Mental capacity assessment for DoLS and deprivation of liberty
After AGNI on 2 June 2026, deprivation of liberty requires a multifactorial Article 5 assessment. MCA capacity for residence or care remains a separate question; compliance alone is not consent, and safeguards remain necessary where Article 5 is engaged.

04Abstract
After AGNI on 2 June 2026, deprivation of liberty requires a multifactorial Article 5 assessment. MCA capacity for residence or care remains a separate question; compliance alone is not consent, and safeguards remain necessary where Article 5 is engaged. This guide covers the relevant evidence, support, process and limits in England and Wales.
After AGNI on 2 June 2026, deprivation of liberty requires a multifactorial Article 5 assessment. MCA capacity for residence or care remains a separate question; compliance alone is not consent, and safeguards remain necessary where Article 5 is engaged.
06Direct answer
A residence or care assessment applies MCA sections 1–3 to that decision. Whether arrangements amount to deprivation of liberty is a distinct Article 5 question about objective confinement, valid consent and state responsibility. After AGNI, a person who lacks domestic-law capacity may nevertheless give valid Article 5 consent in the circumstances identified by the judgment. Do not infer it from compliance alone or where there is serious doubt.
07What AGNI changed and what it left
AGNI requires assessment of the person’s concrete situation, including the type, duration, effects and manner of restrictions. Supervision and freedom to leave remain relevant factors, but there is no universal acid test. Consider the person’s actual understanding, wishes and objections. The MCA framework and the need for safeguards where Article 5 is engaged remain; the judgment did not automatically end every authorisation.
08Where capacity assessment still does the work
Capacity determines whether the person can make the particular residence or care decision with support. If they cannot, consider the appropriate best-interests process and lawful authority. This evidence may also inform Article 5 analysis, but neither a capacity finding nor apparent happiness alone answers the liberty question.
09Identify the relevant information
For residence or care capacity, identify the actual options, support and foreseeable consequences. For Article 5, establish the concrete restrictions, their effects and the person’s understanding, wishes and objections. Explain the question each item of evidence answers rather than use one generic assessment for both.
10Gather evidence before drawing conclusions
Useful evidence may include care plans, DoLS paperwork, restrictions, residence arrangements, supervision needs, risk assessments, best interests records and evidence of the person’s wishes, objections and communication needs.
11Consider risk, pressure and vulnerability carefully
Risk factors should be recorded without being treated as shortcuts to incapacity. Relevant issues may include family conflict, urgency, financial pressure, inconsistent instructions, communication barriers, safeguarding concerns, dependency on others, or a history of cognitive impairment. The report should separate risk from the legal question of capacity.
12Make the reasoning easy to follow
Existing DoLS authorisations and court orders did not all end automatically. Review the actual authorisation, order, restrictions and consent position. Government guidance says responsible bodies should review existing arrangements in light of AGNI rather than assume the old label or authorisation answers the present legal question.
13How this links to Nellie Supports services
Current official guidance continues to use DoLS for qualifying adults aged 18 and over in hospitals and care homes and court routes in other settings. Use the appropriate responsible body and procedure for the person’s age and circumstances. A private report is not a DoLS authorisation and Liberty Protection Safeguards should not be described as an operational replacement merely because legislation exists.
14Key takeaway
Keep supported MCA decision-making and Article 5 analysis distinct. Look at the actual arrangements and the person’s wishes, investigate consent carefully and use the appropriate safeguards where liberty may be deprived. Seek review where the position is uncertain.
15Frequently asked questions
What type of assessment is right for deprivation of liberty cases?
Identify whether the question concerns capacity, best interests, deprivation of liberty or more than one of these. Formal DoLS assessments and court evidence have their own requirements; an independent commercial report is not automatically the correct or sufficient route.
Does a diagnosis automatically mean someone lacks capacity?
No. A diagnosis does not establish lack of capacity. For a decision under the Mental Capacity Act, consider the relevant information and practicable support, then assess understanding, retention, use or weighing and communication by any means. Any inability must be caused by an impairment of, or disturbance in the functioning of, the mind or brain. Will-making has its own legal test.
Does the Cheshire West acid test still decide deprivation of liberty?
No. AGNI replaced reliance on the Cheshire West acid test with a multifactorial approach. Supervision and freedom to leave remain relevant but are not alone determinative. Consult the judgment and current government guidance, updated 22 September 2026, and do not assume lack of objection means valid consent.

17Practical next steps
If restrictions or consent are uncertain, raise the concern with the responsible care provider and local authority or the solicitor handling the court route. Do not end an authorisation or assume safeguards are unnecessary solely because the person appears settled.
