Quinn Emanuel Urquhart & Sullivan and Foley & Lardner are squabbling over a bid to depose Foley chairman and CEO Daljit Doogal as part of a long-running dispute between the Am Law 100 firms over millions in fees stemming from work performed on the LeClairRyan bankruptcy.

In a Monday filing in the U.S. Bankruptcy Court for the Eastern District of Virginia, attorneys for Foley & Lardner sought a protective order to quash the deposition, calling Quinn Emanuel’s demand a “transparent attempt to annoy, harass, and place an undue burden” on the firm and its CEO. Meanwhile, Quinn Emanuel contended in its own filing that Foley & Lardner’s motion for a protective order came far too late and said there was merit to forcing Doogal to sit for a deposition currently scheduled for Thursday afternoon.
