I'm with on the idea that, on the surface, it feels lopsided - $142,000 in sanctions vs. $489,000 in defendant's legal fees - but AFAIK sanctions are not related to defendant's legal costs. You're trying to tie two unrelated concepts and getting twisted that they aren't more inline with each other. Sanctions, in most cases, are regulated - there's a minimum and maximum - whereas defendant's legal fees are not. The judge hopefully gave the maximum sanctions available.
I understand that sanctions are not related to defendant's legal costs.
I think they should be, because I think it's a joke that sanctions can be far less than what the defendant had to risk to fight the behaviour that caused the sanctions.
