The Illinois Supreme Court is close to deciding a case that has thrown liquor taxes, gambling and thousands of jobs into the air.

The case involves a $31 billion public works program that lawmakers approved in 2009. They decided to pay for the construction by raising taxes on liquor and candy, as well as legalizing video gambling at bars and truck.

The projects have created construction jobs across Illinois.

Chicago Blackhawks owner Rocky Wirtz, a liquor distributor, challenged the law. An appeals court agreed with him that it violated a requirement that laws must be limited to just one topic.

The state Supreme Court is scheduled to rule Monday on whether the law followed the rules or must be thrown out.
