I read the original motion for this, and it's a good read.
The government has some pretty big restrictions on binding regulations from agencies. Restrictions that make a lot of sense when you realize that most law is made by elected officials with constituents, ie representative democracy. Regulations aren't made like that, so you have a lot of rules to prevent abuse.
One of the restrictions is you need to have defined periods for public comment on new regulations. Which the FAA did not do, as I understand things. It just came up with new rules without following the defined regulatory process. If for no other reason then that, the UAV rules were invalid.
