The U.S. Supreme Court ruled in favor of the Town of Chester, holding a litigant seeking to intervene as of right under Federal Rule of Civil Procedure 24 must show Article III standing if the intervenor wishes to pursue relief not requested by a party. The Supreme Court remanded the matter to the Second Circuit to determine the specific relief sought by the intervenor and, if necessary, whether the intervenor has standing.

Steven Stern represents the Town of Chester in the litigation. Neal Katyal of Hogan Lovells in Washington, D.C. argued the case before the Supreme Court.
