This isn't a law. It's a concept of what constitutes "good cause." Stop acting like the states operate in a vacuum when it comes to UI. When you find enough states (I found three, and can post two more), that if you have to go to a hearing, board of review, or court, someone is going to accept the precedents from the other states and not reinvent the wheel.
No, they are bleeping not.
The different states' agencies (those involved in adjudication) have nice little regional meetings with the other states in their region where they share ideas, policies and precepts. They discuss some cases and go over the federal regs and decide what the new regs possibly mean. They look at some of each other's decisions within their regions, mostly to judge if the federal regulations are being followed, NOT to set precedent for future decisions just because one decision was made in one state, or because one state is tending one way or another on some particular issue. And that is just in their particular region. This is far far beyond anyone's ability to google old decisions and imagine stuff about how things work in an agency where they've never been.
And once again, we're taking a post about something else entirely and making it all about something that was never brought up by the original poster simply so we can verbally ...well... piddle around is a cleaner way to put it.
