The first source is Code section 401(a)(5)(G), which reads as follows:
QUOTE
(G) State and local governmental plans.--Paragraphs (3) and (4) shall not apply to a governmental plan (within the meaning of section 414(d)) maintained by a State or local government or political subdivision thereof (or agency or instrumentality thereof).
Code section 401(a)(3) and (4) are the paragraphs that impose the rules that prevent
benefits under most nongovernmental plans from discriminating in favor of highly compensated employees.
The second source is Code section 410©(1)(A), which reads as follows:
QUOTE
(1) The provisions of this section (other than paragraph (2) of this subsection) shall not apply to--(A) a governmental plan (within the meaning of section 414(d)), ....
Code section 410 is the section that imposes the rules that prevent
coverage under most nongovernmental plans from discriminating in favor of highly compensated employees.
The third source is Code section 401(a)(26)(H), which reads as follows:
QUOTE
(H) Exception for state and local governmental plans.--This paragraph shall not apply to a governmental plan (within the meaning of section 414(d)) maintained by a State or local government or political subdivision thereof (or agency or instrumentality thereof).
Code section 401(a)(26) is the paragraph that imposes the rules that prevent most nongovernmental defined benefit plans from covering less than (i) 50 employees of the employer, or (ii) the greater of--(I) 40 percent of all employees of the employer, or (II) 2 employees (or if there is only 1 employee, such employee).
Together, these three sources permit a state or local government plan to cover only one employee, even if that employee is a highly compensated employee, without providing comparable benefits to other employees under any other plan, so long as this is permissible under applicable state and local law.
