#1) How did rule of law influence our political systems?
The rule of law is the legal principle that law should govern a nation, as opposed to being governed by random decisions of individual government officials. It primarily refers to the influence and authority of law within society, particularly as a constraint upon behaviour, including behaviour of government officials. All government officers of the United States, including the President, the Justices of the Supreme Court, state judges and legislators, and all members of Congress, pledge first and foremost to uphold the Constitution. These oaths affirm that the rule of law is superior to the rule of any human leader. At the same time, the federal government has considerable discretion: the legislative branch is free to decide what statutes it will write, as long as it stays within its enumerated powers and respects the constitutionally protected rights of individuals.
