Final answer:
The United States Supreme Court, made up of nine justices who serve lifetime appointments, is a feature of the democratic system that ensures laws adhere to the Constitution's principles and protects against the tyranny of the majority. Although their appointment is influenced by the politics of nomination and confirmation, and their rulings may reflect certain political biases, their primary role is to interpret laws in an unbiased manner.
Step-by-step explanation:
The question as to whether the system of nine Supreme Court justices interpreting the law for over 330 million Americans constitutes democracy is complex. The function of the Supreme Court is grounded in the U.S. Constitution, which was designed to include checks and balances among the three branches of government: legislative, executive, and judicial. The nine justices on the Court are tasked with ensuring that laws and policies align with the constitutional framework, not necessarily to reflect a direct form of democracy, but rather to uphold the rule of law and protect minority rights from the potential tyranny of the majority, as highlighted in Alexis de Tocqueville's argument.
As the Court's rulings are made by lifetime appointees who are confirmed by the Senate after nomination by the president, there is a democratic element in their selection, although it is indirect. It is true that, historically, judicial decision-making has been influenced by the political leanings of the justices, reflecting the ideological biases that arise from the appointments made by different presidents. This underscores the importance of the appointment process itself as a reflection of the choices made by democratically-elected officials. Judges are expected to put their policy preferences aside and interpret the law and the Constitution impartially, although, as Justice John Paul Stevens has exemplified, this can lead to decisions that are personally regrettable.
Overall, the unique role the Supreme Court plays in interpreting law and its purposeful insulation from direct public influence is a feature of the U.S. democratic system designed to protect it from the ebb and flow of majority opinion, while also ensuring the laws remain faithful to the nation's founding principles.
