HSF and Mishcon enlisted as legal battle over suspension of Parliament intensifies

Sir John Major (pictured) has instructed litigation heavyweight Herbert Smith Freehills (HSF) as the former Prime Minister looks to join investment manager Gina Miller in a legal challenge against the suspension of Parliament.

HSF disputes partner Andrew Lidbetter has been enlisted to instruct The Rt Hon Lord Edward Garnier QC and Tom Cleaver of Blackstone Chambers, with the pair representing Major as he looks to get behind the existing claim brought by Miller, rather than initiating separate proceedings.

Meanwhile, Mishcon de Reya partners James Libson and Rob Murray have been instructed by Miller.

In a statement, Major said: ‘I promised that, if the Prime Minister prorogued Parliament in order to prevent members from opposing his Brexit plans, I would seek judicial review of his action. If granted permission to intervene, I intend to seek to assist the Court from the perspective of having served in government as a minister and Prime Minister, and also in Parliament for many years as a member of the House of Commons.’

Murray acted for Miller when Mishcon successfully pursued a claim in the Supreme Court that an Act of Parliament was required to trigger Brexit. However, a separate legal challenge against the proroguing of Parliament supported by 75 MPs failed today (30 August) after a Scottish judge temporarily refused to make an emergency order preventing the suspension.

While Miller’s 2017 claim proved successful, she is expected to face an uphill battle in convincing the courts a proroguing of Parliament is unconstitutional. Miller’s case also faces greater time constraints than in 2017, with judicial review a slow process which will have to be expedited. The time pressure will be all the greater as the side that loses the first review will likely appeal.
