A Manhattan federal judge allowed Purdue Pharma on Friday to immediately appeal her ruling last month vacating the company’s $4.3 billion bankruptcy settlement agreement.

In a three-page order, U.S. District Judge Colleen McMahon of the Southern District of New York rejected arguments from a consortium of states that an interlocutory appeal to the U.S. Court of Appeals for the Second Circuit would delay resolution of Purdue’s Chapter 11 case.
