Have you looked at the Electronic Code of Federal Regulations? It's usually up to date within a day or so of the current date.

Do you have any idea how Federal Regulations are made? You may have noticed threads about pullinjg CVRs to check pilots or requiring F/Os to have ATPs. Are they doing that yet?

All that being said, many airlines put restrictions above and beyond what the FAA requires. However, a GOM is normally an accepted manual and not an approved manual so it's hard to argue it has the force of law.
