Mental Capacity Act

The Mental Capacity Act 2005 provides a legal framework to protect and support people who are unable to make decisions for themselves. It also offers guidance for professionals and others who need to make decisions on behalf of someone who lacks the mental capacity to do so. The Act applies to decisions about health and social care, property and financial affairs, as well as everyday decisions such as personal care, clothing and nutrition. It also enables people to plan ahead for a time when they may no longer be able to make decisions independently.

Understanding Mental Capacity

Mental capacity is both decision-specific and time-specific. A person may have capacity to make some decisions but not others, and their ability to make decisions may change over time. Mental capacity concerns situations where an individual is unable to make a decision because of an impairment or disturbance in the functioning of their mind or brain. This may be caused by:

  • Dementia
  • Learning disabilities
  • Mental health conditions
  • Brain injury
  • The effects of drugs or alcohol
  • Illness or medical treatment affecting cognition

A person is considered to lack capacity if they cannot:

  • Understand the information relevant to a decision.
  • Retain that information long enough to make the decision.
  • Weigh up the information as part of the decision-making process.
  • Communicate their decision by any means.
Making Decisions in a Person's Best Interests

Where a person lacks capacity to make a specific decision, any decision made on their behalf must be in their best interests. This includes taking into account the person’s:

  • Wishes and feelings
  • Beliefs and values
  • Past and present views and preferences

The Mental Capacity Act places the individual at the centre of the decision-making process and promotes their rights, independence and involvement wherever possible.

Advocacy

If following a mental capacity assessment, the decision maker finds the person who lacks mental capacity does not have anyone whom can be consulted they are deemed to be ‘unbefriended’. This means they have no family or friends that can be consulted so a person called an Independent Mental Capacity Advocate (IMCA) can be appointed as part of the best interest decision making process. Information on Wolverhampton’s current Advocacy Service can be found here along with how and when to make a referral.

Key Principles of the Mental Capacity Act

The Act is underpinned by five statutory principles:

  1. Every adult must be assumed to have capacity unless it is established otherwise.
  2. A person must be supported to make their own decisions before it is concluded that they lack capacity.
  3. Individuals have the right to make unwise decisions.
  4. Any action or decision made on behalf of someone who lacks capacity must be in their best interests.
  5. Any intervention should be the least restrictive option available.
Human Rights and the Mental Capacity Act

Professionals must always promote and uphold the human rights of the people they support. Any restrictive intervention must be lawful, proportionate and compliant with the Human Rights Act 1998. Respecting a person’s dignity, rights and freedoms should remain central to all decision-making.
