UK Supreme Court Told Boris Johnson is 'father of Lies'

London, Sep 18 (AFP) Prime Minister Boris Johnson is the "father of lies" who shut down the mother of parliaments in the run-up to Brexit, Britain's Supreme Court heard Wednesday.

In the second of three days of highly-charged arguments over whether Johnson's advice to Queen Elizabeth II to suspend the legislature was unlawful, Britain's highest court was told that his move was destroying parliamentary democracy.

The lawyer representing around 75 parliamentarians who challenged Johnson's actions said the premier had unlawfully abused his power by closing parliament for five weeks until October 14 -- with Britain due to leave the EU on October 31.

One might think that a government "would engage solely in high politics as opposed to low, dishonest dirty tricks but I'm not sure we can assume that of this government," lawyer Aidan O'Neill said.

"The mother of parliaments is being shut down by the father of lies. Rule that this prorogation is an unlawful abuse of power," O'Neill told judges. "Enough is enough."

Johnson, who took office in July, says he prorogued, or suspended, parliament to open a new session with a fresh legislative agenda.

His opponents claim he did so to silence opposition to his plans to take Britain out of the EU on October 31, with or without a divorce deal with Brussels.

The Supreme Court is hearing appeals against two conflicting lower court decisions.

Scotland's highest civil court found the suspension was unlawful, but the High Court in England said it was not a matter for judges to intervene in.

The government's lawyer told the Supreme Court that parliament had been debating Britain's exit from the European Union for three years since the 2016 referendum vote to leave.

James Eadie argued that if MPs had needed more time, they had the opportunity to legislate before Johnson suspended their sitting on September 10.

"If the basic attack is this was improper purpose, motivation or effect, because it was designed to stymie parliament, we respectfully submit: that is unsustainable," Eadie said.

He said parliament had previously passed laws on prorogation, but there was no law relevant to the case and so England's High Court was right that prorogation was not something the judiciary could intervene in.

Eadie said any decision to prorogue parliament was "inherently and fundamentally political in nature" as it concerned managing the government's legislative agenda, curtailing parliamentary debate and deciding on when it might be appropriate to end a sitting.

"This is, we submit, therefore the territory of political judgement, not legal standards," he said.

Judge Nicholas Wilson questioned Eadie on the lack of a witness statement from the prime minister.

"Isn't it odd that nobody has signed a witness statement to say 'this is true, these are the true reasons for what was done'?" he asked.

Eadie said cabinet documents had been produced which showed the aim of prorogation was to bring forward a new legislative agenda.

But O'Neill said the few documents offered could not be taken as the "whole truth", adding: "We cannot have a situation... where prorogation can be used with impunity to close down parliament whenever it becomes inconvenient."

A maximum 11 of the 12 Supreme Court judges are hearing the case.

They have not said when they intend to make a ruling following Thursday's closing hearings, during whihch lawyers for the Scottish government and for 1990s prime minister John Major are due to intervene. (AFP)
