Q

5 key principles of mental capacity.

A

1) A person is assumed to have capacity until it is established that the person lacks it.

2) A person should not be treated as unable to decide, unless all practicable steps to help them have failed.

3) A person should not be treated as unable to decide just because it is unwise.

4) Decisions made on behalf of an incapable person must be in their best interests.

5) Regard should be taken to find the solution which is least restrictive of the person’s rights and freedom of action.
