A five-week closure, approved in August
The ceremony that ended the session did not pass quietly. Opposition MPs interrupted it. There were scuffles, and bursts of song, as the United Kingdom Parliament was prorogued for five weeks . From the floor of the House the scene looked like a protest against a ritual. It was also the public last act of a decision taken earlier, and taken deliberately. Boris Johnson had approved a plan to shut down Parliament in mid-August . He had asked the attorney general, Geoffrey Cox, whether Parliament could be shut down for five weeks starting on 9 September . By the time the commissioners arrived, the closure was no longer a rumour of the Brexit autumn. It had a start date, a length, and the prime minister's approval.
The claim that would eventually reach the Supreme Court was sharper than a complaint about the length of a recess. The court was to hear that Johnson had acted unlawfully in advising Queen Elizabeth II to suspend Parliament for five weeks in order to stifle debate over the Brexit crisis . A prorogation of that span is not an adjournment in the ordinary diary of the House. It ends a session. The chamber stops. The weeks in which a no-deal departure was being argued over in public were, on this plan, weeks in which Parliament would not be sitting to argue them.
John Bercow had already drawn that distinction in political language, before any court had ruled. He said he would fight to stop Johnson proroguing Parliament so as to force a no-deal Brexit without the consent of MPs . The Guardian reported the vow in the Speaker's own register: he would "fight with every breath" to stop the prime minister closing Parliament for no deal . A Speaker cannot veto the Crown's power to prorogue. He can refuse to treat a long closure, timed to a constitutional crisis, as a neutral piece of ceremony. That refusal would matter twice: once as a warning, and later as a practical question about what the House should do if a court held that the ceremony had been a nullity.
Gina Miller's lawyers did not wait for the commissioners. They applied to the High Court for a judicial review of Johnson's plan to prorogue Parliament . In Scotland, a judge refused to order a temporary halt to the shutdown ahead of a full hearing . The refusal of an interim order is not a decision on the merits. It did mean that the plan approved in mid-August, and put to the attorney general as a five-week closure from 9 September, was not stopped at the door . Parliament was prorogued. The scuffles and the song were the record of a House being closed while the legality of the closing was still in argument .
That order of events is the spine of the cases that followed. A prime minister asks his attorney general about a five-week shutdown . He approves the plan in mid-August . A claimant seeks judicial review . An interim ban is refused . The ceremony proceeds, and is interrupted . Only then do the senior courts, in different parts of the United Kingdom, say what they think the law allows a prime minister to do when he advises the Queen to prorogue. The Supreme Court would later describe the territory as difficult. The difficulty was already visible in the sequence: a power exercised in the Queen's name, a political purpose alleged by the challengers, and a Parliament that had been sent away before the argument was finished.
Elsewhere in the same crisis, the courts were being asked adjacent questions and were declining them. A Belfast High Court dismissed claims that a no-deal Brexit and a hard border would damage the Northern Ireland peace process . That was not a ruling on prorogation. It was a reminder that judges were already sorting which parts of the Brexit argument they would hear and which they would not. The prorogation cases would force that sorting into the open, and the courts would not sort it the same way.
English judges and Scottish judges give opposite answers
The first full answers did not agree. Three senior English judges declared that the prime minister's decision to prorogue Parliament for five weeks was a political matter and not reviewable by the courts . On that view, the advice to the Queen sat in a territory the judges would not enter. The length of the closure, the proximity of the Brexit crisis, the Speaker's warning, the application brought by Gina Miller's lawyers: none of it, in the English account reported by The Guardian, converted a political judgment into a legal one . The challenge was rejected because the subject was said to be the wrong kind of subject for a court.
Scotland's highest court reached the opposite conclusion. It ruled that the five-week suspension of Parliament was unlawful . The same closure, the same prime minister, the same advice to the Crown: unlawful in Edinburgh, and, on the English account, not a matter the courts could examine at all in London . The BBC reported the Scottish ruling as a finding that the suspension was unlawful, and reported the case as it moved towards the Supreme Court as "a difficult question of law" . The difficulty was not a matter of emphasis. It was a conflict about the threshold. If the English judges were right, the Supreme Court had little to decide beyond confirming that the courts should stand back. If the Scottish judges were right, a prime minister's advice to the Queen on prorogation was already inside the law, and the five-week span had crossed a line.
