ANNOTATIONS

Repeals and reenactments. — Laws 1987, Chapter 253 repealed former 10-11-4 NMSA 1978, as amended by Laws 1985, ch. 253, § 1, relating to retirement association and retirement board, and enacted a new section, effective July 1, 1987.

The 2026 amendment, effective May 20, 2026, allowed the public employees retirement board to set the rules administratively for how withdrawn service credit is paid for, restored, or refunded to members; in Subsection D, deleted "Full" preceding "Payment", and after "shall be made in" deleted "a single lump-sum amount in"; and in Subsection F, after "Withdrawn member contributions" deleted "may" and added "shall", after "repaid in" deleted "increments of one year in", and after "established by the retirement board" deleted "Full payment of each one-year increment shall be made in a single lump-sum amount in accordance with procedures established by the retirement board.".

Severability. — Laws 2013, ch. 225, § 93 provided that if any part or application of Laws 2013, ch. 225 is held invalid, the remainder or its application to other situations or persons shall not be affected.

The 1997 amendment, effective June 20, 1997, added the third sentence in Subsection A and inserted "retirement" preceding "board" throughout the section.

Early retiree purchase of service credits. — Despite the clarity and precision of its formula for computing the cost of a retiring employee's additional purchased service credit, § 139 of Laws 1987, ch. 253 (uncompiled) was ambiguous; it was ambiguous because of its reference to the seventy-fifth fiscal year (the 12-month period ending June 30, 1987), which had already ended when § 139 became effective on July 1, 1987. The section provided that an employee could purchase up to five years of credited service "during the seventy-fifth or seventy-sixth fiscal year," subject to various conditions. Not only was the statute ambiguous by referring to both the seventy-fifth and seventy-sixth fiscal years at the same time, it was also internally inconsistent; the cost for an additional year of service credit had already been fixed by Section 3 of the 1986 amendment to this article (Chapter 89), and no one argues that § 139 was intended to change that cost, retroactively, to comport with the formula spelled out later in § 139. Thus, the early retirees in the seventy-sixth fiscal year under Laws 1987, Ch. 253, § 139 were required to pay an equivalent amount to purchase service credits as paid by early retirees under Laws 1986, ch. 89, § 3.
