Selendy & Gay, a litigation focused firm launched just over a year ago, has picked up top appellate lawyer Caitlin Halligan, a former solicitor general for the state of New York. She joins as a partner from Gibson, Dunn & Crutcher.

An announcement Monday from Selendy & Gay hailed Halligan's arrival at the firm, where she becomes the 13th partner.

Halligan has served as counsel of record in at least 45 U.S. Supreme Court cases, including six in which she argued at the country's high court. She has also worked in prominent positions at the New York attorney general's office and the New York County district attorney's office, and most recently served as a partner and co-chair of Gibson Dunn's appellate and constitutional law practice.
