"…If the judicial review were to fail then the liability to penalties would not be removed but there would be a statutory right of appeal to the First-tier Tribunal if HMRC were not satisfied that the existence of the judicial review proceedings was a reasonable excuse for not paying 50 18 the penalties. The taxpayers would have the opportunity first of all to make representations to HMRC and, if those fail, to appeal to the First-tier Tribunal in order to persuade the First-tier Tribunal that they had a reasonable excuse for not paying the penalties. It seems to me that whether or not the claimants accede to the PPN and pay the sum which 5 is said to be due, pending the outcome of the judicial review, or do not pay it, in neither case is the judicial review rendered nugatory."
