Update, 7/2/13, 6:45 p.m. EDT: Holland & Knight Dallas executive partner James Chadwick and partner Michelle Suarez issued a joint statement in response to this news item.

"Unfortunately, some press reports have implied that the 12 partners in our group were among those counseled for unsatisfactory performance at Patton Boggs. That is not accurate. None of the lawyers now joining Holland & Knight were among those counseled. Our group was very successful at Patton Boggs and we expect to have continued success at Holland & Knight."

Patton Boggs warned 18 partners earlier this year that their performance was unsatisfactory, and that they needed to improve or find a new firm.

Now 17 partners are parting ways with Patton Boggs. But it is unclear whether these are the same ones who were put on notice. The departures mark the second time this year Patton Boggs has shed a significant number attorneys from its ranks.

In March, Patton Boggs announced it was laying off 30 associates and 35 staff members at the same time that Legal Times reported poor financial results for the firm.
