1. The facts:
On 28.4.2012, the Complainant Nirmala's husband K. T. Prasad about 39 years (since deceased, for short the ˜patient'), for his upper abdominal pain, was admitted in M/s Apollo Hospital Enterprises Ltd. at Chennai (for short, ˜OP - 1 / Apollo Hospital'). The Gastroenterologist, Dr. Ubal Dhus, (OP - 2) examined the patient, CT scan abdomen and the routine investigations were done. The Radiologist, OP - 3 reported CT scan as pancreas appears swollen with suboptimal parenchymal enhancement particularly in the body and the tail and small area of necrosis infection at neck of pancreas etc. CT findings were suggestive of acute pancreatitis with diffuse fatty infiltration of liver. It was alleged that the radiologic findings of necrosis (dead cells) was ignored by the OP - 2, thus he failed to detect suspected cancer. The patient remained in the hospital for six days and discharged on 3.5.2012 with an advice to come after six weeks. On 16.6.2012, the patient was examined by the OP - 2 and diagnosed as Erosive Gastritis. Again on 21.1.2013 the patient was admitted to Apollo Hospital with the complaints of severe upper abdominal pain. The CT scan of abdomen was done on 22.1.201
