The last paragraph is actually and sadly true. Apart from verifying certificate are authentic there's nothing upsc can do. These certificate are authentic on the government records but are obtained by using/furnishing false information. To cross check this information is difficult task for even DoPT take for example candidate belonging to business family can easily get NCL certificate by showing lower income which in reality is not but to verify the income and assets of each and every OBC NCL/EWS candidate is in itself very difficult task. At the max someone's disability can be verified by independent medical board.
