Effective immediately, in the processing of a disability retirement or death benefit presumption requiring successful passage of a pre-employment physical, when it is determined that the records of such physical no longer exist through no fault of the member, the Retirement System shall accept, in lieu of such records, a sworn statement from an authorized representative of the employer indicating, to the extent known, the reason the records no longer exist, that such member would have been required to undergo a physical examination at or shortly after hire, and that the member would not have been so hired without successfully passing the examination.
