The Metropolitan Police will resume arresting protesters for displaying signs supporting Palestine Action.
This follows a pause last month after the High Court ruled the government’s ban on the group unlawful.
The Met announced Wednesday that arrests would recommence as the appeal against the ruling is expected to take months.
Deputy Assistant Commissioner James Harman said: “While the High Court has found the proscription of Palestine Action to be unlawful, it has confirmed the impact of that judgment will not take effect until the Government’s appeal has been considered which could take many months.
“That means it is still a criminal offence to support Palestine Action.
“We must enforce the law as it is at the time, not as it might be at a future date. We must do that consistently and without fear or favour.”

He went on: “The High Court decided on February 25 to grant the Home Secretary permission to appeal and to leave the proscription in place pending the outcome of that appeal.
“Having now considered our position in light of that decision, taking into account all the circumstances, we have determined that while Palestine Action remains proscribed and support for it remains unlawful under the Terrorism Act, we must continue to enforce the law and this is likely to involve the arrest of those committing offences.”
More than 2,700 people have been arrested so far for allegedly expressing support for Palestine Action since it was banned as a terrorist group last year.
Protesters have arranged mass rallies where demonstrators hold up signs saying “I oppose genocide, I support Palestine Action”.
The trials of hundreds of people accused of holding up the placards have been put on hold while the legal battle over whether the group should have been banned rumbles on.
Earlier this month Chief Magistrate Paul Goldspring said the cases would be delayed until after the High Court Appeal over the ban is heard.
Proscription makes it a criminal offence to belong to or support Palestine Action, punishable by up to 14 years in prison.
