Five judges, one proscription: the political cost of banning Palestine Action

Five senior judges sat in Court 4 of the Royal Courts of Justice on 16 June 2026 and, by the account of one climate lawyer who watched them do it, finished the work the Home Office began in the summer of 2025. The hearing, a five-day contempt proceeding brought under anti-terrorism laws, was supposed to settle a narrow procedural question. It has, instead, reopened a much wider one: what does a democratic state owe the people it has declared terrorists?

The question lands hardest on the judiciary itself. The proscription of Palestine Action — the campaign group that, according to a 2025 High Court ruling, directs criminal damage at sites it ties to the UK–Israel arms chain — has always been a politically combustible act wrapped in legal language. That it was the Home Secretary who placed the group on the list, and that the body now weighing consequences for the lawyers who questioned that placement is the same institution that approved the listing, makes the optics sharper. Defend Our Juries' director Tim Crosland, the climate barrister whose contempt case prompted the five-day hearing, has now argued in public that the judges who sat through it have done lasting damage to their own reputations.

How the case got here

Palestine Action was proscribed in July 2025 under the Terrorism Act 2000, making membership or support for the group a criminal offence carrying a sentence of up to 14 years. The legal basis, as the High Court set out in the autumn of 2025, rested on a series of incidents the group either directed or claimed — most prominently the break-in at a Bristol defence-involved site earlier that year, in which activists sprayed aircraft components with red paint and caused damage reported in the low seven figures.

Defend Our Juries, a campaign collective that has framed itself as a legal-defence outfit for climate and pro-Palestine direct-action defendants, treated the listing as a category error. The argument, rehearsed in protest statements and in court filings throughout 2025, was that criminal damage — even criminal damage of considerable cost — is not terrorism, and that the state had used anti-terror powers to short-circuit the political process. Crosland became the public face of that argument. The contempt hearing now under way in June 2026 stems from statements he made about the listing and about the judges considering challenges to it.

That the contempt case is being heard by five senior judges rather than the usual one is itself unusual. The composition, as Skwawkbox reported on 16 June 2026, was read by supporters as a signal that the court wanted the question of Crosland's conduct — and, by extension, the legitimacy of his criticisms — settled with the weight of a divisional court behind it.

What Crosland actually said

The most politically loaded claim attributed to Crosland in the run-up to the hearing is that the judges have "tarnished" themselves. The framing is deliberate. It inverts the normal direction of contempt jurisprudence, in which the court weighs whether the speaker has impugned its dignity; here, the speaker is arguing that the court has impugned itself by lending its authority to a proscription that, in his telling, criminalises dissent rather than violence.

Two things are worth keeping separate. The first is whether, as a matter of UK contempt law, statements of the kind Crosland is reported to have made cross the line from criticism into interference. The second is whether the underlying critique of the proscription has merit on its own terms. The first is a question for the five judges now sitting. The second is the one that the proscription was, in part, designed to keep out of mainstream political conversation — and the reason it has refused to stay out.

It is also worth noting what Crosland has not claimed. He has not, on the public record available to this publication, denied the criminal damage at the Bristol site. He has not argued that direct action is, in principle, beyond the reach of the criminal law. The argument has been narrower: that the wrong statute was used, and that using it carries a democratic cost that ought to be visible.

The case the Home Office will not have to make

The Home Office's strongest legal move, after the 2025 High Court judgment, was to let the listing stand and wait. Proscription orders are reviewed internally, but the political cost of defending one in open court is high. Every confirmation hearing risks a witness box in which ministers are asked to distinguish, on the record, between a group that broke into a facility and a foreign-terror organisation whose members have killed civilians. The government has chosen, so far, not to put that distinction to a public test.

The result is an asymmetry. Palestine Action's defendants have argued their case in magistrates' courts, in the High Court, and now, indirectly, in a five-judge contempt tribunal. The state has argued its case largely in written grounds and in Home Office statements. The legal outcome of the contempt hearing is therefore likely to be the most public judicial weighing of the proscription's consequences to date — even though the listing itself is not the order being made.

It is also, by design, a hearing about a lawyer rather than about a movement. Crosland is the named respondent. Palestine Action is not. That procedural narrowing is what makes the five-judge composition significant: it concentrates the political oxygen onto a single figure whose conduct, and not the underlying proscription, is the matter before the court.

What is actually at stake

The narrowest reading of the hearing is that a barrister will, or will not, be found in contempt for statements made about judges. A wider reading is that the court is being asked, in effect, to certify the political boundary between permissible criticism of a proscription and impermissible interference with it. A still wider reading is that the judges have been put in the position of being the public defenders of a contested listing that ministers have chosen not to defend at a political level.

The reputational cost Crosland has identified is real on that wider reading. Senior judges in the UK are not elected. Their authority depends on the perception that they apply the law without regard to the political weather. When a proscription is politically controversial — and the Palestine Action listing has drawn sustained criticism from civil-liberties organisations, from sections of the legal profession, and from a parliamentary minority — the bench inherits some of the controversy by association, whether or not the underlying judgment is sound.

Crosland's argument, translated into plain terms, is that the judges cannot hear cases that flow from a politically contested proscription without becoming, in the public mind, parties to that contest. The five-judge composition makes that inheritance harder to disclaim. It is an argument that can be rejected on the law while still leaving a residue in the court of public opinion — which is, in part, why the contempt hearing has drawn attention well beyond the small audience that usually follows procedural hearings in the Royal Courts of Justice.

What we do not know

Two things remain genuinely uncertain at the time of writing. The first is the judgment itself: the five judges have reserved their decision, and the timetable for its handing-down is not public. The second is the broader political response. The government has so far declined to revisit the listing. A finding against Crosland would, in all likelihood, be used by ministers as further confirmation that the proscription was correctly applied. A finding in his favour would put the question back onto the political agenda in a form ministers have so far avoided.

What the sources do not specify, and what no amount of inference can supply, is how the panel will resolve the tension at the heart of the case. They have been asked to weigh a critic's right to be rude about a politically sensitive decision against the court's interest in not being made a tool of political combat. The law has tools for that weighing. The politics of it will outlive whichever way the tools are applied.

This publication treats the proscription of domestic protest groups as a matter of democratic substance, not a technical legal footnote. The five-judge composition made the hearing a national story; the judgment, when it comes, will be a national test.
