Persons Unknown

General Principles

37.

The decision of the Supreme Court in Wolverhampton City Council and others v London Gypsies and Travellers and others[2023] UKSC 47 makes plain that any claim and application for injunctive relief against newcomer Persons Unknown is to be treated differently to those against named defendants. In particular a Claimant must show a ‘compelling need’ for the order sought (at Paragraph 218):

“any [claimant] applying for an injunction against persons unknown, including newcomers … must satisfy the court by full and detailed evidence that there is a compelling justification for the order sought … There must be a strong probability that a tort … is to be committed and that this will cause real harm. Further the threat must be real and imminent.”

38.

Following Wolverhampton, Ritchie J summarised the requirements for an injunction against persons unknown in Valero Energy Ltd v Persons Unknown [2024] EWHC 134 (KB). In particular a number of substantive and procedural requirements must be satisfied before relief could be granted.

39.

The substantive requirements are:

i)

there must be a cause of action;

ii)

there must be full and frank disclosure by the claimant;

iii)

there must be sufficient evidence to prove the claim (although this requirement appears to be crafted with the summary judgment application in mind);

iv)

there must be no realistic defence;

v)

there must be a compelling justification for the remedy sought, and the court must take into account any balancing exercised that may be required if article 10 and 11 rights are engaged;

vi)

damages must not be an adequate remedy.

40.

The procedural requirements are:

i)

Persons Unknown must be clearly and plainly identified by reference to the tortious conduct to be prohibited, and clearly defined geographical boundaries (if possible);

ii)

the prohibitions in the injunction must be set out in clear words and avoid legal terminology. Further, if any lawful conduct is sought to be prohibited, that must be made clear, and the Court must be satisfied that there is no other more proportionate way of protecting the claimant’s rights;

iii)

the prohibitions must match the torts claimed;

iv)

the prohibitions must be defined by clear geographic boundaries (if possible);

v)

the injunction should be temporally limited to that which is reasonably necessary to protect the claimant’s rights;

vi)

the proceedings and any order made must be served by alternative means (referred to as ‘notification’ and not service in Wolverhampton). The court should have regard to the Human Rights Act 1998, s12(2);

vii)

there must be a right to set aside or vary any order made;

viii)

provision should be made for the review of the injunction in the future.

41.

On the basis that in this case the Claimant is seeking an element of precautionary relief the Court would usually be required to have regard to the multi-factorial test stated by Marcus Smith J in Vastint Leeds BV v Persons Unknown[2019] 4 WLR 2. That test requires these two questions to be answered in the affirmative before injunctive relief could be granted:

i)

First, is there a strong possibility that, unless restrained by an injunction, the defendant will act in breach of the claimant’s rights?; and

ii)

Second, if the defendant did act in contravention of the claimant’s rights, would the resulting harm be so grave and irreparable that, notwithstanding the grant of an immediate interlocutory injunction (at the time of the actual infringement of the claimant’s rights) to restrain further occurrence of the acts complained of, a remedy of damages would be inadequate.

42.

Those questions are to be addressed by reference to the following factors:

i)

in relation to the first question: if the infringement is purely anticipatory, what steps has the claimant taken to ensure that the infringement does not occur; the attitude of the defendants; where infringements have already been committed, it may be that the defendant’s intentions are less significant than the natural and probable consequences of his or her act; the time frame between the application for relief and the threatened infringement may be relevant (the courts often use the language of imminence, meaning that the remedy sought must not be premature);

ii)

in relation to question two: how easily can the harm of the infringement be undone by ex post rather than ex ante intervention; the gravity of the anticipated harm.

43.

In Rochdale MBC v Persons Unknown [2025] EWHC 1314 (KB) Garnham J considered the Vastint test and how it sat alongside the Wolverhampton framework and concluded at Paragraph 78:

“In my judgment, the test articulated by Marcus Smith J in Vastint Leeds BV v Persons Unknown [2019] 4 WLR 2 and approved by Sir Geoffrey Vos MR in Barking and Dagenham v Persons Unknown [2022] EWCA Civ 13 has been subsumed into the Wolverhampton framework. The Vastint test, however, provides a useful double check.”

Approach to ‘review’

44.

At Paragraph 225 of the Judgement in Wolverhampton the Supreme Court observed that the temporal limitation and periodic review of newcomer injunctions provides:

“all parties an opportunity to make full and complete disclosure to the court, supported by appropriate evidence, as to how effective the order has been; whether any reasons or grounds for its discharge have emerged; whether there is any proper justification for its continuance; and whether and on what basis a further order ought to be made.”

45.

