From a Guardian live news feed:

Scottish judges to continue case into legality of Johnson's letters to Brussels

Guardian Scotland editor Severin Carrellis in court in Edinburgh where Lord Carloway has rejected a call by the UK government to halt proceedings because the prime minister has met his legal requirements under the Benn Act.

The judge said he would continue with the case until it was clear that Downing Street has complied with the act in full – ie. to seek and, if offered, accept a Brexit extension from the EU. A date for the next hearing is yet to be fixed.

As I anticipated in earlier posts, the Government lawyers claimed that sending the letter discharged all its legal obligations under the Act. It is clear the court does not agree.
