It added: "The umpires are still at liberty to report Waller in the future if they believe he is displaying a suspect action or that he is not reproducing the action that has been declared legal during this assessment. To assist the umpires in this respect, they have been provided with images and video footage of the bowler¿s legal bowling action."

The 30-year-old was initially reported after the second Test against Bangladesh in Khulna in November 2014 and, following an independent assessment carried out in December, was found to bowl with an illegal action in respect of his off-spin deliveries.
