Mental Capacity Act 2005


The Mental Capacity Act 2005 is an Act of the Parliament of the United Kingdom applying to England and Wales. Its primary purpose is to provide a legal framework for acting and making decisions on behalf of adults who lack the capacity to make particular decisions for themselves.

Key features of the Act

The five statutory principles

The five principles are outlined in the Section 1 of the Act. These are designed to protect people who lack capacity to make particular decisions, but also to maximise their ability to make decisions, or to participate in decision-making, as far as they are able to do so.

Summary of other key elements of the Act

The following orders have been made under this section:
The new measures that the Act introduced were:
April 2007
October 2007
In response to the ruling by the European Court of Human Rights in HL v UK the Act was amended by the Mental Health Act 2007 in July that year. These additions are known as the Deprivation of Liberty Safeguards, and were implemented in April 2009. These amendments created administrative procedures to ensure the Act's processes are observed in cases of adults who are, or may be, deprived of their liberty in care homes or hospitals, thus protecting health and social care providers from prosecution under human rights legislation.
Key elements of the DoLS are that the person must be provided with a representative and given the right to challenge the deprivation of liberty through the Court of Protection, and that there must be a mechanism for the deprivation of liberty to be reviewed and monitored regularly.
The DoLS were introduced in response to the Bournewood case, on which the European Court of Human Rights ruled in October 2004 that a detention of an incapacitated patient which did not comply with Article 5 of the European Convention on Human Rights had taken place; in particular, a person who is detained must be told the reasons for the detention and must also, under Article 5, have the right of speedy access to a court to appeal against the detention.

Mental Capacity (Amendment) Bill 2019

The . This act will replace DoLS with a new legal framework called Liberty Protection Safeguards. These will be used for anyone 16 or above who lacks capacity rather than 18 as previously used in DoLS. The "acid test' from the Cheshire West case remains, there is still not statuary definition of deprivation of liberty. Target date for implementation is October 2020.
