Ashoka Desilva back in ICC elite panel despite failing umpiring test recently

[DomainK]

ICC has recalled Ashoka Desilva of Srilanka back to the elite panel. Interestingly Desilva failed in a written umpiring test in Srilanka. Does ICC regularly test umpires' knowledge of the rules? We don't have any dearth of examples where umpires seem not to know obvious rules of the game, which is very embarrassing. When the news of Desilva's failure came in, I thought Desilva's career with ICC was over. But surprisingly, he is back again.
