“[Lowey Dannenberg] has considerable experience in litigating ‘some of the largest class actions throughout the country.’ . . . . The quality of their representation is also evidenced by the fact that Class Members, including sophisticated institutional investors, have not objected to the Settlement. The Court has no reason to doubt the quality of their representation.”

Hon. Gregory H. Woods, July 7, 2022 Fairness HearingTranscript, at p. 24 in In re JPMorgan Precious Metals Spoofing Litigation 18 Civ. 10356 (S.D.N.Y.)

“The court appreciates class counsel’s taking on these challenges and class counsel’s able navigation of these hard problems, in developing the case on behalf of the putative class, and in bringing contentious settlement negotiations to a successful outcome.

I might add too that the settlement was not only successful. Compared with many analogous cases, it was also prompt, a fact that brings obvious advantages to the class.”

Hon. Paul Engelmayer, May 31, 2022 Fairness Hearing Transcript, at p. 30 in In re JPMorgan Treasury Spoofing Litigation, 20 Civ. 3515 (S.D.N.Y.)
