Jockey Club Racecourses Ltd v Persons Unknown

Applying Wolverhampton CC v London Gypsies and Travellers, a landowner may obtain a final 'newcomer' injunction against persons unknown to restrain anticipated trespass and disruption where there is a compelling justification, provided the order has clear terms, defined geographic and temporal limits, effective notice and service, a periodic-review mechanism and liberty to apply, and the claimant's proprietary rights are properly balanced against the Article 10 and 11 rights of protesters.
