I'm not a lawyer but I have a basic understanding. In the UK case law is probably more applicable to what we call civil law than criminal law. Most things are criminalised by legislation (like French law) these days but civil law matters like the definition of the tort of negligence, contract law etc are more dependent on precedent (common law). So an example which is the basic definition of the modern interpretation of negligence is the snail in the ginger beer case [0]. This is a classic case which lawyers and quite a few other professionals study. I was taught this at Architecture School and I still get updates on cases pertinent to construction through the CPD program of my professional association. Obviously you can disappear down the rabbit hole pretty quickly when trying to figure out how precedent might apply to your particular situation. This is why you should always consult a lawyer not random comments on the internet. Also because they spend years reading this stuff it explains why they are so expensive!
