The largest law firms in the country are fiercely competitive, so it's notable when nearly 40 of them agree to sign on to a legal brief. That's what happened in an appellate case that could have eroded the attorney-client privilege—and the firms' lucrative white collar defense practices.

They breathed a collective sigh of relief earlier this month when the Sixth Circuit overturned a lower court ruling that would have forced FirstEnergy to turn over to its shareholders the results of internal investigations. The company hired Jones Day and Squire Patton Boggs to conduct the probes in response to a bribery scandal and later argued that the work was shielded by attorney-client privilege.

On today's episode of our podcast, On The Merits, reporter Roy Strom explains what happened in this case and why it represented such a threat to Big Law. He also gets into the reasons lawyers' hourly rates for white collar defense work can climb so high.