The record of what the English courts held is not itself unanimous in the sources. The Guardian's account is that three senior English judges rejected the challenge as political and not reviewable . A separate report, of proceedings cited as EWCA Civ 227, is given in the material as a holding by the Divisional Court of the Queen's Bench Division that the prime minister's decision to prorogue Parliament was unlawful . Those two accounts cannot be folded into a single sentence without pretending the sources agree. They do not. One says the English judges refused to review the decision . The other is presented as a holding that the decision was unlawful . The disagreement is part of the story of the case, not a footnote to be smoothed. What can be said without choosing between them is narrower, and more important: by the time the appeals were ready, the United Kingdom did not have one judicial answer to the five-week prorogation. It had at least two, and the sources do not even settle the English answer in the same terms.
The Scottish path had its own stages, and they should not be collapsed. A Scottish judge had refused a temporary ban on the shutdown ahead of the full hearing . Scotland's highest court then ruled the suspension unlawful . An interim refusal and a final finding of unlawfulness are not a contradiction. They are a timetable. The plan was not frozen. Parliament was prorogued . The highest court in Scotland then held that the suspension should not have happened . The practical consequence of that finding, while the English position remained contested in the sources, was that the law of the United Kingdom on this point was split along the border until a single court could speak for the whole jurisdiction.
That is why the appeals mattered as procedure, not only as politics. The Supreme Court was hearing appeals on the lawfulness of Johnson's decision to suspend Parliament . It was also, on the account given before the hearing, to consider a claim that he had acted unlawfully in advising the Queen to suspend Parliament for five weeks to stifle debate over the Brexit crisis . The alleged purpose was part of the case the court had agreed to hear. So was the fact of the advice itself: not a ministerial statement in the House, but advice to Queen Elizabeth II, whose formal act had sent Parliament away . A court that decided the matter was non-justiciable would never reach the purpose. A court that decided the advice was unlawful would have to say what that did to the prorogation the Queen had been advised to order.
The hearing, and the question the court was willing to take
The BBC's framing of the hearing was restrained, and it is worth keeping. The suspension case was "a difficult question of law" . That phrase does not decide the case. It does mark what the court was prepared to treat as law. A question of law can be difficult and still be a question for judges. The English approach reported by The Guardian had been that the difficulty was of a different kind: political, and therefore not for them . By listing the appeals and describing the issue in legal terms, the coverage of the Supreme Court hearing already signalled that the threshold fight would be reopened rather than inherited .
The hearing also brought in argument from outside the two lead claims. A former prime minister's lawyer argued against the prorogation . The sources do not, in the material given here, set out that argument chapter by chapter, and it would be wrong to invent its content. What the fact of the intervention shows is the width of the audience the case had acquired by the time it reached the highest court. This was not only Miller's application for judicial review of a plan , and not only the Scottish proceedings that had produced a finding of unlawfulness . It was a hearing at which the lawfulness of a prime minister's advice to the Queen was being contested in public, with a former prime minister's lawyer on the side of the challenge .
The political context of that hearing is attested, and it is not subtle. MPs had passed a backbench amendment, by a margin of 41 votes, to block any future government's attempt to prorogue Parliament in order to ensure a no-deal Brexit . The amendment is a parliamentary fact, not a judicial one. It shows that the House itself had tried to legislate a constraint on the very use of prorogation that the challengers said this closure represented. A margin of 41 is not a landslide. It is a majority. It meant that a government contemplating a shutdown to lock in no deal would face not only litigation but a recorded vote of the House against that device . The Supreme Court was not being asked to enact that amendment. It was being asked to decide whether this particular advice, for this particular five-week period, was lawful .
Bercow's earlier vow sat in the same political frame. He would fight with every breath to stop Johnson closing Parliament for no deal without MP consent . The amendment and the Speaker's warning were different instruments. One was a vote. The other was a promise from the chair. Neither was a judgment. Together they describe a Parliament that did not accept the closure as routine, and a litigation that arrived at the Supreme Court with that non-acceptance already on the record .
There is a temptation, looking back from the ruling, to treat the hearing as a prelude whose ending was obvious. The sources do not support that reading. They support a court taking a question it called difficult, in appeals from courts that had not agreed, on facts that included an approved plan, a refused interim order, a completed ceremony, and an alleged purpose of stifling debate . The difficulty was structural. Prorogation is a power exercised by the Crown on advice. If every such act is political and immune, the five-week closure could not be judged, whatever its timing. If the courts may look at the advice, they have to say how far looking goes: into motive, into effect, into the length of the silence imposed on the House. The Scottish court had crossed that line and found unlawfulness . The English judges, on one attested account, had refused to cross it . The Supreme Court had to say which approach the constitution would live with.
