Australian Darrell Hair, the umpire at the centre of the forfeited Oval Test, maintains he was correct to penalise Pakistan and award the game to England.
And he dismissed criticism of his past performance officiating Asian teams.
"People who know me know I would not take action unless I really thought it was necessary," he said.
"I have umpired quite a lot in the sub-continent and when the ICC have asked me to do a job I try and do it to the best of my ability."
