Post-election lawsuits related to the 2020 U.S. presidential election

After the 2020 United States presidential election, the campaign for incumbent President Donald Trump and others filed 62 lawsuits contesting election processes, vote counting, and the vote certification process in 9 states (including Arizona, Georgia, Michigan, Nevada, Pennsylvania, and Wisconsin) and the District of Columbia.

Nearly all the suits were dismissed or dropped for lack of evidence or lack of standing, including 30 lawsuits that were dismissed by the judge after a hearing on the merits. Among the judges who dismissed the lawsuits were some appointed by Trump himself. Judges, lawyers, and other observers described the suits as "frivolous" and "without merit". In one instance, the Trump campaign and other groups seeking his reelection collectively lost multiple cases in six states on a single day. Only one ruling was initially in Trump's favor: the timing within which first-time Pennsylvania voters must provide proper identification if they wanted to "cure" their ballots. This ruling affected very few votes, and it was later overturned by the Pennsylvania Supreme Court.

Trump, his attorneys, and his supporters falsely asserted widespread election fraud in public statements, but made few such assertions in court. Every state except Wisconsin met the December 8 statutory "safe harbor" deadline to resolve disputes and certify voting results. The Trump legal team had said it would not consider this election certification deadline as the expiration date for its litigation of the election results.
