Judicial reviews have always been available, based on the ability to make x decision based on y evidence. As opposed to not liking the decision.

I chaired a health authority that was taken to judicial review over the granting of a GP contract and that was some experience......

My time as a regulator suggests if such a proposal goes through, enforcing regulations in any arena would be difficult. In my old line of work, it would mean a large pharmaceutical company could fetter every decision under a regulatory umbrella whilst a poor independent pharmacy / chemist shop would have to take it on the chin via the appeals process.
