This document that Hey_Porter mentioned is useful, but I haven't seen any analysis that takes the Portland ordinances that I mentioned and that ruling and figures out what exactly is allowed in Portland. Both sets of rules would apply.
Also, keep in mind that the AG office advice in a situation like this doesn't set rules per se; it gives the public a hint about what types of things the AG office is likely to prosecute and which things are "on the line" that it will probably ignore. An AG has a lot of issues to deal with, and they are going to decline to prosecute most of the time. Guidance publication is a way for the AG office to tell the public what's likely so far over the line that the AG can't ignore.
Ultimately the statues and local ordinances will govern. At this point, it's the city of Portland who is concerned and holding hearings about the local clubs, so in some sense, the OR law itself and AG's office opinion won't come into play unless the Portland City Council and its appointees want it to. The OR law clearly delegates the licensing power to local cities and counties, and as such, that's where the discussion is. If Portland revokes someone's license, the licensee can sue at the state level and claim Portland violated OR statue in some way, but given that the clubs operate now right on the line, I think the clubs would have a hard time showing that in a OR court.
The main problem in my view remains that players are not organized to write to the city council and raise the issue. Journalists treat the story with only passing interest. I wrote to the PPA to ask for help and they ignored my email. (Anne Rolm ignored my email too, so I suspect it's the only one she got about this issue.) If something is going to change, players locally have to get organized and let the city council know that we want the games to continue. (I'm surprised that the clubs aren't trying to encourage players to organize, but I suspect that's because they fear any such action will be looked upon as inappropriate by regulators and weaken their case.)
We can stand up on our own and speak and complain. We need a local organization that is initially run by volunteers (or maybe contributions from players). I'm busy with my day job and have no time to run it (plus, no one PM'd me to say they wanted to start one
, but I'd be willing to contribute advice and donate a few bucks.
Hey_Porter is right that Portland poker will probably disappear, but mainly because the city clearly sees it as an irritant with no popular support. If that equation is changed on either side, doomsday probably is not so imminent.
