Lawyers who sued Volkswagen over its diesel emissions scandal could end up with a pretty good return on their investment: After being awarded $175 million in fees and costs, they are asking for an additional $125 million—and it appears there’s a good chance they’ll get it.

That means a total of nearly $350 million in fees and costs could end up going to the 22 law firms leading the emissions litigation. The case lasted about a year, mostly in settlement negotiations.
