Is it possible to gain an injunction to prevent industrial action?

It is possible for an employer to gain an injunction to prevent industrial action if that action would be unlawful, for example if the union has not complied with the statutory requirements on balloting and notification.

The Employment Relations Act 1999 removed the obligation on unions to identify members being balloted by name and required "accidental" failures to comply with the requirements to be disregarded. The scope for obtaining injunctive relief is therefore severely restricted.
