Section 5
Inability to make decisions
(1)
For the purposes of section 4, a person is unable to make a decision for himself or herself if the person is unable —
to understand the information relevant to the decision;
to retain that information;
to use or weigh that information as part of the process of making the decision; or
to communicate his or her decision (whether by talking, using sign language or any other means).
(2)
A person is not to be regarded as unable to understand the information relevant to a decision if the person is able to understand an explanation of it given to him or her in a way that is appropriate to his or her circumstances (using simple language, visual aids or any other means).
(3)
The fact that a person is able to retain the information relevant to a decision for a short period only does not prevent the person from being regarded as able to make the decision.
(4)
The information relevant to a decision includes information about the reasonably foreseeable consequences of —
deciding one way or another; or
failing to make the decision.
