Deprivation of Liberty Safeguards: Practical Examples and Medico-Legal Considerations

Deprivation of Liberty Safeguards: Practical Examples and Medico-Legal Considerations
Understanding Deprivation of Liberty Safeguards (DoLS) is essential for legal professionals handling clinical negligence, personal injury, and human rights cases. The Mental Capacity Act 2005 (MCA 2005) provides the statutory framework for DoLS, protecting individuals aged 18 and over who lack capacity to consent to care arrangements that deprive them of liberty.
For solicitors, cases involving alleged unlawful deprivation of liberty or DoLS process failures require a nuanced grasp of clinical practice and legal requirements. Expert witness evidence often determines whether a deprivation was lawful, proportionate, and in the individual’s best interests.
Key Legal Principles
The Supreme Court’s P v Cheshire West and Chester Council [2014] ruling established the ‘acid test’ for deprivation of liberty. An individual is deprived of liberty if they are:
- Not free to leave, and
- Subject to continuous supervision and control.
These conditions apply regardless of the person’s compliance or contentment. The individual’s mental capacity status is central to DoLS applicability.
Practical Examples of Deprivation of Liberty
Hospital Settings
A patient with severe delirium or neurodegenerative condition may be prevented from leaving a ward, require constant observation, and have movements restricted (e.g., bed rails, secured bays) to ensure safety and facilitate treatment. These restrictions constitute deprivation of liberty when the individual lacks capacity to consent.
Care Home Environments
A resident with advanced dementia unable to leave independently, with locked doors and scheduled daily activities monitored by staff, meets the deprivation of liberty criteria. The restrictions must be necessary to prevent harm and in the person’s best interests.
Supported Living Arrangements
While DoLS formally applies only to hospitals and care homes, similar principles apply to supported living. For example, a person with severe learning disabilities in a residential setting with highly restricted movements and one-to-one supervision for all community access would typically require Court of Protection authorisation.
Capacity Assessment Framework
The MCA 2005 outlines a two-stage capacity test:
- Is there an impairment of, or disturbance in, the functioning of the mind or brain?
- Does that impairment mean the person cannot make a specific decision when needed?
Clinical experts assess capacity using diagnostic criteria from DSM-5 or ICD-11, reviewing medical records and often conducting direct assessments. Conditions frequently associated with impaired capacity include:
- Dementia and neurodegenerative conditions
- Severe learning disabilities
- Traumatic brain injuries
- Severe mental illnesses
Medico-Legal Implications
DoLS failures or unlawful deprivations have significant legal consequences:
Clinical Negligence Claims
Solicitors may allege breach of duty where providers failed to recognise deprivation of liberty, apply for DoLS authorisation, or implement least restrictive care plans. Expert evidence addresses whether professional standards were met (applying Bolam and Bolitho tests).
Human Rights Considerations
Alleged unlawful deprivations engage Article 5 ECHR (right to liberty). Expert reports evaluate whether state actions were proportionate and lawful.
Inquest Proceedings
Where a person subject to DoLS dies, expert evidence assists coroners in understanding care circumstances, particularly if DoLS authorisation is contested (under Coroners Regulations 2013).
Expert Witness Role
CPR Part 35-compliant expert witnesses provide independent opinions on:
- Capacity assessments (retrospective or current)
- Best interests determinations
- Standard of care evaluations
- Causation and prognosis
Subspecialty matching is crucial. Cases involving:
- Dementia require geriatricians or old age psychiatrists
- Learning disabilities need specialist psychiatrists
- Traumatic brain injuries require neuropsychiatrists or neurologists
Practical Guidance for Legal Practitioners
Early expert instruction is beneficial when:
- Capacity questions arise
- Care arrangements’ lawfulness is disputed
- Restrictions’ appropriateness is challenged
Provide experts with comprehensive records including:
- Medical records
- Care plans
- Capacity assessments
- DoLS authorisations
- Safeguarding reports
Specify questions referencing legal tests (MCA 2005 capacity, Cheshire West ‘acid test’, Bolam/Bolitho). For complex cases involving multiple clinical issues, consider multi-disciplinary input from relevant specialties.
Future Considerations: Liberty Protection Safeguards
The forthcoming Liberty Protection Safeguards (LPS) will replace DoLS, extending protections to 16-17 year olds and covering domestic settings. LPS will introduce new authorisation processes and responsibilities for care providers, requiring legal practitioners to stay updated on these developments.
