that there is no concrete evidence to prove that notice has been served on the petitioner. But, an affidavit is filed by the arbitrator, who passed the award in ARC No. 1656/2000, wherein he has stated that he caused service of notice on the respondent. But, at the same, time, he also admits that the records are not available to prove the same. I am at a loss to understand how a person who has passed an award years ago can, with any amount of certainty, remember whether notice in that ARC had been served on the respondent. That being so, I am not inclined to accept the averments in the affidavit of the arbitrator at its face value. It is admitted that there is nothing on record to show that notice has been served on the petitioner in the ARC. That being so, the award in the ARC and the execution proceedings pursuant thereto are liable to be quashed.
