807 CMR, § 17.03
Members will be notified when the System believes he or she has a claim for workers' compensation benefits that has not been initiated or prosecuted fully. The member will be given a reasonable opportunity to initiate or prosecute such claim. If the member fails or refuses to initiate or prosecute such claim within a reasonable period of time, the System will initiate or prosecute the claim on behalf of the member to the extent allowed by law. The member will cooperate in the System's initiation or prosecution of such claim, as required by M.G.L. c. 32, § 14(2). The member's failure to cooperate in the System's pursuit of such claim may, after notice and an opportunity to be heard, result in the suspension of the member's benefit for so long as the member fails to cooperate.
