Cleary Gottlieb Steen & Hamilton yesterday (25 June) took to the courts in a bid to overturn sanctions brought against the firm for improperly attempting to dissuade a witness from testifying, writes The American Lawyer.

Lawyers from the firm, led by managing partner Mark Walker, filled a number of the gallery seats in the 2nd US Circuit Court of Appeal as Cleary attempted to reverse a stinging sanctions order by Southern District of New York Judge Loretta Preska last August saying the firm had shown “a willingness to operate in the murky area between zealous advocacy and improper conduct” in attempting to interfere with the deposition of a non-party witness.
