Bush v. Gore, 531 U.S. 98 (2000), was a landmark decision of the United States Supreme Court on December 12, 2000, that settled a recount dispute in Florida's 2000 presidential election between George W. Bush and Al Gore. On December 8, the Florida Supreme Court had ordered a statewide recount of all undervotes, over 61,000 ballots that the vote tabulation machines had missed. The Bush campaign immediately asked the U.S. Supreme Court to stay the decision and halt the recount. Justice Antonin Scalia, convinced that all the manual recounts being performed in Florida's counties were illegitimate, urged his colleagues to grant the stay immediately. On December 9, the five conservative justices on the Court granted the stay, with Scalia citing "irreparable harm" that could befall Bush, as the recounts would cast "a needless and unjustified cloud" over Bush's legitimacy. In dissent, Justice John Paul Stevens wrote that "counting every legally cast vote cannot constitute irreparable harm." Oral arguments were scheduled for December 11.

The Supreme Court of the United States (SCOTUS) is the highest court in the federal judiciary of the United States. It has ultimate appellate jurisdiction over all U.S. federal court cases, and over state court cases that turn on questions of U.S. constitutional or federal law. It also has original jurisdiction over a narrow range of cases, specifically "all Cases affecting Ambassadors, other public Ministers and Consuls, and those in which a State shall be Party." The court holds the power of judicial review: the ability to invalidate a statute for violating a provision of the Constitution. It is also able to strike down presidential directives for violating either the Constitution or statutory law.
