(2) Where any matter is pending before a tribunal having jurisdiction therein, or believing in good faith that it has such jurisdiction, the parties thereto, their pleaders, mukhtars, revenue-agents and recognized agents, and their witnesses acting in obedience to a summons, shall be exempt from arrest under civil process other than process issued by such tribunal for contempt of Court while going to or attending such tribunal for the purpose of such matter, and while returning from such tribunal.
