It's a dangerous precedent. Is it only relevant because the decision was wrong at the completion of the game? What if they'd had an extra play at the end of the first half and scored?
A while back, North Sydney lost 22-2 to Sydney City. At one point, however, a Jason Taylor penalty goal was incorrectly put down as a miss and later shown to have been successful.
At the time it was missed, it would have given Norths a 4-0 lead. The entire complexion of the game could have been changed. Should they have been given the points given they found out after the fact that they were wrong?
Or do we only care about this when it's a team losing the game at the death?
