Juvenile? maybe but perhaps life's experiences have yet to make you think otherwise.
Using a local example (just for illustration purposes) let's say you are a professional employed by the gov. and you have to take them to task on a false disciplinary procedure.
When all the normal channels have been explored, the final arbiter is our AG who is employed by your employer with whom you have fallen out. If you think his decision is sub optimal where do you then take your grievance? Yeah nowhere..... That "little restriction" will apply to the UK too after Hop Tu Naa....
A scenario that's never happened to you? Long may that continue but until then, less of the pejoratives if you don't mind.
