After the military coup in 1980 led by Dési Bouterse, Bruma became the formateur of the Chin A Sen government, in which, in addition to civilians, members of the National Military Council (NMR) were involved. Chin A Sen, a physician, was a member of the PNR, but was not politically active before. Afterwards, he was mainly active as a lawyer, and sometimes he gave political advice. In October 2000, he was robbed at his home, resulting in a skull fracture. A few weeks later, he died of those injuries in a hospital at the age of 75. President Ronald Venetiaan gave a speech at his state funeral.
