Jurisdiction and standing are adjudicated at every level by the court itself to ensure that the issues before the court can even be before the court.

[Robert DeLong]

The Supreme Court is the highest court of the land. Thus it has full jurisdiction to hear any case whatsoever. It can even take a case that has not traveled the chain of lower courts, just as it did when it took the Bush V Gore case on December 12, 2000.

It took on the Roe V Wade abortion case, even though every legal scholar of worth said it should have never taken the issue because it was rightfully a state issue, not a Federal issue.