The ruling of 24 September: unlawful, void, of no effect
The Supreme Court ruled that Johnson's advice to Queen Elizabeth II to prorogue Parliament was unlawful . It ruled, in the words that fix the legal consequence, that the advice to prorogue Parliament for five weeks was unlawful, void, and of no effect . The nullification is dated. The Supreme Court nullified the prorogation on 24 September 2019 . The law report is [2019] UKSC 41 . Those are the anchors. Everything said about the ruling in this piece has to be traceable to them, and to the way the sources frame what the court did.
"Unlawful" is a finding about the advice. "Void" and "of no effect" are findings about the consequence . The court did not, on the sources, merely criticise the prime minister and leave the closure standing as a flawed but completed act. It held that the advice was of no effect, and it nullified the prorogation . A session that had been ended by ceremony was, in law, not ended. The weeks in which Parliament had been treated as prorogued were weeks in which, on this ruling, the prorogation had not happened. That is a stronger remedy than a declaration that a minister misjudged a political call. It reaches back into the formal act and empties it.
The Hansard Society's account of what Parliament then had to do procedurally reaches for an image that matches that emptiness. Its title puts the point as a picture of the commissioners having walked into Parliament with a blank sheet of paper . The image is the Society's framing of the procedural problem, and it should be read as that: an account of how a legislature handles a judicial nullification, not a fresh finding of fact about what was written on any document. If the advice was of no effect, the ceremony that carried the advice into the chamber had nothing lawful to communicate . The House had not been lawfully sent away. The practical question, which the Society's piece takes up, was how the procedural record should be made to say so .
Legal commentary immediately asked what kind of adjudication this was. A leading public-law analysis framed the judgment in Cherry and Miller as raising the possibility of a new approach to constitutional adjudication . The source poses that as a question, and the question should stay open. The judgment held the advice unlawful and the prorogation void . Whether that holding marks a new method — a court more willing to examine prime ministerial advice to the Crown, more willing to treat effect on Parliament as a legal limit — is the argument the commentary opens, not a fact the ruling itself announces in the material here . What can be said is that the court did not adopt the stance, attested of the three senior English judges, that the decision was political and not reviewable . It reviewed the advice. It found it unlawful. It stripped it of effect .
The ruling also settled, for the United Kingdom, the split that the hearing had been convened to resolve. Scotland's highest court had already called the suspension unlawful . The Supreme Court agreed with that destination, and it did so in terms that bound the advice and the prorogation, not only the Scottish proceedings . The English rejection of the challenge, as The Guardian reported it, did not survive . The conflicting account of an English holding of unlawfulness, if that is what EWCA Civ 227 is taken to record, was overtaken by a single judgment of the highest court . After 24 September 2019, the argument about this prorogation was no longer an argument between jurisdictions. It was an argument about what the Supreme Court had done .
The personal and political object of the ruling is equally plain in the sources, and should be named without embroidery. The advice was Johnson's . The Queen who received it was Elizabeth II . The period was five weeks . The case names that frame the event are Miller's claim against the prime minister and Cherry's claim against the Advocate General for Scotland. Miller's lawyers had applied for judicial review of the plan . The Supreme Court heard the appeals and decided them . The result was not a rebuke left in the air. It was a nullification, on a dated day, of a prorogation that had already been carried out .
Parliament reconvenes, and the political argument turns on the court
The Speaker's response was operational. John Bercow announced that the House of Commons would reconvene on Wednesday morning, following the ruling that the suspension was unlawful . The announcement closed the gap between a legal nullity and a sitting chamber. If the prorogation was of no effect, the House had to be brought back, and the Speaker said it would be brought back at the start of the next sitting day the announcement named . MPs were to return immediately in the wake of the ruling . The weeks of shutdown, protested at the ceremony with scuffles and song, were cut short not by a change of government policy but by a judgment .
Bercow's Wednesday announcement sits against his earlier vow, and the two should be read together without being confused. Before the ruling, he had said he would fight to stop a prorogation aimed at forcing no deal without MP consent, and he had been reported as ready to fight with every breath . After the ruling, the fight he had described became a direction to the House: come back . A Speaker does not implement a Supreme Court judgment by rhetoric. He implements it by saying when the chamber sits. The sources record that he said Wednesday morning . They do not record, here, the text of any statement beyond that announcement and the earlier vow. The constitutional fact is the reconvening itself.
