Judiciary law & precedent, do both look like set questions, with the words “please discuss” often after them which you would be expected to be able to answer yourself.
If this is wrong please elucidate.
I think alos people havent tried to answer.
There are whole chapters on this in admin law or constitutional law text books
You have to decide which courts are courts of record and therefore can set precedent - The GMC for example is a court but is not bound by its own previous cases but IS bound by high court cases affecting it
Then you have hierarchy of courts that can modify lower courts
You should mention Denning in the COurt of Appeal tried to over rule a House of Lords case
and that finally the House of Lords oops showing my age - Supreme Court can over rule itself but does so rarely
