The Islamabad High Court delivered a judgment on the right to protest ahead of PTI's announced demonstration on which date?

Explanation: The Islamabad High Court ruled on 18 September 2026 that infringement of fundamental rights amounts to a breach of the Constitution, delivering the judgment ahead of PTI's planned protest on 27 September 2026. The court observed that the question was not whether a political party is entitled to protest, since it plainly is, subject always to the Constitution and law. For CSS Constitutional Law and Current Affairs, this links directly to Articles 15, 16, 17 and 19 and to judicial review of executive restrictions on assembly.
