How a county council has obtained an injunction against those hoisting flags on the public highway

24th June 2026

A guided tour of the High Court injunction against “persons unknown”

UPDATE – since the post below, the Council has now published other legal documents regarding the injunction here.

*

Yesterday it was reported that Oxfordshire County Council had obtained a High Court injunction against those placing St George’s flags on the public highway.

This followed the earlier news of the council’s application.

The council itself published a helpful and detailed post on the injunction on its own site, which is worth reading in full (excerpt below).

*

This blog has now obtained a copy of the Order of the High Court, and it sets out below what the Order says and what can be inferred about the case from the Order.

Although the Order is a public document, and so can by obtained by anyone reading this post, this blog does not propose to publish the Order in full as it names various natural persons, and this is not the sort of legal blog to name natural persons caught up in litigation unless necessary. This blog is more concerned with the legal issues.

*

THE PARTIES

The applicant for the Order was, of course, the council.

The respondents were four named individuals, but also as a fifth respondent “persons unknown” who are

“intending to

(i) attach flags to highway structures or mark flags on the highway in the county of Oxfordshire,

(ii) harass members of Oxfordshire County Council or

(iii) obstruct or harass employees or contractors of Oxfordshire County Council involved in the removal of flags from highway structures”

The Order is thereby only against the “persons unknown” as three of the four named respondents all gave undertakings to the court on the terms of the injunction, and the fourth respondent indicated that they too would give an undertaking.

An undertaking generally has the same legal consequences for a party as an injunction, and with similar sanctions for breach. A court will often allow a respondent an opportunity to give an undertaking in lieu of an injunction, and that is what happened here. The four named respondents will be as bound legally by their undertakings, as if an injunction was made.

(And giving an undertaking has beneficial costs consequences for the respondent, rather than them refusing and requiring the court to make the respondent to be a party to an Order.)

That the Order was still required despite the undertakings was because of the “persons unknown” element.

*

THE MAKING OF THE ORDER

The Order was made by Mr Justice Dexter Dias of the King’s Bench Division of the High Court, and it was sealed on 23 June 2026.

The Order does not refer to any particular legislation (for example highways legislation) under which the Order is made, and so it may be presumed that it is under the general jurisdiction of the High Court.

And although the claimant is a public body, it appears that the Order was made not by the Administrative Court, but by the (general) King’s Bench Division of the High Court which deals with (general) civil and private law matters.

It is an interim Order, and there is a further hearing listed for 9 July 2026. This means that, in theory, this Order is not the end of the matter and that the Order “holds the ring” (to use the usual phrase) until the claim of the council can be tried. In practice, however, many claims end once an interim Order has been secured.

When making such an interim Order, a court usually has to have regard to the “balance of convenience” of the parties, and here the court says expressly that it found the balance of convenience against “persons unknown”.

*

WHAT IS ORDERED?

Until a trial takes place (which may or may not take place), or until the court orders differently, “persons unknown” (as defined above in a quote):

“shall not:

(a) attach any flag or cause any flag to be attached to any highway structure;

(b) paint or mark any flag on any of the highways;

(c) obstruct the Claimant’s officers or contractors from removing flags from highway structures;

(d) cause harassment, alarm or distress to the Claimant’s members or to officers or contractors of the Claimant who are or have been involved in the removal of flags from highway structures, including the decision to remove them.

(2) Persons unknown (as defined above) shall not encourage any other person to act in away prohibited by [the paragraph above].

If “persons unknown” do any of these things they will be in contempt of court, which may mean imprisonment or a fine, or the seizure of assets. This is set out in the important penal notice on the front page of the Order.

The “highway” and “highway structures” are defined in the Order as follows:

“In this Order (1) references to highways are to highways in the County of Oxfordshire for which the Claimant is the highway authority; (2) “highway structures” means lampposts, lighting columns, street signs, trees, barriers, railings and other physical structures in the highways.”

As such, this Order does not cover the placing of flags on any private property.

The Order does not mention any points about freedom of expression or expressly conduct any balancing exercise under the Human Rights Act. It looks like it was treated as a straight private law claim by the council.

*

HOW ARE “PERSONS UNKNOWN” TO BE BOUND BY THE ORDER?

