That was exactly my reaction. If Bob Ferguson (WA AG) wanted to pursue such a case, he / the state would have standing - and as far as I know, the school board asking the state and getting other school boards involved in such a case would be the more powerful approach. This is Seattle though, with its particular political leanings, and/or it could also be a bit of a Hail Mary - do this to show frustration in hopes that the AG or similar parties will take action.
