Each house elects a chairman to control the internal procedures of the house. The houses also form Parliamentary committees and commissions to deal with particular types of issues. Unlike committees and commissions in previous Russian and Soviet parliaments, those operating under the 1993 constitution have significant responsibilities in devising legislation and conducting oversight. They prepare and evaluate draft laws, report on draft laws to their houses, conduct hearings, and oversee implementation of the laws. As of early 1996, there were twenty-eight committees and several ad hoc commissions in the State Duma, and twelve committees and two commissions in the Federation Council. The Federation Council has established fewer committees because of the part-time status of its members, who also hold political office in the subnational jurisdictions. In 1996 most of the committees in both houses were retained in basic form from the previous parliament. According to internal procedure, no deputy may sit on more than one committee. By 1996 many State Duma committees had established subcommittees.
