Taskin and left-arm spinner Arafat Sunny has been barred from bowling and will have to undergo action correction before they can comeback into competitive cricket.
According to a report in ESPNCricinfo, BCB president Nazmul Hasan Papon has communicated with ICC chairman Shashank Manohar and Chief Executive Dave Richardson intimating them that the board was not convinced about independant assessment of Taskin's bowling action.
"We are not convinced about Taskin as of now. We don't have any reason to be satisfied with the report," Nazmul was quoted as saying by the website.
Hassan said the BCB was trying to circumvent the normal procedure of appealing in a bid to quickly overturn the decision made on Taskin. The ICC had said on Saturday that "not all of Taskin's deliveries were legal".
"We are trying to do something outside the normal procedure where the player requests a reassessment, which we feel is a complex process. I don't think we can do anything more that what we have done. I believe that the ICC will observe our points and give a logical reply.
