A federal judge on Thursday overturned a bankruptcy settlement for OxyContin manufacturer Purdue Pharma that would have protected its owners, the Sackler family, from future lawsuits relating to the opioid crisis.

U.S. District Judge Colleen McMahon ruled that the bankruptcy court lacked the authority to release the Sackler family from liability, Reuters reported. In September, U.S. Bankruptcy Judge Robert Drain approved the settlement plan, which would have resulted in the dissolution of Purdue Pharma and the transfer of its assets to a firm run by a trust and meant to combat the opioid crisis.
