidemiology
After the Cheshire West ruling in 2014, DoLS applications in England increased from approximately 11,000 per year to over 260,000 per year. Local authorities have been overwhelmed by the volume. Many applications face significant delays. The system was widely criticised as bureaucratic and inadequate, leading to the LPS reforms. The most common settings requiring DoLS are care homes (patients with dementia who cannot leave freely) and hospitals (patients on medical wards who are under continuous supervision and lack capacity to consent).
Key Concepts
Symptoms
Cheshire West acid test: (1) person lacks capacity to consent to their care arrangements, (2) person is under continuous supervision and control, AND (3) person is not free to leave — ALL THREE must be present
Common scenarios: patient with advanced dementia in a care home with locked doors; delirious patient on a medical ward with 1:1 nursing and bed rails; patient with learning disabilities in supported living with restricted movement
DoLS applies ONLY in hospitals and care homes. For other settings (supported living, domestic) → Court of Protection authorisation required
A DoLS authorisation can last up to 12 months (standard) or 7 days (urgent)
Signs
Being "content" or "compliant" does NOT mean there is no deprivation of liberty — Cheshire West was clear on this
DoLS and MHA are separate frameworks: MHA is for mental disorder treatment; DoLS is for care arrangements that amount to deprivation of liberty for people lacking capacity
If a person has capacity, they cannot be deprived of liberty under DoLS (MCA framework) — consider MHA if they have a mental disorder
Process
First-line
Identify possible deprivation of libertyApply the Cheshire West acid test. If all three criteria are met → DoLS application needed
Managing Authority appliesThe hospital or care home (Managing Authority) submits an application to the local authority (Supervisory Body) — both standard and urgent if needed
Second-line
6 assessments by the Supervisory BodyAge (≥18), Mental health (has mental disorder), Mental capacity (lacks capacity for the relevant decision), Best interests (deprivation is in best interests, proportionate, least restrictive), Eligibility (not ineligible due to MHA detention), No refusals (no valid ADRT or LPA refusal that conflicts)
Best Interests Assessor (BIA)Conducts the best interests assessment. Must consult the person, their family/carers, and any IMCA. Makes recommendation to Supervisory Body
Specialist
Relevant Person's Representative (RPR)Appointed to maintain contact with the person and ensure their rights are upheld. Usually a family member. Supported by an IMCA if no suitable person available
Court of ProtectionFor deprivation of liberty outside hospitals/care homes, or if the DoLS assessment is disputed
1
When to apply
- Whenever a patient who lacks capacity is under continuous supervision and control and not free to leave (acid test)
- Common triggers: locked doors, 1:1 nursing, bed rails, sedation for the purpose of compliance, consistent prevention of leaving
- Urgent authorisation: Managing Authority can grant for up to 7 days while awaiting standard authorisation
2
While awaiting authorisation
- Care should continue in the person's best interests
- Use the least restrictive option — can the same outcome be achieved with fewer restrictions?
- Document the restrictions, rationale, and review date
3
Review and challenge
- Standard authorisation lasts up to 12 months — must be reviewed if circumstances change
- The person (or their RPR) can challenge the authorisation in the Court of Protection at any time
- An IMCA can help the person or RPR exercise their right to challenge
4
Liberty Protection Safeguards (LPS) — future system
- Mental Capacity (Amendment) Act 2019 creates LPS to replace DoLS
- Key changes: Responsible Body (NHS trust/local authority) arranges authorisation. Extends to all settings (not just hospitals/care homes). Pre-authorisation review by an AMCP (Approved Mental Capacity Professional)
- Implementation has been repeatedly delayed — as of early 2026, DoLS remains the operative system
Complications
- Unlawful deprivation of liberty: If restrictions meeting the acid test are in place without DoLS authorisation → breach of Article 5 ECHR. The trust/care home may be liable for damages
- Delayed authorisation: Chronic backlogs in many local authorities, leaving patients without lawful authorisation for extended periods
- Excessive restriction: Using more restriction than necessary — must always seek the least restrictive option
UKMLA Exam Tips
- 1Cheshire West acid test: lacks capacity + under continuous supervision and control + not free to leave = deprivation of liberty
- 2Contentment is irrelevant — a smiling, compliant patient with dementia in a locked care home IS deprived of their liberty
- 3DoLS applies ONLY in hospitals and care homes. Other settings → Court of Protection
- 4Urgent DoLS = 7 days (Managing Authority grants). Standard DoLS = up to 12 months (Supervisory Body authorises after assessment)
- 5DoLS ≠ MHA. DoLS = MCA framework for care arrangements. MHA = compulsory treatment of mental disorder
- 6LPS will eventually replace DoLS but has been delayed repeatedly — exams may test either framework
- 76 assessments: age, mental health, mental capacity, best interests, eligibility, no refusals
