Precedent based common law is stupid. A variant or something similar to the Napoleonic Code is better.
Why should judges effectively make laws, based on how they interpret a centuries old judgment about some medieval farmers and a sexy cow? Have the legislature legislate. Have judges judge if the law has been followed.
I don't think it's a huge coincidence that Common Law in the UK has arguably entrenched century old privileges and vestiges of aristocratic privilege and feudalism.
