Contingency-Conflict with federal law- 2018 c 257 : "The department of retirement systems shall make reasonable efforts to seek guidance, if available, from the federal internal revenue service to ensure this act does not jeopardize qualification of the state retirement plans under section 401(a) of the internal revenue code. If the federal internal revenue service issues guidance stating that this act is in conflict with the plan qualification requirements for governmental plans in section 401(a) of the internal revenue code, and the conflict cannot be resolved through administrative action or statutory change, then this act is null and void."
