To be fair, there's sufficient of it publicly available (e.g. on https://www.bailii.org/) that you can easily disprove the conspiracy theory that laws and interpretations are "blatently inconsistent". In fact most judgments are very well thought through and carefully written and cited, because those that aren't tend to be appealed if they are establishing an important principle and getting it wrong. There just isn't enough publicly available to base a full legal AI assistant on.
