Code is both much smaller as a domain and less prone to the chaos of human interpretation. There are many factors that go into why a given civil or criminal case in court turns out how it does, and often the biggest one is not "was it legal". Giving a computer access to the full written history of cases doesn't give you any of the context of why those cases turned out. A judge or jury isn't going to include in the written record that they just really didn't like one of the lawyers. Or that the case settled because one of the parties just couldn't afford to keep going. Or that one party or the other destroyed/withheld evidence.
Generally speaking, your compiler won't just decide not to work as expected. Tons of legal decisions don't actually follow the law as written. Or even the precedent set by other courts. And that's even assuming the law and precedent are remotely clear in the first place.
