CHICAGO — West Virginia, Louisiana and Illinois are the three worst states in perceived fairness to sued businesses, according to a survey released Thursday. It says Delaware, Vermont and Nebraska are the three best.

Among those attending an unveiling of the 2015 Lawsuit Climate Survey in Chicago was Gov. Bruce Rauner, who said the state’s legal environment was hindering his ability to recruit businesses and grow jobs.

The survey, based on interviews with 1,200 attorneys and executives at companies with at least $100 million in annual revenues, was conducted for the pro-business U.S. Chamber Institute for Legal Reform. Seventy-five percent of respondents said a state’s litigation environment is likely to influence business decisions, including where to locate.

Later Thursday, the president of the Illinois Trial Lawyers Association blasted the survey – and Rauner’s association with it.

“It’s a form of math-washing – using numbers to give the veneer of science and precision to a biased study that found just what it wanted to find,” Perry Browder said.
