A Nevada judge on Thursday denied an attempt to unseal a private investigator’s report in a wrongful termination case against casino company Las Vegas Sands Corp., Sands China Ltd. and the companies’ chairman Sheldon Adelson.

The ruling came after Guardian News & Media, the Campaign for Accountability and the union Unite Here argued that the public should see the exhibit that the groups say may tie the companies to organized crime in Asia.

The exhibit is part of the ongoing wrongful termination lawsuit filed by former Sands China CEO Steven Jacobs against the company and Adelson nearly five years ago.
