Yeah I'm really glad we don't have common law where I live. It makes the law way too complicated by having all these precedents play a role. If the law is not specific enough we just fix it.

Also it breaks the trias politica in my opinion. Case in point: the way the Supreme Court plays politics in the US. It shouldn't really matter what judge you pick, their job is to apply the law. But it matters one hell of a lot in the US and they've basically become legislators.