The political reply was not confined to the Speaker. Jacob Rees-Mogg claimed that the Supreme Court had launched a "constitutional coup" . The attorney general slapped that claim down . The exchange matters because it is the argument over the ruling conducted inside the government, not outside it. One minister, on this report, treated a finding that advice to the Queen was unlawful as an assault on the constitution by the court . The attorney general — the same office Johnson had approached when he wanted to know whether Parliament could be shut for five weeks from 9 September — rejected that characterisation . The sources do not set out the attorney general's reasoning in full. They do establish the split: coup, in Rees-Mogg's claim; a slap down of that claim, from the law officer .
That split is the political twin of the judicial split the Supreme Court had just closed. Before 24 September, English and Scottish courts had not agreed on whether the closure was even reviewable, still less on whether it was unlawful . After the judgment, ministers did not agree on whether the court's answer was a coup or a holding the government had to accept . The attorney general's intervention is the more consequential of the two, because it came from the office that advises the government on the lawfulness of its acts . A law officer who will not defend the charge of a constitutional coup is telling the government, in public, that the judgment is not to be treated as an illegitimacy. The prime minister's advice had been found void . His attorney general would not join a minister in calling the court that said so a usurper .
The amendment already passed by MPs belongs in this political aftermath even if the sources do not date it against the judgment. By a margin of 41 votes, the House had sought to block any future government from proroguing Parliament to ensure a no-deal Brexit . The Supreme Court had dealt with one prorogation, and had nullified it . The amendment was aimed at the device in general: not this advice to this Queen, but any later attempt to use prorogation to lock in no deal . Between them, the judgment and the vote describe two different limits. One is judicial, retrospective, and specific to advice that was void . The other is parliamentary, prospective, and aimed at a purpose . A government that lost in court on 24 September still faced a House that had voted, by 41, to stop the same kind of shutdown being used again for that end .
The immediate picture, then, is of a chamber returning and a government divided about what the return meant. MPs were to be back on Wednesday morning . The prorogation they were returning from had been declared of no effect . A senior minister called the declaration a coup; the attorney general would not have it . The Speaker who had promised to fight the closure was the Speaker who named the morning the House would sit again . None of that required a new statute. It required the judgment to be treated as law. The argument that began the moment it was treated as law was about whether a court may do what this court had done.
What the judgment settled, and what it left open
The judgment settled the status of this prorogation. Johnson's advice to the Queen was unlawful . It was void and of no effect . The prorogation was nullified on 24 September 2019 . Parliament's suspension for five weeks did not survive as a lawful act . The House of Commons was to reconvene . Those propositions are corroborated across the sources, and they are the holding. A reader who wants the ratio in a sentence can stop there, and can find it in the law report [2019] UKSC 41 .
What the judgment did not settle is visible in the commentary and in the politics that followed, and it should be stated with the same care. Public-law analysis asked whether Cherry and Miller marked a new approach to constitutional adjudication . The question is not answered by the fact of the ruling. A court can decide one advice was unlawful without publishing a general theory of when prime ministerial advice to the Crown will be reviewable. The sources here do not supply that general theory in the form of extracted principles, and it would be a fabrication to invent one. The open question is the one the commentary actually poses: whether the method — reviewing the advice, weighing a five-week silence against the Brexit crisis the challengers said it was meant to stifle — is a new approach, or the application of older limits to an extreme use of an old power .
A second unsettled question is whether the ruling travels. A chief justice of the Canadian Federal Court questioned the stance that the United Kingdom ruling does not apply to a prorogation lawsuit . The sources given here do not describe that Canadian case, and this piece will not invent its parties or its facts. What contributes is the argument about reach. A holding that advice to prorogue was unlawful, void and of no effect is a holding about the United Kingdom constitution . Lawyers elsewhere, faced with their own shutdowns of legislatures, were already asking whether the stance of non-application could be maintained . The chief justice's question is not a finding that the UK ruling governs Canada. It is a refusal to treat non-application as obvious . The judgment's authority inside the United Kingdom was settled on 24 September . Its authority as a persuasive account of prorogation was, on this evidence, immediately in dispute beyond the United Kingdom .
A third open front is domestic, and it is political rather than judicial. Boris Johnson, the prime minister whose advice had just been nullified, was reported to be planning radical changes to the United Kingdom constitution . The source states the plan. It does not, in the material relied on here, itemise the changes, and they will not be invented. The relevance of the report is the sequence. A prime minister loses a case about the outer limit of advice to the Queen . He is then reported to be contemplating radical constitutional change . Whether those changes were conceived as a response to the judgment, or as a wider project that happened to coincide with it, is not established by the sources. What is established is that the person found to have given unlawful advice was, in the same season of argument, associated with a programme of constitutional alteration . A court can void a prorogation. It cannot, by that voiding, freeze the constitution the government will try to rewrite afterwards.