A series of recent decisions have considered how the Court should approach the review exercise. In High Speed Two (HS2) Ltd v Persons Unknown [2024] EWHC 1277 (KB) (‘HS2’),Ritchie J considered the correct approach and concluded that (at Paragraph 32):

“Drawing these authorities together, on a review of an interim injunction against PUs and named Defendants, this Court is not starting de novo. The Judges who have previously made the interim injunctions have made findings justifying the interim injunctions. It is not the task of the Court on review to query or undermine those. However, it is vital to understand why they were made, to read and assimilate the findings, to understand the sub-strata of the quia timet, the reasons for the fear of unlawful direct action. Then it is necessary to determine, on the evidence, whether anything material has changed. If nothing material has changed, if the risk still exists as before and the claimant remains rightly and justifiably fearful of unlawful attacks, the extension may be granted so long as procedural and legal rigour has been observed and fulfilled.

On the other hand, if material matters have changed, the Court is required to analyse the changes, based on the evidence before it, and in the full light of the past decisions, to determine anew, whether the scope, details and need for the full interim injunction should be altered. To do so, the original thresholds for granting the interim injunction still apply.”

46.

The same approach was taken by Morris J in Transport for London v Persons Unknown & Ors [2025] EWHC 55 (KB) and by Hill J when conducting the annual review in Valero Energy Ltd v Persons Unknown [2025] EWHC 207 (KB).

47.

In Basingstoke & Deane BC v Persons Unknown [2025] EWHC 738 the Court took a different approach and conducted a further full Wolverhampton assessment. However, in Rochdale Garnham J considered that Basingstoke could be regarded as an outlier for good reason on the facts and held that:

“In my judgment the correct approach is dictated by the Supreme Court’s judgment in Wolverhampton and in particular [225]. This is not a “tick box” exercise, but the matters on which evidence should be adduced and argument focussed are (i) how effective the order has been; (ii) whether any reasons or grounds for its discharge have emerged; (iii) whether there is any proper justification for its continuance; and (iv) whether and on what basis a further order ought to be made. The parties should give full disclosure, supported by appropriate evidence, directed towards those questions.”

48.

In this case Miss Pratt submits that there has been no change of circumstance that would necessitate a full Wolverhampton assessment and that I should follow the approach taken in Rochdale and other cases, effectively treating Basingstoke as an outlier.

49.

I accept the Claimant’s submission as to the correct approach to review in this case. This is not a de novo hearing of the application for a Persons Unknown Order, and the Court has previously, and on two occasions, performed a full Wolverhampton assessment alongside a Ziegler proportionality assessment. The process of annual review provides an additional check and balance on an Order that has already been the subject of anxious scrutiny against stringent criteria. The purpose of the review is to ensure that there has been no change of circumstance as would mean that the continuation of the order was unnecessary or that it should otherwise be discharged or varied.

Form of any Order

50.

Miss Pratt referred the Court, in discharging the Claimant’s obligation for full and frank disclosure, to the decision of Nicklin J in MBR Acres Limited & Ors v Curtin & Persons Unknown [2025] EWHC 331 (KB) (a decision handed down after the Order made by Tipples J in this case).

51.

That decision, is notable for two reasons:

i)

Nicklin J granted a true contra mundum order on the basis of the decision of the Supreme Court in Wolverhampton and found that Persons Unknown did not need to be, and ought not to be, defined in any way; and;

ii)

Nicklin J included within the contra mundum order a requirement that the court’s permission must be obtained before a contempt application could be made.

52.

Having drawn my attention to that decision Miss Pratt nonetheless urged me not to vary the form of any order I am willing to make in this case so as to make it a truly contra mundum order. She submitted that such an approach would be inconsistent with the approach taken in a number of other cases decided post Wolverhampton, and that although Fordham J followed the same approach as Nicklin J at the first hearing of a without notice application in The Chancellor, Master and Scholars of the University of Cambridgev Persons Unknown [2025] EWHC 454 (KB), that approach was not followed by the Soole J on the return date who preferred and adopted the ‘conventional’ approach (See [2025] EWHC 724 (KB)).

53.

Miss Pratt further submits that I should not impose a permission condition in this case. Accepting that such conditions have featured in some other recent injunctions (See for example Trinity College Cambridge v Persons Unknown and St John’s College Cambridge v Persons Unknown [2025] EWHC 1577 (Ch)), she submits that:

(i)

The Claimant making a contempt application does so at their own risk including as to costs;

(ii)

There is no reason to suspect that the Claimant in this case would seek to bring vexatious or ill-founded contempt applications before the Court; and

(iii)

The introduction of a permission requirement is therefore an unnecessary step at this stage.
