In the wake of French fullback Benjamin Fall being cleared to play this weekend, World Rugby is going to come under intense pressure to re-write its rules and accept there are grey areas in rugby.
Without making some kind of change to legislate for accidental collisions the game is going to be in trouble and good referees such as Angus Gardner are going to be ever fearful that their reward for applying the letter of the law will be to thrown under the bus by their employer.
That has, to some extent, been Gardner's fate. The Australian essentially did everything right on Saturday night in Wellington.
He reviewed the footage from multiple angles. He sought in-put from his assistants and most importantly from the TMO and then he applied the law as it stood.
But the judicial panel who reviewed Fall's case saw it differently. They determined that the fullback's collision with Barrett didn't merit a red card. They have said, matter of fact, it was the wrong decision.
