The Indiana Supreme Court is weighing arguments to decide if the state is liable for some of the damages faced by a rigging company in the 2011 state fair stage collapse that killed seven people. The justices are hearing oral arguments in the state's appeal of a March Court of Appeals ruling involving Mid-America Sound Corp. That ruling found Indiana might be responsible for some legal damages faced by Mid-America, after high winds toppled the stage rigging onto fans awaiting the start of a concert by country duo Sugarland. Seven people were killed. Mid-America contends the state is financially responsible by contract for the cost of its defense and any judgments against it. Indiana says the State Fair Commission is a state entity that cannot be required to pay Mid-America's own liability.
