Despite a resounding recent setback before an appeals court, BP PLC remains unbowed in its campaign to rewrite its $9.6 billion settlement in the Deepwater Horizon disaster. The company continues to chip away at the deal both in the courts of law and of public opinion. Even hard-bitten plaintiffs attorneys who have taken on big oil companies in the past are finding it remarkable for a company to challenge its own settlement.

In court, BP has objected to the way the deal’s scope and compensation methods have been interpreted. It’s also opposing disbursements to thousands of seafood businesses and claims made by nonprofits that the company says aren’t covered by the settlement.
