### Other Forms of Interference
The European Court of Human Rights (ECtHR) defines "interference" with the right to freedom of assembly as any action by public authorities that restricts or impedes the exercise of this right. This includes measures taken before, during, or after an assembly, such as bans, dispersals, arrests, and punitive measures. The Court often refers to its established case-law to assess the proportionality and necessity of such interferences (
