There is a reference to this repealed Article in Second Schedule, Part III, subsection 4(3), hence reference to Article 19a is retained in the Federal Constitution. Art. 20 1. This Article was repealed by Act 14/1962, section 7, in force from 01-02-1964, and read as follows: “20. (1) Subject to Article 21, the Federal Government shall, upon application made by any person in accordance with Clause (2), grant a certificate of naturalization to that person if satisfied— (a) that he has served satisfactorily for a period of not less than three years in fulltime service, or for a period of not less than four years in part-time service, in such of the armed forces of the Federation as may be prescribed by the Federal Government for the purposes of this Article; and (b) that he intends, if the certificate is granted, to reside permanently in the States of Malaya. (2) An application under this Article may be made either while the applicant is serving in such service as aforesaid or within the period of five years, or such longer period as the Federal Government may in any particular case, allow, after his discharge. (3) References in this Article to service in the armed forces of the Federation include references to service before Merdeka Day; and in calculating for the purposes of this Article the period of full-time service in such forces of a person who has served both in full-time and in part-time service therein, any two months of part-time service shall be treated as one month of full-time service.”. 2. The words “States of Malaya” which appear at the end of Clause (1)(b) were inserted by Act 26/1963, subsection 29(3), in force from 16-09-1963, in substitution for “Federation”. 3.
