The British government acted lawfully when it banned the protest group Palestine Action as a terrorist organization, the Court of Appeal in London ruled on Monday.

Chief Justice Sue Carr said the group was not a civil disobedience organization as it claimed and that it operated with covert cells to destroy property at defense companies and on military bases.

“In our judgment, that premise was seriously flawed. It was not a sustainable proposition to portray Palestine Action as a non-violent organization,” Carr said.

The ruling overturned a decision in February by three senior High Court judges who found that despite the group promoting its political cause through some crimes, the scale of activities did not warrant a ban.
