A Texas court has ordered the Choctaw Nation of Oklahoma to pay $10.9 million in damages to the families of two women who died in a bus accident on the way from Dallas to a casino in Durant.

“We respect the court system, but we feel there were errors,” said Waddel Hearn, a spokesperson for the Choctaw Nation. “We plan to appeal.”

The accident occurred in 2013, injuring dozens of senior citizens and killing three passengers, including Alice Stanley, 83, and Paula Hahn, 69, who were awarded damages by the Dallas County Court.

“This should be a clear message to Choctaw Nation that you really need to screen the charter bus companies you use to take people from Texas to your casino,” Frank Branson, the attorney for Stanley, said Monday after the verdict was issued.
