Skeptics have raised doubts over tests carried out in a controlled environment. A bowler could easily change his action during a match to give it that extra tweak, especially while bowling the Doosra. However, the ICC is very close in clearing the cloud over that too. And Ajmal's tests have found "all his deliveries to be illegal."
In tests conducted on Ajmal in 2009, results showed that his arm was bent at 24 degrees when he brought it around his shoulder, but most importantly, he only straightened it by eight degrees before delivering the ball. Recent reports say it was Ajmal's off break that raised a few eyebrows. Earlier test results showed that oddly enough his arm flexed more while delivering his off break and arm ball than it did when he was bowling the doosra.
