Back in 2006 he was on the DGCA Class 2 panel of doctors. He was later on removed from there with a red note on the list that he is banned from doing the medicals or something like that I don't remember it. DGCA had some reason to remove this Good Doctor from that list, possibly complaints from those who went something similar to what HiAltFlyer experienced. I myself consulted him for class 2 and i would not call him fraud without having any reason or confirmed information, but he was for sure very strict.
Edit: Just found out he is back on that list.
