· Protection is provided only during sessions. Since it does not cover judicial proceedings in general, it does not cover judicial proceedings instituted against MPs before their election. However, any Member arrested before the opening of a session shall be freed during the term of the session at the request of the House (Art. 50 of the Constitution).
· Parliamentary immunity (inviolability) can be lifted (Art. 33 of the Diet Law):
