in what ways does the magna carta still impact law?

Magna Carta has been perhaps the greatest influence on our
system of government and justice for all time. It's primary influence is that it
instituted the principle of "rule of law," that is that the law is above the whim or
will of any one person. Under Magna Carta, the King himself was subject to the law. In
the United States, the President of the United States or any other government official
is bound by the law. Secondly, the principle of trial by a jury of ones peers was
established. Although there are rare exceptions (juveniles, etc.) in almost every legal
proceeding one has the right to a trial by a jury of his peers, even for a simple
traffic ticket. Finally, the idea of parliamentary legislation was introduced, an idea
that is behind our United States Congress. It provides for laws to be passed by the duly
elected representatives of the people, not by a single individual. The importance of
Magna Carta can hardly be overstated.
