Conclusion:
Noting that the Equal Protection clause guarantees individuals that their ballots cannot be devalued by "later arbitrary and disparate treatment," the per curiam opinion held 7-2 that the Florida Supreme Court's scheme for recounting ballots was unconstitutional. Even if the recount was fair in theory, it was unfair in practice. The record suggested that different standards were applied from ballot to ballot, precinct to precinct, and county to county. Because of those and other procedural difficulties, the court held that no constitutional recount could be fashioned in the time remaining (which was short because the Florida legislature wanted to take advantage of the "safe harbor" provided by 3 USC Section 5). Loathe to make broad precedents, the per curiam opinion limited its holding to the present case.
Rehnquist (in a concurring opinion joined by Scalia and Thomas) argued that the recount scheme was also unconstitutional because the Florida Supreme Court's decision made new election law, which only the state legislature may do.
Breyer and Souter (writing separately) agreed with the per curiam holding that the Florida Court's recount scheme violated the Equal Protection Clause, but they dissented with respect to the remedy, believing that a constitutional recount could be fashioned. Time is insubstantial when constitutional rights are at stake.
Ginsburg and Stevens (writing separately) argued that for reasons of federalism, the Florida Supreme Court's decision ought to be respected. Moreover, the Florida decision was fundamentally right; the Constitution requires that every vote be counted.
