It can be a cast-iron SOB to defeat large companies or corporations. In the late 60s (?), there was a lawsuit against PG+E in California. If I recall correctly, they had been overcharging customers. A political fellow (Brown?) took them to court and won. So, PG+E owed some incredible sum of money to its customers. They didn't have the money, so Nixon (yes, that one) allowed them to have a rate increase to pay back the customers. Gotta love it.
