Explain the jurisdiction of the Special Court and of quasi-judicial bodies, showing how the ordinary courts supervise the periphery.

Jurisdiction = the court's power to hear, decide and execute a class of cases — the lawful authority's boundary. Sources: the Constitution (the court structure's spine — Part 11, Arts 126–156) and statute (the Civil Procedure Code 2074, the Criminal Procedure Code 2074, the special statutes' tribunal clauses). The kinds (the exam map): Territorial (place) · pecuniary (amount) · subject-matter (the case's kind); Original vs appellate; exclusive vs concurrent; civil vs criminal; ordinary vs extraordinary (the writs). Nature's rules: Jurisdiction is conferred by law, not consent — parties cannot by agreement give a court power it lacks; A decision by a court without jurisdiction is a nullity (void, coram non judice — however excellent its reasoning); Jurisdiction is determined at inception (later facts don't oust it); objections to it may be raised at any stage. The distinction that saves confusion: jurisdiction is the power question, merits the rights question, procedure the route question — this course is the third, built on the first.
