The document discusses a medico-legal expert's opinion on the cause of death of Prabhudas Madhavaji, aged 40. After reviewing autopsy reports and test results, the expert concludes that the cause of death was acute renal failure resulting from rhabdomyolysis. Rhabdomyolysis is the breakdown of muscle fibers which releases myoglobin into the bloodstream, overloading and damaging the kidneys and potentially causing renal failure. While no injuries were found on the body, the autopsy and histopathology reports found evidence of muscle breakdown and kidney damage consistent with rhabdomyolysis.
