"Entirely inconvenient ?" That's just the way the lawyers talk in court. Can't be seen to be dissing your colleagues.
The judges are sceptical of the Govt's position. At one stage, the judges asked why no-one swore the Cabinet minutes setting out the prorogue reasons was a true statement.
But, having said that, I think the Govt might win it. Their lawyer said Govt is allowed to prorogue and that the other side agrees with that. He said they're arguing over the length of suspension. And he argued the courts can't rule on that since it's like asking how long is a piece of string.
The court might allow Govt to get away with it but suggest that the law is changed in future to define how long prorogation can be?
