The UK government closed the final day of the judicial review into Palestine Action by presenting secret evidence, hidden from both the group’s lawyers and the public, to justify its ban on the direct-action organisation.

Following brief open-court submissions from government lawyers on Tuesday, the court asked lawyers representing Palestine Action co-founder Huda Ammori, as well as members of the public and journalists, to leave.

A portion of Tuesday’s hearing was held in closed session to allow the government to present material it says cannot be disclosed on national security grounds. It means that if Ammori loses her case based on the secret evidence, neither she nor her team will know what the government argued against her or Palestine Action.
