It's established that arbiters have the power to declare a game lost and expel players from tournaments if they are detected consulting a chess engine whilst playing. This may also extend to retrospectively changing the results of earlier rounds and rating the games as lost. This naturally identifies the player provided the event is known and the cross-table published, but not in a way that jumps out with a casual Google search.
