 The Supreme Court has struck down the bankruptcy plan for Purdue Pharma, which included a multibillion-dollar settlement for victims of opioid addiction. Justices ruled the bankruptcy could not shield Purdue Pharma owners, the Sackler family, from additional litigation. In a separate case, the court limited the Securities and Exchange Commission's use of in-house administrative courts. The ruling is seen as a major blow to the regulatory power of federal agencies.
