A member of this plan whose membership continues under Section 2.124.850 of this chapter and who becomes disabled by reason of a bodily injury or physical or mental illness may retire for disability. If such member is qualified for voluntary service retirement, he or she shall receive an allowance of an amount equal to the deferred service retirement he or she would have received if he or she had elected to retire from service on the date when the retirement system manager authorizes his or her retirement for disability. If such member is not qualified for voluntary service retirement, he or she shall receive a disability retirement allowance of one and one-half percent of final compensation for each year of service, but in no event shall such allowance exceed the service retirement allowance to which such member would be entitled upon attainment by him or her of age fifty (50). (Prior code § 34.05.536)
