IMHO their work should be re-validated, if it fails to meet the standard, and if even a minor portion of their work appears to show purposeful tampering or deceit, then all of their work should be black-listed as well as these scientists themselves. Politics and game-playing is only an ethical violation. Tampering with ANY data is a violation of the very nature of being a scientist, and any 'scientist' willing to violate the core principles of the art cannot and should not be recognized as a scientist in any way, shape or form and neither should anything they produced be recognized in anyway as being scientific without complete validation from an impartial independent party.
