ok my 5 cents worth..............
as I said on another post rules is rules and no player is bigger than the game, it's governing body or it's match representatives (umpires etc) - even WG had to face that....
as I understand it the ICC has issued the statement stating that the current tolerances stand until further notice - therefore the comments made by the testers is henceforth irrelevant to the current laws of the game - the only thing that is relevant is does his doosra conform to the current laws - in this case the answer is no and it is therfore an illegal delivery - he stops using it until such time as the law may be changed, or he faces being banned - simple!
anything else is a red herring...........
so far as his being disadvantaged by the outlawing of the delivery - hogwash as he is an 'offie' not a 'leggie' - the delivery in question is not his standard delivery and has proven to be a regular wicket taking delivery in the Home series v England only so far as I'm aware - the Aussies had no problems playing against it recently.........
so far as the presence of Yardley or Broad goes - there is enough video evidence for each not to be required to be present during the tests....
Yardley would be the person who's input would be least required for any authenticity as Murali has been playing Test cricket for years...
a review of the video footage can establish the physical characteristics of his match deliveries such as run up & bowling speed - if he fails to match this during testing then he can be advised of this - I don't know the rules but IMO if the testing is declared invalid for such a reason then his action has not been cleared and as such the delivery remains suspect & should not be used until proven otherwise.....
Broad can identify the specific action 'called' by him from video - similarly the testing video can be compared to the archives to again confirm that it was the same action as tested.....
I have no objection to a player having support, but they should not be present during the testing - the only people who should be there are the player, the testers and the ICC to ensure impartiality & their rules are complied with etc..........
surely by this time the ICC must have a set of rules & regs for such testing & it should be made as clear & impartial as possible.........
