The Texas Supreme Court agreed Friday to review a lower court’s holding that Anadarko Petroleum Corp. is not entitled to coverage by Lloyd’s of London underwriters for any of the over $100 million it has spent defending against claims stemming from the 2010 Deepwater Horizon explosion and oil spill.

In a brief notice, the Texas justices indicated they had granted Anadarko’s petition for review in the long-running coverage dispute. The oil and gas explorer, which was a minority partner in the offshore well where the blowout occurred, is seeking to upend a November 2016 decision by a Texas Court of Appeals panel in Beaumont that absolved the underwriters of any duty to cover Anadarko’s whopping defense bill.
