17Restriction on grant of ex parte injunctions and interdicts
Where an application for an injunction or interdict is made to a court in the absence of the party against whom the injunction or interdict is sought or any representative of his, and that party claims, or in the opinion of the court would be likely to claim, that he acted in contemplation or furtherance of a trade dispute, the court shall not grant the injunction or interdict unless satisfied that all steps which in the circumstances were reasonable have been taken with a view to securing that notice of the application and an opportunity of being heard with respect to the application have been given to that party.
