Boris Johnson, Frontrunner to Replace Theresa May as British PM, Wins Court Challenge over Misconduct Summons

London: Former foreign minister Boris Johnson, the frontrunner to replace Theresa May as Britain's prime minister, on Friday won his bid to block a lawsuit accusing him of knowingly lying during the Brexit referendum campaign.

The decision removes a hurdle for Johnson in his leadership bid, with his lawyers persuading a London court that the private prosecution was "politically motivated and vexatious".

They asked the High Court to throw out a judge's decision last month to allow a summons ordering Johnson to appear in court over allegations of misconduct in public office, arguing the decision had "erred in law".

"We are quashing the decision of the district judge to issue the summonses," Michael Supperstone, one of two High Court judges hearing the case, said following a hearing Friday, at which Johnson was not present.

The case, brought by businessman Marcus Ball in a crowd-funded initiative, concerned Johnson's claim that Britain sends 350 million pounds ($440 million) a week to the European Union.

While this was Britain's gross contribution, the net figure accounts for a budget rebate from the EU as well as payments to Britain's public sector from the EU budget, and is substantially less.

The official Leave campaign emblazoned the controversial figure on the side of its touring bus during the 2016 EU referendum, while Johnson and other Brexiteers repeatedly trumpeted it campaigning.

Ball, 29, who has crowdfunded more than $300,000 through an online campaign to bring the case, told reporters ahead of the hearing he believed in "the merits of it".

In a written ruling on May 29 district judge Margot Coleman had agreed that was there was a proper case to issue a summons.

But Adrian Darbishire, Johnson's lawyer, asked the High Court Friday to throw out the prosecution because it was political in nature.

"The only rational conclusion which could be reached was that the prosecution was politically motivated and, therefore, vexatious," he said.

The two-judge panel agreed.

"It was the conclusion of the court that we were persuaded by Mr Darbishire," said judge Anne Rafferty.

"This quashes the summons," she said on revealing their ruling.

Johnson on Monday launched his campaign to succeed May as Conservative leader.
