I hope the following definition of a corporation clears this up for you Cologal. In any event the decision was written by Justice Kennedy. Try to find one written by Scalia, Roberts, Alito or Thomas to rebut the original point. You're in left field here.

"What Does Corporation Mean?
A legal entity that is separate and distinct from its owners. Corporations enjoy most of the rights and responsibilities that an individual possesses; that is, a corporation has the right to enter into contracts, loan and borrow money, sue and be sued, hire employees, own assets and pay taxes.

The most important aspect of a corporation is limited liability. That is, shareholders have the right to participate in the profits, through dividends and/or the appreciation of stock, but are not held personally liable for the company's debts."
