I think that is not true in general. Consider, for example, the charge of reckless driving. I think (although have no data) that there are probably more laws requiring human judgment than are based on strictly numerical criteria. Off the top of my head, the various degrees of murder, perjury, hate crimes, divorce settlements, and probate court. These all may have very specific criteria to meet them, but there is no way an algorithm could determine innocence or guilt. The only numerical laws I can think of are speed limits and the lines between grand theft / theft.