This raises an obvious question of how are “persons unknown” to be made aware of this Order? The general rule is that a person cannot be bound by an Order unless they have notice of it. This notice can be actual notice or what is called constructive notice.

The Order deals with this as follows (hyperlink added):

Service of the claim form and this Order on persons unknown (the Fifth Defendant)

Pursuant to CPR rr 6.15 and 6.27 the claim form, interim injunction application and this Order shall be served on the person unknown by the following means:

(1) The Claimant shall set up a dedicated webpage on its website giving access to the claim form, particulars of claim, supporting evidence, and this Order.

(2) The Claimant shall notify the groups known as Raise the Colours, Raise the Colours Oxfordshire and Oxfordshire Flying Squad of this Order by email, giving notice that the documents relating to the claim and this Order have been placed online and providing a link to the relevant webpage.

(3) The Claimant shall publish details of the claim and Order on LinkedIn, Bluesky, Facebook, Nextdoor, WhatsApp and the Claimant’s fortnightly newsletter for residents “Your Oxfordshire” and the Claimant’s news page with links to the relevant webpage.

The claim form shall be deemed served on the Fifth Defendant 3 days after steps (1) to (3) above have been completed, which shall be done by 4pm on 24 June 2026.”

(Interestingly paragraph (3) does not include X, formerly Twitter.)

The council does not appear to have set up a dedicated webpage yet, but this blog will add a link to it when it does.

A guidance note to the Order adds:

“Effect of this Order

A Defendant who is an individual (including persons unknown) who is ordered not to do something must not do it himself or in any other way. He must not do it through others acting on his behalf or on his instructions or with his encouragement.

A Defendant which is not an individual (including persons unknown) which is ordered not to do something must not do it itself or by its directors, officers, partners, employees or agents or in any other way.

Parties other than the Claimant and Defendant

Effect of this order

It is a contempt of court for any person notified of this Order knowingly to assist in or permit a breach of this Order. Any person doing so may be sent to prison, fined or have their assets seized.”

And so it is by a combination of the Order and the Council doing what it can to publicise the Order that “persons unknown” are to be bound by the Order.

*

Given this appears to be an Order of the High Court in respect of its general jurisdiction in respect of a general private law claim, it would seem what Oxfordshire County Council has done here could be done, in principle, by any other local authority.

What to know about court orders, injunctions, and super-injunctions

21st July 2025

A general introduction to the coercive powers of the court to order things, and what can be done with those powers

Imagine the polity of the United Kingdom as so many machines.

There is the machine of the Crown, and – from a legal perspective – what comes out are various legal instruments enforceable and/or recognised at law: proclamations, decrees, royal charters, royal warrants, privy council regulations, and so on.

Each instrument following a certain form and even ceremony, with certain ‘abracadabra’ magical wording, and the document exists at law.

And because that document is capable of making things happen, it is called an instrument.

*

There is then the machine of Parliament, and – again from a legal perspective, what comes out are Acts of Parliament.

In a technical way these are a subset of documents from the Crown machine, as an Act of Parliament is not enforceable and/or recognised at law unless it has Royal Assent. It is in this way just another legal instrument signed by the Crown.

But Acts of Parliament can have general, even universal effect, and so are in a category of their own.

Note that other things done by Parliament – such as passing motions and resolutions – do not normally have effect outside of the Palace of Westminster (if at all).

And so when one talks of the sovereignty (or more correctly the supremacy) of Parliament, one usually means the sovereignty (or supremacy) of Parliamentary legislation.

*

And then there is the judiciary machine.

To an onlooker (and indeed many lawyers) the outputs of the judiciary machine are the judgments and sentencing remarks. And indeed the reports of judgments and remarks are central to understanding laws and legal systems around the world.

But.

The main outputs of the judiciary machine are not judgments or sentencing remarks: they are at one or two steps removed.

The main outputs of the judiciary machine are Orders.

(There are other judicial outputs such as writs and summons and warrants.)

It is the Orders that have legal effect, that are enforceable and/or recognised at law.

Judgments and sentencing remarks are all very interesting and informative, but it is the Order that is the thing.

A judgment should explain why the court made one Order instead of another, why a case was disposed of in one way rather than another.

As such, judgments can be integral to understand what has gone with a case, but it is still the resultant Order that is the thing.

