Which case determined that standardless manual recounts violate the Equal Protection Clause?

The case that determined that standardless manual recounts violate the Equal Protection Clause is indeed Bush v. Gore. This landmark Supreme Court case arose during the contentious 2000 presidential election and addressed the issue of a controversial manual recount of votes in Florida. The Court found that the lack of consistent standards in the recount process could lead to unequal treatment of voters, thus violating the Equal Protection Clause of the Fourteenth Amendment.

This ruling highlighted the importance of equal treatment in electoral processes, asserting that all ballots must be treated equally to uphold the principle of fairness in democracy. The outcome of this case had significant implications for election law and the integrity of voting procedures across the United States, demonstrating how the legal system addresses matters of fairness and equality within the electoral context.
