This document, which was prepared at the request of the Chairman of the House Committee as background information for parliamentary deliberations on the issue, presents the practices regarding parliamentary inviolability in several states in the world. In addition, the document presents a set of considerations that the legislature should take into account when it formulates legislation on this issue. The document is divided into three parts: The first part presents a comparative charting of the intensity of immunity in Israel, and in a selection of states in the world. In the second part, alternatives for legislative considerations on the issue are presented, alongside references to countries in which such alternatives exist. In the third part, parliamentary inviolability arrangements in France, Spain, Italy, Germany, United Kingdom, the United States, the Netherlands, Canada and Turkey, are presented. These states represent both Continental law and Anglo-American law. A summarizing comparative table, prepared by the jurist Dr. Suzie Navot for the Report of the Public Committee for the Reexamination of the Issue of Parliamentary Immunity of Knesset Members, 1997, is attached at the end.
