COMMENTS from the SNP and a co-leader of the Scottish Greens about the legitimacy of the Scottish Parliament legislating for indyref2 without Westminster’s approval have justified the legal bid to prove just that, according to the campaigner spearheading the case.

Martin Keatings, who is behind the People’s Action on Section 30, was speaking after the Greens’ Patrick Harvie wrote in The National yesterday that if you are going to have a referendum, you want everyone to accept the rules of the game.

“It would clearly not be legitimate for them to dig their heels in and say no, never, no way,” said Harvie. “So I think the proposal to say if they continue to stick to that position, we will test the matter in courts, we will take forward the legislation and test the ability of the Scottish Parliament to legislate without a Section 30 is a perfectly legitimate approach to take.”

In January, The National told how the SNP had said in its new plan for indyref2 that if it wins the May election and there is a pro-independence majority, it will again ask for a Section 30 order – in the same way as for the 2014 referendum.

However, if that were refused the Scottish Government would press ahead and it would be up to the UK Government to either “agree that the Scottish Parliament already has the power to legislate for a referendum” or “agree the Section 30” or “take legal action to dispute the legal basis of the referendum and seek to block the will of the Scottish people in the courts”.

Keatings said supporters of his People’s Action on Section 30 had faced resistance from “every angle”, but now Scotland’s two pro-indy parties were confirming that “whether or not it is legitimate for Holyrood to legislate for a referendum without a Section 30 could be called into question”.

He said the issued had caused some “gnashing” of his teeth as the parties were now advocating spending what would be “vast sums of money” on what is currently a “live” case before Scotland’s highest court.

“Each and every one of them was invited to participate in the case, but I guess it’s easy to do it twice when you have taxpayers money to waste,” Keatings wrote in a Twitter thread.

“Putting aside the fact that I am now going to have to visit the dentist due to the teeth grinding, we all know what this means with these statements from both parties – the entire People’s Action on Section 30 was completely justified.

“It would be funny if it were not so serious.”
