I'm not sure which court decision you're referring to. I don't think there has been one on any of the large PG&E caused fires in the last couple years. It usually takes more than a few years, and whatever was in process on them is now tied up in bankruptcy. The only final decision I know about was for the gas line explosion in San Bruno in 2010. That ended up being settled for $90M which given PG&E's self-documented negligence and how many people were killed and houses burnt, is not unreasonable. (
Court OK's $9 million PG&E San Bruno explosion settlement) There were initially larger amounts but those usually get cut way down before they are final and get paid. Even the initial $565M would not be that much of a problem for the country's largest utility. $90M is pocket change.
PG&E declared bankruptcy last fall after there were two big fires they caused, the Camp fire in Paradise which killed 85 and the Tubbs fire in Sonoma the year before which killed 22 and was at the time the largest damage amount of any fire in California, at $1.2 Billion. PG&E saw the potential of similar costs from the Camp fire and are trying to get out of their responsibility. It's a real hardship for people burnt out in PG&E caused fires before 2017 who have been waiting to rebuild and whose payments are now frozen.
Cutting power, while it may be a temporary fix for the immediate problem, is not a real solution. PG&E is working on improving their clearing and their lines like I mentioned, they're just doing it decades later than they should have. Everyone up here wants PG&E to do more clearing. In the past their contract crews have been very lazy and did minimal work. A branch here, a branch there, "waiting for the supervisor" for the rest of the day. The ones they had out this summer did a lot more actual clearing.
