Section 30 of the Protection of Human Rights Act, 1993 shall not apply where:

The proviso to section 30 says the section does not apply if "a Court of Session is already specified as a special court" or "a special court is already constituted" for such offences under any other law for the time being in force. Either kind of existing special court is enough. A special bench of the High Court or a direction of the State Government is not one of the exceptions.