The courts' own record, read across the whole set of cases, is a warning against treating 24 September as the moment complexity ended. A Scottish judge had refused a temporary halt . Scotland's highest court had then found the suspension unlawful . Three senior English judges, on The Guardian's account, had called the decision political and not reviewable . Another report is offered as an English holding of unlawfulness . A Belfast court had dismissed a different claim, about no deal, the border and the peace process, rather than about prorogation . The Supreme Court then unified the prorogation question for the United Kingdom and nullified the closure . The unity is real. It is also recent, and it sits on top of a set of refusals, findings and dismissals that do not all point the same way . Anyone who says the constitution "spoke" in a single voice through the autumn of 2019 is describing the last judgment, not the path that produced it.
The path is worth keeping in view because it shows what was hard about the case, in the sense the BBC used when it called the question difficult . The hard part was not finding a villain in a ceremony. The hard part was deciding whether a court may examine advice given to the Queen, and what follows if the advice is found wanting. The English answer, in one attested version, was that the court may not examine it . The Scottish answer was that the suspension was unlawful . The Supreme Court's answer was that the advice was unlawful, void and of no effect, and that the prorogation fell with it . Once that answer was given, the procedural consequence was immediate: a blank sheet, in the Hansard Society's image, where the commissioners' authority to close the session had been thought to stand, and a Wednesday morning on which the Commons would sit again .
There is a further restraint the sources impose, and a magazine account should observe it. They do not record the vote inside the Supreme Court. They do not set out the paragraphs of the judgment beyond the holding that the advice was unlawful, void and of no effect . They do not quote the Queen, or Cox's advice, or the reasons Rees-Mogg gave beyond the phrase "constitutional coup", or the reasons the attorney general gave for rejecting it . They do not specify which radical constitutional changes were planned . A feature that filled those silences with famous details would be writing a different, better-sourced story than the one these clusters support. The story they do support is already large enough.
It is the story of a five-week shutdown, approved in mid-August, tested on the attorney general as a closure from 9 September, challenged by Miller's lawyers, left standing when a Scottish judge refused an interim ban, carried out in a ceremony that opposition MPs interrupted with scuffles and song, condemned as unlawful in Scotland, treated as non-justiciable by three senior English judges on one account, and then nullified by the Supreme Court on 24 September 2019 . It is the story of a Speaker who said he would fight with every breath, and who then named Wednesday morning as the moment the House would return . It is the story of an amendment passed by 41 votes to stop future prorogations aimed at no deal, and of a minister who called the judgment a coup and a law officer who would not . It is the story of a commentary asking whether constitutional adjudication had changed its approach, and of a Canadian chief justice unwilling to accept that the ruling stopped at the water .
Held against that record, the ruling is both narrower and more severe than the political slogans around it. It is narrower because it is a decision on one advice, one five-week period, one prorogation, not a code for every future crisis . It is more severe because "of no effect" does not leave the closure wounded but standing . The commissioners' walk, the interrupted ceremony, the weeks of absence: in law, after 24 September, they did not close Parliament . The House came back because the court said it had never lawfully left . That is the fact the sources corroborate. The disputes they leave standing — what the English courts held before the appeal, whether the method was new, whether the ruling applies elsewhere, what constitutional changes the prime minister intended — are real disagreements, and they are not resolved by repeating the holding more loudly .
The constitution that emerged from Cherry and Miller was therefore not a settled settlement. It was a judgment with a date, a nullification with a procedural aftermath, and a political class already arguing about whether the court had saved Parliament or seized it . The prime minister whose advice was void was still prime minister, and was reported to be planning radical constitutional change . The courts that had divided were now bound by a single ruling, but the sources still do not agree on how to describe what the English courts had said on the way . The legislature that returned on Wednesday morning had already voted, by 41, to constrain the next attempt . And outside the United Kingdom, a chief justice was questioning the idea that none of this applied to the next prorogation lawsuit .
What remains, after the slogans are set aside, is the sequence the clusters actually sustain. Advice was given to the Queen. Parliament was sent away for five weeks. The courts split. The Supreme Court held the advice unlawful, void and of no effect, and nullified the prorogation on 24 September 2019 . The Commons was called back . The argument about what that means for the constitution did not end when the judgment was handed down. On the evidence of these sources, it began there.
