Mo. Rev. Stat. § 115.600: Recount or new election, procedure — petition by election authority.

The election authority, if convinced that errors of omission or commission have occurred on the part of the election authority, election judges, or any election personnel in the conduct of an election, may petition the circuit court for a recount or a new election and the court is authorized to order a new election if the evidence provided demonstrates that the irregularities were sufficient to cast doubt on the outcome of the election.
