UK planning law is not the same as medical research regulations.
UK planning law is the physical manifestation of legal tech debt. It will not be tackled until the daily mail and their readers are dead, and not replaced.
To make changes it requires lots of will from the government, and the consent of a bunch of people who are unlikely to give it.
medical regulation is fucking trivial by comparison. Most of it is arms length and technical. it can be changed according to evidence, rather than gut feeling. Its only in a few cases are there actual legal hard lines (like embryo research, and vivisection)
