Modifies provisions relating to the retirement of certain judges

This bill modifies retirement provisions for judges in Missouri, establishing new eligibility requirements and contribution rules for those who first became judges on or after January 1, 2011. Under the new rules, judges aged 67 with at least 12 years of service or those aged 62 with at least 20 years of service may retire with benefits, while those with shorter service periods can retire at age 67 or 62 with reduced compensation proportional to their years of service. The legislation requires judges to contribute four percent of their compensation to a retirement account, with the state employer paying these contributions on their behalf and crediting interest annually based on Treasury rates. Judges who terminate employment may request a refund of their contributions and interest, though this forfeits future retirement benefits unless they return to the system and repay the amount with interest.
