The Illinois Supreme Court has ordered a lower-court judge to stop asking for permission to reopen a failed lawsuit against Philip Morris USA over the company’s light cigarettes, effectively putting an end to the high-profile litigation.

In the 4-2 ruling Wednesday, the high court offered no explanation for the two-paragraph order that Madison County, Ill., Circuit Judge Nicholas Byron stop asking the state’s 5th District Appellate Court whether he has authority to reopen the lawsuit.
