But an article by Derek Pringle in The Daily Telegraph suggests that Murali is no different from the vast majority of his fellow players. The current law states that there should be no straightening or partial straightening of the bowling arm during delivery, and research conducted with precise instrumentation has revealed that even bowlers like Glenn McGrath and Shaun Pollock, considered examplars of the classical action, occasionally go over the prescribed tolerance limit, bending their arms by as much as 12 degrees.
The tolerance levels had been set at five degrees for spinners, seven-and-a-half for medium-pacers, and 10 for quick bowlers, a scenario that had invited much criticism from past greats like Ian Chappell. But the study conducted by three prominent biomechanics experts suggests that the human eye can only detect a kink in the action if the straightening is more than 15 degrees. Based on these findings, the ICC is likely to extend the tolerance limit to 15 degrees for all bowlers, regardless of whether they bowl at Shane Warne's pace or Shoaib Akhtar's. Match officials will still be expected to note down suspicious actions, and pass on the information to the ICC. But unlike before, remedial action will now be the sole preserve of a new body to the set up to help bowlers with the rehabiliation process.
