There are four types of committees in the Knesset. Permanent committees amend proposed legislation dealing with their area of expertise, and may initiate legislation. However, such legislation may only deal with Basic Laws and laws dealing with the Knesset, elections to the Knesset, Knesset members, or the State Comptroller. Special committees function in a similar manner to permanent committees, but are appointed to deal with particular manners at hand, and can be dissolved or turned into permanent committees. Parliamentary inquiry committees are appointed by the plenum to deal with issues viewed as having special national importance. In addition, there are two types of committees that convene only when needed: the Interpretations Committee, made up of the Speaker and eight members chosen by the House Committee, deals with appeals against the interpretation given by the Speaker during a sitting of the plenum to the Knesset rules of procedure or precedents, and Public Committees, established to deal with issues that are connected to the Knesset.
