Figure 1. The Marriage Equality Act vote in Albany, New York, on July 24, 2011 (left), was just one of a number of cases testing the constitutionality of both federal and state law that ultimately led the Supreme Court to take on the controversial issue of same-sex marriage. In the years leading up to the 2015 ruling that same-sex couples have a right to marry in all fifty states, marriage equality had become a key civil rights issue for the LGBT community, as demonstrated at Seattle’s 2012 Pride parade (right).

If democratic institutions struggle to balance individual freedoms and collective well-being, the judiciary is arguably the branch where the individual has the best chance to be heard. For those seeking protection on the basis of sexual orientation, for example, in recent years, the courts have expanded rights, culminating in 2015 when the Supreme Court ruled that same-sex couples have the right to marry in all fifty states.[1]

The U.S. courts pride themselves on two achievements: (1) as part of the system of checks and balances, they protect the sanctity of the U.S. Constitution from breaches by the other branches of government, and (2) they protect individual rights against societal and governmental oppression. At the federal level, nine Supreme Court judges are nominated by the president and confirmed by the Senate for lifetime appointments. This provides them the independence they need to carry out their duties. However, court power is confined to rulings on those cases the courts decide to hear.[2]

How do the courts make decisions, and how do they exercise their power to protect individual rights? How are the courts structured, and what distinguishes the Supreme Court from all others? This chapter answers these and other questions in delineating the power of the judiciary in the United States.
