The binding legal principles established are: (1) Once a petitioner pays the full amount of security for costs as fixed by the Chief Justice under section 168(3) of the Electoral Act, there is no requirement to furnish names and addresses of sureties; (2) Allegations of corrupt practices in election petitions must be proved beyond reasonable doubt, applying the same standard of proof as in criminal cases; (3) An election petition must demonstrate not merely that irregularities occurred, but that such irregularities materially affected the outcome of the election; (4) There is a presumption of validity of elections which courts must strive to sustain in the public interest, as it is the people, not courts, who decide elections; (5) Untested affidavits from interested witnesses, without cross-examination and without specification of how the alleged conduct affected their actual voting behavior, are insufficient to prove corrupt practices beyond reasonable doubt; (6) A returning candidate's reference to public facilities secured during a previous term constitutes legitimate campaigning rather than improper use of state resources.
