Until a law is passed, my understanding is that it's status quo right now. What this may do is put guys like Warther out of business. And by out of business, I mean he might sell out everything he's got in his warehouse by the end of this week. As proposed, you'll still be able to order a cue from a maker, you'll just have to go there to pick it up in person. Everything ivory that's used in cues now anyways is legal pre-ban ivory, with the correct paperwork. Cuemakers should be getting (or are definitely able to get) the origin documents if they purchase from legit sources like Warther.
I'm sure there will be more to come on this down the road....think of this as just the first chapter of a book.
