No idea as to the accuracy of this statement, but it was stated that further testing protocols are necessary, and upholding the suspensions on shaky grounds would give solid grounds for legal action. Currently, the delay is because UMP will be chastised on penalties regarding recent (think Milliken) tire infractions, and they don't have a clear path in which to proceed that doesn't involve having all faith lost in their process. This could all be BS, just stating what I heard.
