Section 16. Immunity from civil suit in certain cases

(1) No suit or other legal proceeding shall be maintainable in any civil court against any registered Trade Union or any office-bearer or member thereof in respect of any act done in contemplation or furtherance of an industrial dispute to which a member of the 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.

(2) A registered Trade Union shall not be liable in any suit or other legal proceeding in any civil court in respect of any tortuous act done in contemplation or furtherance of an industrial dispute by an agent of the Trade Union if it is proved that such person acted without the knowledge of, or contrary to express instructions given by, the executive of the Trade Union.
