Sharia has been previously declared the chief source of all legislation in Sudan's 1968, 1973 and 1998 Constitutions.[77] In 2005, Sudan adopted an interim national constitution; it removed some references to Sharia, but included Sharia-derived criminal, civil and personal legal codes, as well as Sharia-mandated hudud punishments.[78] The Criminal Act of 1991 prescribes punishments which include forty lashes for drinking alcohol, amputation of the right hand for theft of a certain value and stoning for adultery.[79][80] However, there is no record of either any amputation or stoning ever having taken place in Sudan.[81]
