(3)Where in pursuance of any agreement the acts in question in relation to any offence are to be done in contemplation or furtherance of a trade dispute (within the meaning of the Trade Union and Labour Relations Act 1974) that offence shall be disregarded for the purposes of subsection (1) above provided that it is a summary offence which is not punishable with imprisonment.
