It should come as no surprise that Saeed Ajmal's serpentine action has been sent for review. Should. Up until recently, though, the ICC has appeared to have been running a protection racket for bowlers with dodgy actions lest they be forced into making an unaccforceable decision. Now, belatedly, it would appear the ICC is cracking down on chuckers.
What is just as interesting as the ICC's apparent clamp-down on chucking, is the ICC's concomitant opinion of the rubber stamps at UWA:
Primarily, the ICC is unhappy with the biomechanics lab at the University of Western Australia in Perth, where bowlers with suspect actions have usually been sent for testing and correction. The ICC is not convinced that the lab's testing procedures are rigorous enough, at least to the standards they want. They are unhappy that not enough of the bowlers reported and then tested in recent years have been found to possess suspect actions.
