Michigan Compiled Laws, Chapter 38. Civil Service and Retirement § 38.2511

Sec. 511. (1) Except as provided in subsection (2), the retirement allowance payable to a retirant whose effective date of retirement was before January 1, 1980 or to an option A beneficiary of a deceased retirant whose effective date of retirement was before January 1, 1980, as supplemented by section 510  1 if applicable, shall not be less than $10,000.00 per annum if the retirant had at least 8 years of service credited under the former judges retirement system or the former probate judges retirement system. Except as provided in subsection (2), the retirement allowance payable to a beneficiary, other than an option A beneficiary, of a deceased retirant whose effective date of retirement was before January 1, 1980, as supplemented by section 510 if applicable, shall not be less than $8,500.00 per annum if the retirant had at least 8 years of service credited under the former judges retirement system or the former probate judges retirement system. The payment of an increased retirement allowance under this section is effective on October 1, 1996 and is not payable for any month beginning before October 1, 1996. However, for a retirant or beneficiary of a deceased retirant who is eligible to receive an increased retirement allowance under this section, who is receiving a retirement allowance pursuant to service credited under the former judges retirement system, and who is receiving a retirement allowance pursuant to service credited under the former probate judges retirement system, the retirement system, pursuant to this section, shall only increase the retirement allowance that is the largest in amount. If, for a retirant or option A beneficiary, that retirement allowance is $10,000.00 or more; or if, for a beneficiary other than an option A beneficiary, that retirement allowance is $8,500.00 or more, the retirant or beneficiary is not entitled to receive an increased retirement allowance under this section.

(2) For a retirant or beneficiary of a deceased retirant who is eligible to receive an increased retirement allowance under subsection (1) and who is receiving an annuity or retirement allowance from another publicly supported retirement system attributable to the same years of service, other than federal social security benefits, the retirement allowance payable to that retirant or beneficiary shall be the amount specified in subsection (1) minus the amount of the annuity or retirement allowance payable from the other publicly supported retirement system, but not less than the retirement allowance as supplemented by section 510, if applicable, or not less than the annuity payable under this act on September 30, 1996.

(3) This section does not apply to a retirant or beneficiary of a deceased retirant who received an increased annuity under section 16b of the former probate judges retirement system.  2
