It is not just about open meetings. It is about with actually complying with how the regulations are adopted. If I understand correctly, if WDFW did not comply with APA and did not follow the law then none of the regulations were legal. Which could mean that people who were cited for violations have pretty good grounds to appeal. But a lawyer might know that better.

Open meetings are just part of the issue. Complying with the law is another as well as providing public documents.
