The Mental Capacity Act 2005 (MCA) is designed to protect and empower individuals who are aged 16 or older who may lack the capacity to make their own decisions about their care and treatment.  It also gives those who care for them a clear framework within which to work.

The MCA Code of Practice supporting the legislation must be followed by anyone making decisions on behalf of another adult, whether in a paid or unpaid role.  The underlying philosophy of the MCA 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.

Section 1 of the Act sets out the five ‘statutory principles’ – the values that underpin the legal requirements in the Act. The Act is intended to be enabling and supportive of people who lack capacity, not restricting or controlling of their lives. It aims 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. 

1) A person is presumed to have capacity unless proven otherwise

2) The person cannot be treated as lacking capacity until all practicable steps have been taken to help them make the decision without success

3) An unwise decision is not to be taken as a lack of capacity

4) All actions taken on behalf of a person lacking capacity must be taken in their best interests

5) Before doing something, consider whether the aim could be achieved by using a less restrictive intervention

One of the key principles of the Act is that any act done for, or any decision made on behalf of a person who lacks capacity must be done, or made, in that person’s best interests. That is the same whether the person making the decision or acting is a family carer, a paid care worker, an attorney, a court-appointed deputy, or a healthcare professional, and whether the decision is a minor issue – like what to wear – or a major issue, like whether to provide particular healthcare. As long as these acts or decisions are in the best interests of the person who lacks capacity to make the decision for themselves, or to consent to acts concerned with their care or treatment, then the decision-maker or carer will be protected from liability.  There are some exceptions which are defined in the Code of Practice.

Principles;

• The person’s wishes, feelings, beliefs and values must be taken into consideration
• The person must be involved in the decision as much as they are able to be
• The views of others involved in their care must be considered
• Consideration must be given as to whether the person might regain capacity     and whether the decision could be postponed until then
• All the relevant circumstances must be considered
• Judgements must be made in an equal and non-discriminatory way
• When decisions involve life sustaining treatments, decisions cannot be made with the purpose of bringing about a person’s death
