 While the Assembly has made strong and often popular efforts to assert its authority and independence against the executive, it is still viewed generally in a negative light by the media and many of the Nigerian people.The Assembly sits for a period of at most four years, after which time the President is required to dissolve it and call a new Assembly into session.The Senate has the unique power to impeach judges and other high officials of the executive including the Federal Auditor-General and the members of the electoral and revenue commissions.
