In the absence of express transitional provisions, legislative amendments that affect the jurisdiction of a court do not apply to proceedings that were already pending before that court at the time the amendment came into effect. An application is 'pending' when it has been delivered (served and filed) in the court. The presumption against retrospectivity, grounded in the rule of law and principles of fairness and legal certainty, means that parties who have already initiated proceedings in a particular forum retain the right to have those proceedings determined by that forum, notwithstanding subsequent amendments that would otherwise divest the court of jurisdiction. However, this protection extends only to pending proceedings, not to potential proceedings based on compliance orders or written undertakings that had not yet been brought before the court at the time of the amendment.
