Throughout the history of the United States government, the judiciary has evolved and changed over time. Specifically, the United States Supreme Court has arguably evolved the most, changing its motivations and philosophies over time as the country around it has evolved. Furthermore, the amount of external political influence of the Supreme Court has also increased as courts have begun to modernize over time along with people's ideas and views, all while trying to keep the judiciary within the scope of the Constitution and law . Historically, the United States Supreme Court developed in three key periods, and the way the Supreme Court developed in these three eras helped shape the judiciary into what it is today: a judicial body sensitive to political issues through the interpretation of the law and the Constitution as a living organism. And while the Supreme Court, through judicial activism, considers political issues, issues beyond their scope under the Constitution, it maintains impartiality by following the framework of the Constitution.

Madison, the Supreme Court ruled that the Judiciary Act of 178... at the center of the paper... is a problem. As the Courts modernized, their acceptance of external political influence also increased. This has been seen to develop in the transition period of eras, such as the move to the nine-year bailout in 1937 and the reversal of the separate but equal doctrine, and even in modern times with the legalization of same-sex marriage . While the Supreme Court is insulated from outside political influence by design, the modernization of the Court has caused leaks over time to address the evolving way the Constitution is to be interpreted, slowly allowing outside political influences to at least be addressed by the Supreme Court. Supreme Courts. Thus it can be argued that the Supreme Court is immune to external political influences by design, but as it has developed throughout history, its evolution has made it necessary to address external political influences to shape the court..