Orders are thereby for courts, what Acts are for Parliament, and charters and so on are for the Crown.

They are the things which come out of the judiciary machine, at least from a legal perspective.

*

Orders can take many forms, but the form of Order which comes up most often in the news is the injunction.

An injunction is – very generally – a court Order which tells a person to do a thing or not do a thing, on pain of it being punishable as a contempt of court.

The classic historical-legal theory is that an injunction is there so as to ensure a person acts in accordance with their conscience: to do or not do a thing they ought or ought not to do.

Injunctions usually are either ‘final’ or ‘interim’/’temporary’. The latter are often used by courts to ‘hold the ring’ until a legal matter can be finally disposed of by the court: to keep things in a virtual legal state of suspended animation for the time being.

The normal position is that an injunction can be imposed on a party to litigation.

Here [A] is suing [B] for say breach of contract or an intellectual property infringement, and [A] wants to stop [B] for causing any further damage until the trial.

(Sometimes it may turn out that [B] has been injuncted when [A]’s case does not succeed at trial, and in those situations [A] must make good the damage and costs caused to [B] complying with the injunction. As such injunctions can be double-edged legal weapons. In legal practice, injunctions are the sort of things you ‘don’t try at home’ and should be left to the professionals. Injunctions can cut in unexpected and painful ways.)

Sometimes a party will want a permanent, final injunction – but generally (at least in England) injunctions are a means to an end and the final remedy at court will usually be damages.

A party breaching the injunction faces punishment (and there is a legal debate whether such punishments are criminal as such) which can include imprisonment.

A person guilty of contempt will then be expected – to use a quite lovely legal word – to ‘purge’ their contempt.

*

Injunctions, however, may not only be against a party to legal case.

They can also be granted against third parties.

In England such injunctions are not at all unusual – and the courts have developed all sorts of freezing orders and search orders where third parties caught up in a situation can be obliged to comply with court orders.

Sometimes such injunctions can be made against persons unknown (for example trespassers) or even ‘contra mundum’ (against the world).

Obviously there is practical difficulty in showing a person is aware of such an order, and the normal position is that a person is not bound by an Order unless they have (or should be expected to have) notice of the Order.

That is why injunction notices are tied to fences or emailed to legal departments of newspapers, and so on.

The injunction in the recent Afghan case was applied by the government to be ‘contra mundum’ order:

As a subsequent judgment in the same case described:

If a person has notice of a contra mundum notice then they are as bound by it as any party to the litigation.

An affected third party can have protections built in to the Order – and can also apply to the court to have the Order amended or discharged. But in practical terms the third party has little choice but to comply.

*

There is a further way to super-charge an injunction, by giving it is a special super power (though this is rare for contra mundum injunctions).

A court can turn an injunction into…

…a super-injunction.

In a super-injunction it is a term of the Order that the existence of the Order itself cannot be disclosed.

In the recent Afghan data breach case, there was a super-injunction. A judge in the case described it as follows:

Originally the super-injunction in that case was not published with the raft of documents released last week.

But following a request from this blog, the Order was published.

The “super” element of the Order is at paragraphs 4(b) and (c):

A non “super” version would have 4(a) and no mention of 4(b) in the final sub-paragraph.

If you go to front page of that Order you will see the penal notice, to warn those of the dire consequences of any breach:

Such an Order is thereby not to be taken lightly, and they are not taken lightly by any responsible person.

Super-injunctions were briefly common about 2010 as a means of protecting the claimant when they were suing for the then new tort of misuse of private information, but media and political controversy meant that the courts moved away from granting them.

*

The Afghan data breach case injunction was both a contra mundum injunction *and* a super-injunction.

As such it was an exotic legal creature, the sort which are sometimes speculated about, but rarely spotted in reality.

But even if they are exceptional the components are straightforward:

(1) it was an interim injunction that

(2) was addressed to anyone who had notice of it which

(3) had as one of its terms that the injunction should not be revealed beyond those who had notice of it.

Such injunctions can exist – and some would say that they have their place in exceptional situations.

But one question is whether it was appropriately granted in this situation – and, if so, whether its terms should have been discharged or varied sooner.

And another question is whether in this situation such an injunction stymied legitimate public knowledge and political/media scrutiny of the government by parliament.

For sometimes even the judiciary machine fails to function properly.
