From NRA-ILA:

Exactly two weeks after the Czech Republic announced that they would challenge restrictive changes to the European Union’s European Firearms Directive in the European Court of Justice, the small nation has once again acted to defend themselves against transnational gun controllers. On June 28, the Czech Chamber of Deputies (the lower house of the Czech Parliament) approved a constitutional amendment to protect Czech citizens’ right to possess firearms and ammunition, with a reported 139 of 200 deputies voting in favor.

Specifically, the proposed constitutional amendment ensures that Czech citizens have a right to keep and bear arms in order to participate in preserving national security.
