Separate lawsuits have been filed by the Chickasaw and Choctaw nations against insurance companies seeking judicial rulings that financial losses to casinos and other businesses caused by the COVID-19 pandemic are covered by business interruption policies.

A report in The Oklahoman on the known specifics of the suits states that the insurers have not specifically denied that these are covered losses, but similar denial of losses have happened in Louisiana (in Cajun Conti, LLC, et al. v. Certain Underwriters at Lloyd's London, et al., Civil District Court for the Parish of Orleans, Louisiana; which you can read about here) and in other locations.

Where insurers have denied claims, they have taken the stance that since no physical damage has occurred to the property, no covered losses have actually occurred.
