The UK supreme court ruling against Boris Johnson has been celebrated as a sign of a healthy democracy by senior political figures in Brussels and other EU capitals but sparked fears of further Brexit chaos.
As Lady Hale, the president of the UK’s highest court, read out its unanimous judgment, politicians, officials and diplomats involved in the Brexit talks spoke of their reassurance about the state of the rule of law in the UK.
The decision to prorogue parliament for five weeks in order to avoid parliamentary scrutiny had already provoked criticism by senior politicians in the European parliament, and the court’s confirmation on Tuesday that Johnson’s move was unlawful was welcomed.
Guy Verhofstadt, the EU parliament’s Brexit coordinator, tweeted: “At least one big relief in the Brexit saga: the rule of law in the UK is alive & kicking.
“Parliaments should never be silenced in a real democracy. I never want to hear Boris Johnson or any other Brexiteer say again that the European Union is undemocratic.”
The European parliament’s speaker, David Sassoli, said: “Important decision from UK Supreme court to rule prorogation of Parliament as unlawful.
“Any Brexit agreement needs to be approved by both UK and EU Parliament, so proper democratic scrutiny on both sides of the Channel is essential.
The chair of the Bundestag’s foreign affairs committee, Norbert Röttgen, who is a senior member of Angela Merkel’s CDU party, expressed his satisfaction at the judgment.
He said: “It is not my place to comment on judicial proceedings in Britain. But as a fellow MP I do feel the need to express my joy and solidarity with British parliamentarians.”
A former head of the EU council’s legal service, Jean-Claude Piris, tweeted: “It gives me good and emotional feelings too.
“It was so sad to see this great country at the risk of being led to no longer respect the principles and values upon which its democratic institutions have been built over centuries.”
Asked by reporters whether Johnson should resign, the Irish taoiseach, Leo Varadkar, said the issue was an “internal matter” for the UK. “Whoever is prime minister of the United Kingdom is somebody we’re going to work with,” he said. “It’s not for us to decide who the prime minister of the UK is.”
Sources said the impact on the talks in Brussels was not clear, although there was a consensus that it made it less likely Johnson would be able to force through a no-deal Brexit on 31 October now that parliament had further opportunities to act.
The prime minister is seemingly constrained by the Benn Act, which would instruct him to seek an extension if a deal is not agreed with the EU and backed by the Commons, but Johnson had suggested he would find a way around the law.
One EU diplomat said: “Another domestic in this long Brexit saga. Parliament hasn’t been able to formulate a position in the last three years so why would they suddenly now?
“Without decisive action their government is driving this process off the cliff. But seeing as Brexit was about the sovereignty of parliament it was bewildering that government moved to suspend it. So much about this process is contradictory and utterly mind-blowing.”
The court ruling immediately raised questions about whether British officials would attend talks in Brussels, which were expected to continue on Wednesday. The UK had also been hoping for a major shift in the EU’s position on ditching the Irish backstop this week but the prospects of such a move always looked vanishingly small.
An EU source spoke of growing frustration in Brussels. “Are the chances of an extension request probably very high? Yes. And has the court’s judgment made the chances higher. Cautiously yes. And is the EU banging it’s head against a brick wall saying: when is this going to stop? Absolutely.”
Fabian Zuleeg, the chief executive of the European Policy Centre thinktank, tweeted: “Conclusions? 31 October no deal unlikely unless Boris Johnson is willing to break law and won’t be stopped.
“So Boris Johnson only has two real options: resign and fight election on clear no-deal stance or make deal, capitulating in negotiations. Former looks more likely but unlikely to bring resolution.”
When asked whether the ruling threw doubt on Johnson’s credibility in the negotiating room, a spokeswoman for the European commission said: “We have all seen the news but it is not for us to comment on the internal constitutional matters of the United Kingdom. Our interlocutor is the United Kingdom government and that remains the case. All other judgments I leave to you.”
