The issues have been meaty, and controversial, especially here in the middle of America. Iowa has been a leader with landmark rulings on slavery, school desegregation and gay marriage. But Friday, the Supreme Court passed up the opportunity to add to its legacy. In time, history will tell us just how far reaching this latest decision turns out to be, legally and environmentally.
