Chapter 6 deals with the various forms for assessing the constitutionality of the actions and decisions of governments, parliaments, and other authorities, collectively referred to as constitutional review. It highlights that constitutions often put in place provisions to this end on whom should be entrusted with the responsibility of interpreting and enforcing the constitution, and how this responsibility should be allocated. The chapter provides an overview of the different forms and models of constitutional review, and offers several considerations for striking the right balance among different values, including the protection of democracy, upholding the rule of law and the superiority of the constitution, but also the insulation of the courts from political influences, the protection of minorities’ representation and individual human rights.
