The various comments complaining that Justices have violated this Code in the past are forgetting that modern law and society looks dimly on ex-post-facto rulemaking and such laws are in fact forbidden by the Constitution. Past actions are certainly not covered under a code that is promulgated as of today. Anyway, it looks like a step forward. It will be interesting to see if there is any movement from Congress should the Code be violated.
