(ii) that the decision of Wong Pot Heng's case is still binding and the amendment to Section 20 of Act 388 has not changed the situation. In order to give the Exemption Order its retrospective effect, the Act must make provisions for it. [59] Such findings by the Court of Appeal in Syed Ibrahim is erroneous as it had completely disregarded the effect of the amendments made to the long title, section 20 of the Interpretation Acts 1948 and 1967 [Act 388] and the insertion of new Section 17A vide Act A996. Section 20 of Act 388, after its amendment, has dispensed with the need for an express power to be given by the Parent Act and that the delegated authority is entitled to legislate retrospectively notwithstanding the absence of any express provision in its Parent Act. [60] Therefore, it follows that the decision in Wong Pot Heng which enunciated that 'a subsidiary legislation could only be made with retrospective operation if it was authorised by an express power in, or by necessary implication from its Parent Act is no longer binding, in view of the subsequent amendments made to the long title, Section 20 of the Interpretation Acts 1948 and 1967 [Act 388] and insertion of new Section 17A vide Act A996. [61] The Court of Appeal decision in Syed Ibrahim's case on this point was made per incuriam as it completely disregarded the law prevailing at the time. [62] We therefore answered Question 3 in the negative, while we answered Questions 4 and 5 in the affirmative. Questions 7 and 8 [63] At the time when the Members of Parliament (Remuneration) (Amendment of First Schedule) Order 2015 was made on 16.2.2015, the Respondents' entitlement to pension under the former (old) paragraph 20 of the First Schedule to the Members of Parliament (Remuneration) Act 1980 [Act 237] which stated that 'Whenever the salaries of a Member are revised, the salary on which a pension granted under paragraph 2 or a derivative pension granted under paragraph 5, 6 or 7 is based shall be adjusted to the revised salary as appropriate and the pension or derivative pension recomputed accordingly' is not an accrued or acquired right which is saved or protected by Section 30(1)(b) of the Interpretation Acts 1948 and 1967 [Act 388]. [64] The Respondents' entitlement to pension under the former (old) paragraph 20 of the First Schedule to the Members of Parliament (Remuneration) Act 1980 [Act 237] is a contingent right which is neither saved nor protected by Section 30(1)(b) of Act 388. [65] The unaccrued inchoate right to receive an increased pension which was not saved by Section 30(1)(b) of Act 388 can be modified or extinguished by retrospective amendment. [66] We answered Questions 7 and 8 in the affirmative. Other issues [67] On the alleged unconstitutionality aspect of the new subparagraphs 20(1) and 20(2) of the First Schedule to the Members of Parliament (Remuneration) Act 1980 [Act 237] as we have articulated above, the provisions are not unconstitutional as they have not infringed the Respondents' alleged constitutional rights under Articles 132, 147 and 160(2) of the FC. [68] The Court of Appeal, in its analysis, held that the Respondents were not members of the public service and hence, the protection accorded under Article 147(1) of the FC did not apply. [69] Articles 132 and 147 of the FC do not apply to the Respondents. We wish to reiterate that those Articles are specifically to cater for the members of the public services and the protection of pension rights of members of the public services. [70] Pursuant to clear provision of Article 132(3) of the FC, the public service shall not be taken to comprise the office of Member of either House of Parliament. The protection of pension rights under Article 147 of the FC only applies to members of the public services listed under Article 132 of the FC and does not apply to the Respondents who were not members of the public services. [71] The provisions of Articles 132(1), (3) and 147(1) of the FC are very clear without any ambiguity. Thus, the Court must give effect to those provisions without attempting to modify and qualify them, particularly where there is no ambiguity. [72] All the Respondents started serving as members of Parliament after the date of repeal of Act 394 i.e. 20.11.1992. The Parliamentary Service Act 1963 [Act 394] had been repealed by paragraph 7(d) of the Constitution (Amendment) Act 1992 [Act A837], which came into operation on 20.11.1992. [73] Consequently, effective 20.11.1992, the category of public service mentioned in Section 2 of the Pensions Adjustment Act 1980 [Act 238] shall no longer include the Parliamentary Service referred to in the Parliamentary Service Act 1963 [Act 394]. [74] The express provisions of Article 132(3) read together with Article 132(1) of the FC clearly exclude the office of Member of either House of Parliament from the list / category of public services. There is therefore no ambiguity as far as the provisions of Articles 132(1), (3) and 147(1) of the FC are concerned. It is the Court's duty to give effect to those provisions without attempting to modify and qualify them, particularly where there is no ambiguity. [75] Therefore, there