If an official user makes a groundless threat to make an application or bring an action under this Act, any person aggrieved may bring an action in a relevant court seeking a declaration or injunction, or damages for loss that the person has suffered as a result of the threat.

A person may not bring or continue such an action if the official user has made an application, or brought an action, under Part   5 against the threatened person in relation to the act, or proposed act, to which the threat related.

It is a defence for an official user that the conduct of the threatened person, in relation to which the threat was made, contravenes section   16.

An official user may make a counterclaim for any relief to which the official user would be entitled under Part   5.
