Every government regulatory agency already does this. This is why we have millions of pages of regulations. For example (not exhaustive), the IRS, Immigration, and Labor departments lay out exactly how to follow the statutes, and set judicial precedent in their administrative courts. The flipside to this is that there is so much information that people don't know that their questions have already been answered.
