The founder of pro-Palestinian activist group has won the right to challenge the British government’s decision to ban the group under anti-terrorism laws.

After the group broke into a military airbase in June and damaged two planes, the United Kingdom’s government proscribed Palestine Action under the Terrorism Act 2000. Proscription makes it a crime to be a member of the group, an offence that carries a maximum sentence of 14 years in prison.

The co-founder of a U.K.-based Palestinian rights organization that's outlawed by the British government has won a legal bid to challenge the decision to label the group a terrorist organization.
