Ineos Upstream Ltd and Others v Persons Unknown and Others: ChD 23 Nov 2017

The claimant sought an injunction expressed to be against unknown persons.
Held: Morgan J expressed a degree of concern about orders having this effect, but concluded that (particularly in light of the South Cambridgeshire decision) this procedure was now open to claimants in cases outside section 187B of the Town and Country Planning Act 1990: ‘ I was concerned at the idea that the court might be asked to grant a quia timet injunction against persons who had not yet committed the acts which the injunction would prevent them from doing but yet they would be defined as defendants as Persons Unknown who have committed such acts. For example, the First Defendants are defined as Persons Unknown entering or remaining on specified areas of land but when the proceedings were issued and the ex parte injunctions were granted, no one had entered on the specified land as a trespasser (subject to the possibility that there might have been a trespass on Site 1). Proceeding in this way would seem to produce the result that at the time when the court made its order there were no persons within the defined category of Persons Unknown. How then, later, did some persons come within that category and become subject to the court’s order? Did they become parties by their unilateral action which was action forbidden by the court’s order?’
