"Law is Code" on The Law Factory: french bills as git, opendata and dataviz - https://news.ycombinator.com/item?id=7817357 May 2014 (0 comments)
Version control for the public parts will make both public and secretive law-drafting better.
The complexity is in common law, not natural-language laws.
The U.S. Code and Code of Federal Regulations can be completely presented through a Git-like system. The complexity comes in when attaching court cases.
If transparency is the goal, the entire codebase for this should be public domain and not profitable. Otherwise there's a profit motive to rewrite history.
This makes sense for bills. It doesn't for laws. Once a bill is a law, it's the will of the Congress.
