3.—(1) This section applies in connection with the requirement in section 2(1)(b) that a purpose falling within section 2(2) must be for the public benefit if it is to be a charitable purpose.
(2) In determining whether that requirement is satisfied in relation to any such purpose, it is not to be presumed that a purpose of a particular description is for the public benefit.
(3) In determining whether an institution provides or intends to provide public benefit, regard must be had to—
(a)how any—
(i)benefit gained or likely to be gained by members of the institution or any other persons (other than as members of the public), and
(ii)detriment incurred or likely to be incurred by the public,
in consequence of the institution exercising its functions compares with the benefit gained or likely to be gained by the public in that consequence, and
(b)where benefit is, or is likely to be, provided to a section of the public only, whether any condition on obtaining that benefit (including any charge or fee) is unduly restrictive.
