In determining what is reasonable on a reference or application under this Part relating to a licensing scheme or licence, the High Court shall have regard to—
(a) the availability of other schemes, or the granting of other licences, to other persons in similar circumstances; and
(b) the terms of those schemes or licences,
and shall exercise its powers so as to secure that there is no unreasonable discrimination between licences, or prospective licensees, under the scheme or licence to which the reference or application relates and licensees under other schemes operated by, or other licences granted by, the same person.
