Explanation:

Easy cases are almost always resolved correctly by lower courts. If there doesn't appear to be a possibility of the lower court having made an error, the Supreme Court will decline to hear the case. Also, the Supreme Court has far too little time to hear every case sent to it, so it will tend to turn down cases that don't deal with important and difficult Constitutional issues.
