SCOTLAND'S top law officer is seeking to intervene in the court bid to block Prime Minister Boris Johnson's attempts to prorogue parliament.

The chief legal adviser to the Scottish Government has lodged an application to intervene in legal cases brought by Joanna Cherry MP and others at the Court of Session in Edinburgh, and anti-Brexit campaigner Gina Miller's action at the High Court in London.

James Wolffe QC will argue that the UK Government’s prorogation of the UK Parliament prevents scrutiny and represents an abuse of executive power.

The hearing in Edinburgh before Lord Doherty takes place on September 3, and the hearing in London is scheduled for September 5.

Constitutional Affairs Secretary Michael Russell said: “Accountable government is a fundamental principle of our democracy. This attempt to suspend the UK Parliament at such a critical time is a clear attempt to silence opposition and must be resisted.

“The democratic wishes of the Scottish people and the Scottish Parliament should not be allowed to be brushed aside as if they did not matter.”

Cherry's case, supported by 74 other MPs, contends that it is "unlawful and unconstitutional" to prorogue Parliament to avoid further Parliamentary participation on Brexit.

If the Commons is prorogued, it would sharply cut the number of days MPs have to stop Brexit.

Lord Doherty refused a request for an interim suspension or interdict in the case, but moved the hearing forward from Friday to tomorrow.

At the time, Jolyon Maughan QC, of the Good Law project which is backing Cherry’s case, said: "The decision of the Outer House of the Court of Session today - which explicitly declined to express any view on our prospects – just kicks the can a few days down the road.

“We are pleased the Court of Session agreed to advance the full hearing on the lawfulness of the Prime Minister’s attack on Parliamentary sovereignty from Friday of next week to Tuesday.”

A UK Government spokesman said: “As we have set out, the government needs to bring forward a strong domestic legislative agenda and MPs are not prevented from scrutinising our withdrawal from the EU.

“We are glad the court found against the interdict – there was no good reason to seek one, given the full hearing is due to take place next week, and the process of bringing the session to an end will not start until the week commencing 9 September.”
