Discretionary powers
26. Where immediately before a transferred employee was first transferred under the Act it was the prevailing practice of the authority employing him, in relation to employees of that description, to exercise beneficially (that is to say, to secure the making of payments or increased payments) any discretionary power referred to in article 21 or under any provision mentioned in article 23, it shall be the duty of any authority to which he is transferred under the Act, and in whose employment he has continued without a break of twelve months or more, to exercise in relation to him that power (or any corresponding power under statutory provisions relating to pensions for the time being in force) in a way which is no less beneficial than that practice; and section 35 of the Act of 1937 shall apply to any question arising under this article.
