TRADE UNIONS ORDINANCE - SECT 42

Immunity from civil suit in certain cases

No suit or other legal proceeding shall be maintained in any civil court
against a registered trade union in respect of any act done in contemplation
or furtherance of a trade dispute to which a member of such trade union is a
party on the ground only that such act induces some other person to break a
contract of employment or that it is an interference with the trade, business
or employment of some other person or with the right of some other person to
dispose of his capital or of his labour as he wills.
