The senior judge who ruled against Boris Johnson's suspension of Parliament once declared that Brexit was "likely to be a very onerous task".
In a nother upcoming case, a legal action addressed at Boris Johnson personally seeks to empower the Inner House to write to the European Union requestion an Article 50 extension on the prime minister's behalf.
Boris Johnson is resisting growing demands to recall Parliament after an explosive ruling by Scotland's top court that he had broken the law and misled the Queen by shutting down the Commons for five weeks.
"It is absolutely central to our constitution that the relationship between the Prime Minister and the Queen is one of the utmost confidentiality and the utmost good faith".
He explained: "The normal view of the courts is that it would not be appropriate to rule on the exercise of prerogative power".
"So the long-term significance of this ruling is very important".
"The lower court had said the actions of the executive were "non-justiciable" - meaning they were not to be examined by judges".
As we've said, the current parliamentary session is the longest parliamentary session in nearly 400 years.
It comes after an English court upheld the prorogation, leading to a legal stand-off between both sides of the debate.
But when the case was taken to three appeal judges, they saw it differently.
In another major development Wednesday night, the government refused to publish details of internal discussions about the suspension, or prorogation of the House of Commons despite Members of Parliament (MPs) voted to force the release.
"We have a court saying that the prorogation of parliament is unlawful, null and void", Sturgeon said.
Lord Carloway, the Lord President, said prorogation was sought "in a clandestine manner" when Downing Street knew that 75 MPs and peers were taking the government to court to block it.
I am pleased that Scotland's highest court agrees.
But that does not diminish the effect of the ruling, as the case was against the actions of the Westminister government which, within the devolution settlement, affects the whole of the UK.
"The court agreed it is unlawful to suspend the UK Parliament for the specific objective of preventing Parliament from scrutinising the Brexit process and holding this shambolic Tory Government's extreme Brexit plans to account", she said.
"It is quite extraordinary what the Scottish courts have ruled. Any argument that parliament is "in practice" prorogued is thus spurious".
Although proroguing parliament - or suspending it from sitting - is not unheard of, this time it was seen as different.
Parliamentary sessions normally last a year, but the current one has been going on for more than two years - ever since the June 2017 election.
"The prime minister needs to heed this warning, get MPs back to Westminster and sort out the mess we're in".
