The appropriate authority may make regulations as to the functions of independent mental capacity advocates.
The regulations may, in particular, make provision requiring an advocate to take such steps as may be prescribed for the purpose of—
providing support to the person whom he has been instructed to represent ("P") so that P may participate as fully as possible in any relevant decision;
obtaining and evaluating relevant information;
ascertaining what P's wishes and feelings would be likely to be, and the beliefs and values that would be likely to influence P, if he had capacity;
ascertaining what alternative courses of action are available in relation to P;
obtaining a further medical opinion where treatment is proposed and the advocate thinks that one should be obtained.
The regulations may also make provision as to circumstances in which the advocate may challenge, or provide assistance for the purpose of challenging, any relevant decision.
