“The guiding principles must, I think, be – (1) that the jurisdiction is to be invoked and exercised exceptionally and with great caution: see the authority already cited; (2) that there must certainly be something more than mere infringement of the criminal law before the assistance of civil proceedings can be invoked and accorded for the protection or promotion of the interests of the inhabitants of the area: see the Stoke-on-Trent case at 767B, 776C, and Wychavon District Council v. Midland Enterprises (Special Events) Ltd. [1987] 86 L.G.R. 83 at 87; (3) that the essential foundation for the exercise of the court's discretion to grant an injunction is not that the offender is deliberately and flagrantly flouting the law but the need to draw the inference that the defendant's unlawful operations will continue unless and until effectively restrained by the law and that nothing short of an injunction will be effective to restrain them: see the Wychavon case at page 89.”
"The application of those principles means that if the court is satisfied that nothing short of an injunction will be effective to restrain a defendant's unlawful operations it may grant an injunction even though he has not yet been subjected to the maximum penalty available under the criminal law."
