Overview of the Mental Capacity Act 2005
Everyone working with and/or caring for an adult who may lack capacity to make specific decisions must comply with the Act when making decisions or acting for that person, when the person lacks the capacity to make a particular decision for themselves.
The same rules apply whether the decisions are life-changing events or everyday matters.
The underlying philosophy of the Act is to ensure that any decision made, or action taken, on behalf of someone who lacks the capacity to make the decision or act for themselves is made in their best interests.
The Act introduces several new roles, bodies and powers, all of which will support the Act’s provisions. These include:
- Attorneys appointed under Lasting Powers of Attorney
- The new Court of Protection, and court-appointed deputies
- Independent Mental Capacity Advocates (IMCAs)
Five statutory principles
Section 1 of the Act sets out the five statutory principles, the values that underpin the legal requirements in the Act.
The five statutory principles are:
- A person must be assumed to have capacity unless it is established that they lack capacity.
- A person is not to be treated as unable to make a decision unless all practicable steps to help him to do so have been taken without success.
- A person is not to be treated as unable to make a decision merely because he makes an unwise decision.
- An act done, or decision made, under this Act for or on behalf of a person who lacks capacity must be done, or made, in his best interests.
- Before the act is done, or the decision is made, regard must be had to whether the purpose for which it is needed can be as effectively achieved in a way that is less restrictive of the person’s rights and freedom of action.
