I won't say much about this case. It's a (relatively) high-profile UCL standing case from the California Supreme Court, so will get a decent amount of press elsewhere. No need for me to pile on.
But I did want to say two quick things. First, this is a really wonderful opinion by Justice Werdegar. One of her best, in my view, in the sixteen year she's been on the Court. The entire time I was reading it, I thought to myself: "Wow. Whoever's writing this is smart, and a really good writer. I wish I could do half as well." It's analytically solid. Extremely so. Second, on a related note, it really crushes Justice Chin's dissent. It's not even close. It's not that Justice Chin doesn't have a point. But it's largely a political one. If you care about law and legal analysis, in my opinion, it's not even a fight. So I thought it disappointing that Justices Chin and Corrigan would go the other way. Not perhaps unexpected, but disappointing nonetheless.
But let's focus on the positive. If you want to read a great example of a really good opinion, read Justice Werdegar's. It's incredibly solid. Extremely good.
