The US Constitution is the foundation for all of US law. Business and commerce are directly affected by the words, meanings, and interpretations of the Constitution. Because it speaks in general terms, its provisions raise all kinds of issues for scholars, lawyers, judges, politicians, and commentators. For example, arguments still rage over the nature and meaning of “federalism,” the concept that there is shared governance between the states and the federal government. The US Supreme Court is the ultimate arbiter of those disputes, and as such it has a unique role in the legal system. It has assumed the power of judicial reviewThe power the Supreme Court has to say what the US Constitution means. Because the Constitution speaks in broad terms, the interpretations of the Supreme Court as to the meaning of its provisions define what the Constitution means. The Constitution can only be changed by amendment or by further interpretation by the Supreme Court., unique among federal systems globally, through which it can strike down federal or state statutes that it believes violate the Constitution and can even void the president’s executive orders if they are contrary to the Constitution’s language. No knowledgeable citizen or businessperson can afford to be ignorant of its basic provisions.
