The Wall Street Journal has an extensive profile on the Center for Class Action Fairness. (I should note that the problem with the Grand Theft Auto settlement was not so much that it provided "partial refunds" but that class members received under $30,000 while the attorneys were asking for a million dollars.) There's also a sidebar discussing the Blessing v. Sirius XM objection; CCAF's appeal of the settlement approval is pending in the Second Circuit.
