Correction: An earlier version of this story mistakenly noted that revenue per lawyer (RPL) declined 6.7 percent in 2009; in fact, RPL increased by that percentage.

Dewey & LeBoeuf saw a dramatic drop in gross revenue in 2009 while profits per equity partner moved up 3.4 percent, the result of a 10 percent decrease in equity partner headcount, according to numbers released by the firm Friday.
