In deciding whether to grant, renew or revoke an exemption, the Tribunal must consider—
(a) whether the proposed exemption is unnecessary because—
(i) an exception or exemption in this Act already applies to the conduct sought to be exempted; or
(ii) the conduct sought to be exempted would not amount to prohibited discrimination; and
(b) whether the proposed exemption is a reasonable limitation on the right to equality set out in the Charter of Human Rights and Responsibilities; and
(c) all the relevant circumstances of the case.
