The Court of Appeal held that the determining date is the date of the representations for reinstatement. The relevant portion of the judgment is reproduced as follows: [22] In essence, s.35 of Act A1615 states that where any representation for reinstatement is made under s.20 of the Act before the coming into force of the amended Act, it shall proceed under the unamended Act. [23] If the representation for reinstatement was made before 1.1.2021 and the Minister refers it before 1.1.2021, there is no ambiguity. Likewise, if the representation and referral were made after 1.1.2021. ... [25] The determining factor is when the said representation for reinstatement was made to the Department of Industrial Relations under s.20 of the Act. … [31] Instead, we emphasize again that the critical issue is the timing of the representation for reinstatement under s.20(1). If the said representation was made before the coming into force of the amended Act, the proceedings should be based on the unamended Act. ... [35] Therefore, by applying judicial precedent and the provisions of s.35 of Act A1615, any challenge against an award of an Industrial Court must be by way of a Judicial Review. … [37] Given this finding, we do not find it necessary to consider the substantive appeal.”
