A Guide To The Mental Capacity Act 2005

The MCA 2005 together with its regulations came into force on 1 October 2007.

The Act is principally designed to improve and clarify how decisions should be made for those persons over 16 who are otherwise unable to make decisions for themselves.

Who should make the decision?

How and when should they make the decision?
The decision-maker must be guided by the 5 governing principles (s.1 MCA)

The 5 Governing Principles

1.The Presumption of Capacity

A person must be assumed to have capacity unless it is established that he lacks capacity

Establishing a lack of capacity

A person lacks capacity if “at the material time he is unable to make a decision for himself in relation to the matter because of an impairment of or disturbance in the functioning of the mind or brain.”

This involves a two-stage test:

Does the person have an impairment of or a disturbance in the functioning of the mind or brain?

  • E.g. dementia/long-term brain damage
  • Medical question

Does that impairment/disturbance render the person unable to make a specific decision?

  • A person will be unable to make a specific decision if, on the balance of probabilities, they cannot:
    • Understand information about the decision to be made;
    • Retain that information;
    • Use or weigh that information as part of the process of making the decision; or
    • Communicate his decision (s.3 MCA)

Difficulties with communication do not amount to an inability to communicate.

A person can lack capacity even if the loss of capacity is partial or temporary or if capacity fluctuates.

2. A person is not to be treated as unable to make a decision unless all practicable steps to help him do so have been taken without success

This will involve:

  • Providing relevant information
  • Communicating it in an appropriate way
  • Making the person feel at ease
  • Supporting the person

What level of help should be given will depend upon the individual circumstances and, in particular, the decision to be made and the length of time to make it.

3. A person is not to be treated as unable to make a decision merely because he makes an unwise decision

4. Best Interests

An act done or decision made for or on behalf of a person who lacks capacity must be done, or made, in his best interests

What should be considered?

Decisions as to best interests must NOT be based solely on:

  • Age
  • Appearance
  • Condition
  • Behaviour

All the relevant circumstances: i.e. circumstances which:

  • The person making the decision is aware of; and
  • It would be reasonable to regard as relevant (s.4(11) MCA)

Every effort should be made to encourage and enable the person lacking capacity to take part in the decision-making process

If there is a chance that the person will regain capacity to make a particular decision it may be possible to put off the decision until later

Special considerations apply to life sustaining treatment

  • Questions as to what is ‘life sustaining treatment’ are medical decisions properly left to doctors
  • Any decisions relating to life sustaining treatment must not be motivated by desire to bring about a person’s death – even if out of compassion
  • All reasonable steps which are in the person’s best interests should be taken to prolong their life
  • Doctors are not under an obligation to provide/continue to provide life sustaining treatment where such treatment is not in the person’s best interests
  • Advance decisions must be followed provided they are:
    • In writing;
    • Signed and witnessed; and
    • State clearly that the decision applies even if life is at risk.

A person’s past and present wishes and feelings, beliefs and values should be taken into account

  • Applies if such wishes etc. are ‘reasonably ascertainable’ – this will depend on the circumstances and time available
  • This allows actions to benefit other people provided that they are in the best interests of the person who lacks capacity (This is an adaptation of common law approach in Re Y. In that case a bone marrow transplant for the benefit of Y’s sister was deemed to be in Y’s best interests because she would have suffered as a result of the effect her sister’s death on her mother. The new approach would entitle a decision-maker in those circumstances to consider that, in light of her relationship with her family, a person in Y’s position would have wanted to undergo the procedure).

Views of other people who are close to the person who lacks capacity should be considered as well as the views of an attorney or deputy

The decision-maker has a duty to take into account the views of:

  • Anyone the person previously named as someone they wanted consulted
  • Anyone involved in caring for the person
  • Anyone interested in their welfare (e.g. family carers or close relatives)
  • An Attorney appointed under an LPA
  • A Deputy appointed by the Court of Protection

The decision-maker should try to establish what they these people believe is in the person’s best interests and ascertain whether they have any information on their wishes and feelings, beliefs and values.

NB: Attorneys and deputies must make the decisions in areas they have been appointed to deal with.

Protection from liability

If someone acts or makes a decision in the reasonable belief that what they are doing is in the best interests of the person who lacks capacity, then, provided they have followed the s.4 checklist, they will have complied with their duty (s.4(9))

5.Minimising intervention

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 effectively achieved in a way that is less restrictive of the person’s rights and freedom of action.

The decision-maker should consider whether there is a need to act or make a decision at all.
