Huge mistake by the school. The radio station will file what is called an anti-SLAPP motion, win it, and not only get the case dismissed but also get ITS ATTORNEYS’ FEES.
If not, it gets worse for the school, because the radio station will bury the school in “discovery,” finding out every tawdry, racist thing about the “academy” and make it even more of a laughingstock than it already is.
I don’t have any legal training, but it would seem to me that LAUSD would have had a say on whether or not this suit went forth based on its merits or lack thereof. After all, and as you mention, any judgment against the school is not coming out of Aguilar’s piggy bank.
