Head of Counter Terrorism Policing Laurence Taylor said:
“Policing’s role is to enforce the law, and to do so without fear or favour, as the public would expect.
“Proscription is, and always has been, a matter for the government.
“Following today’s judgment, the Home Secretary has stated she intends to lodge an appeal.
“The court has ordered that the proscription order remains in force until further order of the court.
“We recognise this is an unusual set of circumstances, and until further order by the court, Counter Terrorism Policing will approach enforcement pragmatically and proportionately, and will continue to work with forces across the country.”
