Appeals redirected from tribunals to courts, allowing appeals to the principal civil court from specified highway administration orders. The Act revises definitions and procedure by defining Court as the principal civil court of original jurisdiction (including the High Court in ordinary original civil jurisdiction), omitting multiple tribunal-related provisions, substituting references to Tribunal with Court, and replacing section 14 with an appeals provision that directs appeals from specified Highway Administration orders or actions (excluding issuance or service of notices) to the Court.
