Lobbyists, attorneys and trade group representatives packed a Sacramento conference room Monday for the first public comment session on proposed rules for the California Consumer Privacy Act.

Only a handful of those in attendance, however, offered any public thoughts on the data privacy law that goes into effect Jan. 1. Most in the audience simply tapped notes on laptops or scribbled on legal pads. Organizers from the Attorney General's Office closed the meeting after about 90 minutes due to a lack of speakers.

That's not to say the law and the regulations that will guide its enforcement aren't controversial.
