This is a pretty good one. The status of a runner who has scored seems in question - but I dont know that that is the big the question. The big question is the score.

Rule 5.5.1 - A run scores when...

So are there any criteria which would negate that score?

There is no legit appeal being made, so there is no rule negating the run scoring .. ie the score is in the books. The runner could do any number of things, Interfere (were something else going on), get ejected, do a hand stand, beg the umpire not to score the score because they dont want to play extra innings and want to go home, purposely return to 3rd to prevent the score to prevent run rule.

But they cant.

It's in the book. The ruling on the field was essentially correct in my view, with the exception that I dont believe the status of the runner is the big question - the big question is can that runner do anything at that point to unring the scoring bell?

Barring an appeal sitiation, I dont believe they can.
