Can you please cite a specific US Supreme Court case or cases that President Lincoln deliberately ignored. Didn't President Jackson state in regards to a US Supreme Court decision regarding the removal of the Cherokee Indians something to the effect " it's their decision let them enforce it". Maybe @jgoodguy knows of that case.You are mistaken. An American president is bound by a federal court's decision. He may appeal, but this is how it works. He doesn't get to ignore the Court once a decision is rendered.
Oh, except Lincoln.
