The government’s proscription of Palestine Action as a terror organisation is lawful, the Court of Appeal has ruled.
In February, High Court judges had ruled that the controversial decision to ban the group under the Terrorism Act was unlawful.
This came after a legal challenge from Palestine Action co-founder Huda Ammori.
The ban remained in place to allow an appeal from the government.
At a hearing on Monday, five Court of Appeal judges overturned the High Court decision, the BBC reports.
Lady Chief Justice Baroness Carr said the group “overly promotes unlawful violence that amounts to terrorism,” and it was therefore not a “sustainable proposition” to portray it as a non-violent protest group.
As a proscribed organisation, it is a criminal offence to belong to or support Palestine Action. This can be punishable by up to 14 years in prison.
Hundreds of people were arrested throughout last year at protests against Palestine Action’s proscription.
