I think Hair, whatever his virtues as a decision-making umpire, is a grandstanding buffoon. No one man is bigger than a sport &, as he has very clearly lost the faith of a signifcant proportion of the cricketing fraternity of nations, he has no future in the international game. His initial decision to dock Pakistan 5 runs for the "ball tampering" was a terrible one and isn't mitigated by the fact that Inzi's (well, I say Inzi but I have serious doubts that he was the main instigator, but that's beside the point) decision to refuse to come out after tea was worse. I actually believe that the decision to award the game by forfeit was the correct one as a team cannot be seen in to be acting in open defiance of the standing umpires & the playing conditions for their own ends (whatever they may have been).
Hair has been slightly hung out to dry over this issue though because (whatever one thinks of him as an umpire or as a person) it's inescapable that he has been treated differently to Doctrove. Mali's contention that there is no reason why Hair can't umpire tests again is patently a nonsense (too many teams don't want him) but, for whatever reason, he cannot say this. The removal of Hair is already a step down the route of teams choosing their own umpires (or, more accurately, choosing the ones they don't want) but, if this is openly admitted, it shows the ICC to be lead by certain forces. Which means that Mr Mali is left defending the indefensible.
As I said earlier I suspect this will end with a significant pay-out to Hair, possibly by an out of court settlement to further save the ICC's blushes.
