county, the nature of the allegation being made, the remedy being sought, and the nature of the
evidence to be introduced at trial.75 There is no international consensus as to which standard must be
met in order to prove electoral fraud, malfeasance or criminal malpractice.76 However, there are three
standards that are typically applied in election cases: preponderance of the evidence, evidence beyond a
reasonable doubt, and clear and convincing evidence.77
Preponderance of evidence
One party has offered evidence that seems more
likely to be true than not.
Clear and convincing evidence
Evidence must show that it is substantially more
likely than not that the asserted claim is true.
Evidence beyond a reasonable doubt
Evidence of such a convincing character that one can
rely and act upon it without hesitation.
“Preponderance of the evidence” is also called “greater weight of the evidence” or “balance of
probabilities,” and is the idea that one party has offered evidence that seems more likely to be true than
not.78 When considering evidence under this standard, there must be a greater than 50 percent
likelihood in support of a particular question of fact. This is the general standard that is applied to civil
actions in many, if not most, legal systems.79 Since election complaints are usually treated as civil cases,
some jurisdictions may apply this standard to election disputes. It is debatable, however, whether the
preponderance of evidence standard is appropriate in a case considering annulment of an election.
Given the importance of speedy determination of election results and the potential costs associated
with nullification, the public interest might best be served by a higher standard of proof.
On the other end of the spectrum, evidence beyond a reasonable doubt is generally the standard that
must be met by the prosecution in a criminal case, but on rare occasions it is applied in civil cases. Under
this standard, the applicant is required to introduce evidence of such a convincing character that one can
rely and act upon it without hesitation. It does not, however, mean absolute certainty.80 In at least one
U.S. election case, the court applied a beyond a reasonable doubt standard when a stricter standard than
preponderance of the evidence was required.81 Using a reasonable doubt standard in election cases may
be appropriate when the remedy is being sought in conjunction with criminal prosecution. The U.K. and

Lord Denning indicated in Miller v. Minister of Pensions that beyond a reasonable doubt does not “need to reach
certainty, but it must carry a high degree of probability. Proof beyond a reasonable doubt does not mean proof
beyond the shadow of a doubt.” Miller v. Minister of Pensions, [1947] 2 All E. R. 372, 372-74.