will be no issue that the amendment to paragraph 20 of the First Schedule of Act 237 had resulted in a "less favourable situation" to the Respondents as allegedly guaranteed by Article 147(1) of the FC. [76] The Respondents referred to the case of Aminah Ahmad in support of their case. However, Aminah Ahmad's case is peculiar to its own facts, poles apart from our present appeal as we have explained above. The challenges therein were to the validity of certain amendments to the Pensions Adjustment Act 1980 [Act 238] on the ground that they are ultra vires Article 147 of the FC. Act 238 and Article 147 of the FC apply to the officers/member of the public services and not those who are not members of such public services. Both Act 238 and Article 147 of the FC are not applicable to the Respondents, hence Aminah Ahmad's case is distinguishable and cannot be applied this appeal. [77] In the present appeal, premised on Article 132(3) of the FC, the Respondents, being previous Members of either House of Parliament, shall not be considered as members of the public services (unlike the situation in Aminah Ahmad's case). [78] A situation of "not less favourable" or "not less favourable test" as clearly embodied in Article 147(1) of the FC is specifically referred to the award of pension granted to a member of any of the public service and not to the Respondents (former Members of either House of Parliament) who were not considered as members of the public services listed under Articles 132(1) and (3) of the FC. [79] Therefore, there will be no issue that the amendment to paragraph 20 of the First Schedule of Act 237 had resulted in a "less favourable situation" to the Respondents as allegedly guaranteed by Article 147(1) of the FC. [80] The constitutionality of the FC is considered from the perspective of the Constitution itself, and it is not to be interpreted by reference to other statutes. The Pensions Adjustment Act 1980 [Act 238] or the Parliamentary Service Act 1963 [Act 394], each being a subsidiary legislation qua the FC, could not be interpreted in such a way as to fill any lacuna (if at all there is) the FC. [81] Neither could Act 238 or Act 394 competent legal instruments to confer the status of members of the public services to Members of Parliament (Respondents) under Articles 132 and 147 of the FC. Conclusion [82] We answer the questions posed to us as follows: Question 1 In view of the subsequent amendments made to the long title, Section 20 of the Interpretation Acts 1948 and 1967 [Act 388] and insertion of new Section 17A vide Act A996, whether Section 20 of the Interpretation Acts 1948 and 1967 [Act 388] after its amendment has dispensed with the need for an express power to be given by the Parent Act and that the delegated authority is entitled to legislate retrospectively notwithstanding the absence of any express provision in its Parent Act? Affirmative Question 2 Whether the decision in Kerajaan Malaysia v. Wong Pot Heng & Anor [1997] 1 MLJ 437 which enunciated that 'a subsidiary legislation could only be made with retrospective operation if it was authorised by an express power in, or by necessary implication from its Parent Act' is no longer binding in view of the subsequent amendments made to the long title, Section 20 of the Interpretation Acts 1948 and 1967 [Act 388] and insertion of new Section 17A vide Act A996? Affirmative Question 3 Whether the previous Members of Parliament's entitlement to pension under the former (old) paragraph 20 of the First Schedule to the Members of Parliament (Remuneration) Act 1980 [Act 237] which stated that 'Whenever the salaries of a Member are revised, the salary on which a pension granted under paragraph 2 or a derivative pension granted under paragraph 5, 6 or 7 is based shall be adjusted to the revised salary as appropriate and the pension or derivative pension recomputed accordingly' is an accrued or acquired right which is saved or protected by Section 30(1)(b) of the Interpretation Acts 1948 and 1967 [Act 388], at the time when the Members of Parliament (Remuneration) (Amendment of First Schedule) Order 2015 was made on 16.02.2015 Negative Question 4 Whether such previous Members of Parliament's entitlement to pension under the former (old) paragraph 20 of the First Schedule to the Members of Parliament (Remuneration) Act 1980 [Act 237 is a contingent right and neither saved nor protected by Section 30(1)(b) of the Interpretation Acts 1948 And 1967 [Act 388]? Affirmative Question 5 Whether the unaccrued inchoate right to receive an increased pension which was not saved by Section 30(1)(b) of the Interpretation Acts 1948 And 1967 [Act 388] can be modified or extinguished by retrospective amendment? Affirmative Question 6 In view of amendment to long title of the Interpretation Acts 1948 and 1967 [Act 388] vide Act A996, whether the scope and character of Act 388 is not merely limited to meanings of words used in written law / interpreting words and phrases of the statutes? Affirmative [83] Given the aforesaid, we allowed the appeal with no order as to costs. We set aside the decision of the Court of Appeal and affirmed the decision of the High Court.
