Windfall in the Windy City

The city of Chicago has opted to settle a legal dispute over pandhandling. So long as the pandhandlers are essentially being refunded their fines, it all sounds acceptable. But the lawyers' fees are listed as $375,000, or almost 4 times the amount the entire plaintiff class of ~5000 persons will receive. Since I can't imagine a court ever allowing such a disproportionate fee, it's obvious to me why the lawyers are anxious to settle upfront.
