The Mental Capacity Act (MCA) 2005 protects and empowers vulnerable adults who are not able to make decisions for themselves. This might be because of:
- a learning disability
- dementia
- a mental health problem
- a head injury/stroke
- a drug, alcohol or substance addiction
The Act sets out a legal framework of how to act on behalf of someone who lacks the capacity to make a specific decision. These may be decisions about day-to-day matters like what to buy when doing the weekly shop. They may be decisions about major life changing events, like whether the person should move into a care home or have a major surgical operation.
It also allows people to plan for a time when they may lack mental capacity in the future.
The Act sets out in five statutory principles to ensure the right action is taken in individual cases:
- 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 have been taken without success.
- A person is not to be treated as unable to a make a decision just because they make an unwise decision.
- An act or decision done under this Act for a person who lacks capacity must be made in their best interests.
- Before the act or decision is carried out, it must be considered whether the intended purpose can be achieved effectively in a way that is less restrictive of the person’s rights and freedom of action.
