Sitting in a hotel room and trying to catch up on threads. This one is interesting, as it has morphed from the UPOM lawsuit as the topic of the thread to a lot of other issues. I can't speak for others, but here is how it played out for me.
I emailed my attorneys when this lawsuit came out.
They reviewed the UPOM case, the claims asserted, then we scheduled a meeting. From that, this is the legal advice I got, paraphrased, "Looks like a lot of strong words, but nothing of real substance. Probably helps them in the upcoming election cycles and resulting legislative session. We don't recommend you spend your time, credibility, and money on legal fees to intervene. The poor quality of the case doesn't deserve the credibility of your intervention."
So, I did not intervene. From what I took of the meeting with the lawyer, this was more of a PR stunt (my words) by UPOM. Maybe that will turn out to be wrong if AG Knudsen and his staff roll over on what should be an easy case. But, when he analyzed the claims and applied the applicable law, he did not see much chance of success by UPOM.
As such, I was happy to pay $600 to be advised I don't need to waste thousands dollars more and weeks of my time to file as an intervener.
