(2)It does not matter whether the impairment or disturbance is permanent or temporary.
(3)A lack of capacity cannot be established merely by reference to—
(a)a person's age or appearance, or
(b)a condition of his, or an aspect of his behaviour, which might lead others to make unjustified assumptions about his capacity.
(4)In proceedings under this Act or any other enactment, any question whether a person lacks capacity within the meaning of this Act must be decided on the balance of probabilities.
(5)No power which a person (“D”) may exercise under this Act—
(a)in relation to a person who lacks capacity, or
(b)where D reasonably thinks that a person lacks capacity,
is exercisable in relation to a person under 16.

(b)are exercisable by a person under this Act where he reasonably believes that another person lacks capacity.
(9)In the case of an act done, or a decision made, by a person other than the court, there is sufficient compliance with this section if (having complied with the requirements of subsections (1) to (7)) he reasonably believes that what he does or decides is in the best interests of the person concerned.
(10)“Life-sustaining treatment” means treatment which in the view of a person providing health care for the person concerned is necessary to sustain life.
(11)“Relevant circumstances” are those—
(a)of which the person making the determination is aware, and
(b)which it would be reasonable to regard as relevant.

Yn ddilys o 01/10/2007
(1)If a person (“D”) does an act in connection with the care or treatment of another person (“P”), the act is one to which this section applies if—
(a)before doing the act, D takes reasonable steps to establish whether P lacks capacity in relation to the matter in question, and
