Constitutional law handbook

In public law, abrogation is the proposing away of a right, power or value, by a public body in delegating power or failing to carry out a responsibility or duty.
The abrogation of such a responsibility or duty, unless required by primary legislation would amount to an unconstitutional delegation of power to a foreign government or other sovereign power.

In law, South African constitutional litigation is the area dealing with the rules and principles concerning constitutional matters in the country of South Africa.
It includes the jurisdiction of the Constitutional Court of South Africa, the High Court of South Africa, the Supreme Court of Appeal of South Africa, and certain other specialist courts.
It also includes the consideration of rules peculiar to these courts that are relevant to constitutional litigation, such as the admission of an amicus curiae, the duty to raise a constitutional matter as early as possible in proceedings, and the duty to join the relevant organ of state in a case involving a constitutional issue.
