Less than a week after picking up a private equity team from Cooley on the West Coast, Sidley Austin is bulking up its East Coast operations, adding a pair of high-profile litigators from Quinn Emanuel Urquhart & Sullivan in New York.

Tai-Heng Cheng, who chaired Quinn Emanuel’s New York international arbitration practice, is joining Sidley as a partner in the Big Apple. Simon Navarro, who was of counsel at Quinn Emanuel, is making the move with Cheng, taking on an of counsel role at Sidley.
