Chapter 32 of the General Laws, as appearing in the 2012 Official Edition is hereby amended as that portion that requires an individual re-entering public service regardless of how much they pay to buy back into the system must work two years to be reinstated and fully vested for retirement  eligibility, by inserting an exemption from the requirement of the additional two year work period for someone who has attained the age threshold (age 60) and fully buys back into the system for all years necessary to fill the gap in years of service between their last public service employment and the current public service employment, allowing the person to be fully vested and eligible for retirement upon making said full payment into the retirement system under their current public service employment; thereby allowing those people that have successfully bought back 100% of their credible time and who were vested in the Public Retirement System to retain their eligibility, absent of the two year service period.
