Nearly ever year. At least I know of it since 2009. The government has not done the grading in PSUs and after getting the NCL certificate from HoD in PSU, govt has come up with its own findings and denied NCL benefits.
However, in that case you are treated as a general candidate , and not debarred from misrepresentation of facts or anything.
