The correct answer is: "the right to interpret laws"
The Marbury v. Madison case led to a landmark US Supreme Court decision issued in 1803. Such decision establishes the principle of judicial review.
It enables the judiciary power to overthrow laws or goverment actions which, according to their interpretations, go against the US Constitution.
It is a case which contributed to set the boundaries between the three branches of power: legislative, executive and judiciary. It also defines a part of the system of checks and balances through which each power supervises the other two in order to ensure that none of them gathers enough power to overrule the others.
