3.—(1) A nomination shall be revoked—
(a)by the death of the nominee, or, where there is more than one nominee, by the death of all the nominees, in the lifetime of the nominator;
(b)so far as relates to the interest thereunder of any nominee (being one of two or more nominees), by the death of that nominee in the lifetime of the nominator, unless the interest of that nominee is disposed of by the nomination;
(c)by the subsequent marriage of the nominator;
(d)by written notice of revocation signed by the nominator and delivered at or sent to the principal office of the trade union during the lifetime of the nominator;
(e)by a subsequent nomination duly made in accordance with these Regulations by the same nominator disposing of either the whole or any part of the moneys disposed of by the earlier nomination, but so far only as respects those moneys or that part of those moneys, as the case may be;
but a nomination shall not be revoked by any will or by any other act, or means whatsoever.
(2) Notwithstanding that a nomination has been revoked by the marriage of the nominator, where the trade union has paid the money to the nominee in ignorance of that marriage, the payment shall be valid as if the nomination had not been so revoked.
