On March 25, 2013, The New York Times reported that the "world’s largest law firm," DLA Piper, had been accused by a former client of a "sweeping practice of overbilling." Internal correspondence from attorneys within—the former client alleged—evidenced the firm’s overbilling practices. Attorneys at the firm gloated in the emails that: "I hear we are already 200k over our estimate" and that the firm had "random people working full time on random research projects in standard ‘churn that bill, baby!’ mode."

The firm denied any wrongdoing, explaining that the emails were nothing more than an offensive and inexcusable effort at humor, but did not reflect any actual excessive billing practices at the firm.
