The Fall and Rise of the Islamic State (2008) explains the increasingly loud call for implementing shari'a in Muslim countries. Feldman argues that current systems of government in certain Muslim countries have unchecked executive power because the previous system – in which scholarly interpretation of shari'a served to counterbalance executive power – was undermined by failed reforms in the modern era.[45] Drawing on the success of this previous system, Feldman proposes a viable path for Islamic governance that depends on legislators to serve as the check on authoritarian executives.
