Anthem filed a petition asking the U.S. Supreme Court to review its merger with Cigna.
Here are four things to know:
1. The circuit court ruled against the deal, saying it would limit quality care for Americans and deny them medical costs savings.
2. Judge Brett Kavanaugh did not agree with the decision and wrote in his dissent, "the record evidence decisively demonstrates that this merger would be beneficial to the employer-customers who obtain insurance services from Anthem and Cigna."
3. In a release, Anthem states the court currently relies on merger precedents from the 1960s. Therefore, Anthem says these are outdated and officials should update them to depict " the modern understanding of economics and consumer benefit."
4. Anthem owes Cigna a $1.85 million breakup fee, as well as other potential liabilities, if the merger fails to pass.
