and Resolving Disputes in Elections
was at stake. Such dismissals of legitimate claims can lead to a major
distrust in the electoral process.
Ultimately, the choice of standard of proof often depends on the rules of
procedure of a country’s legal system. In some countries, the law does not
make any distinction between administrative or criminal claims and thus,
the standard of proof remains the same regardless the specific nature of
the dispute. Thus, varying standards of evidence may be used in election
complaint adjudication around the world. A uniform standard will probably
not be adequate to handle every type of electoral complaint, and it can be
dangerous to impose one standard over the others. In light of these considerations, a complaints adjudication entity should be prepared to require
differing thresholds for evidence that the petitioner must provide depending
on the nature of the claim at stake.198 For example, there is a great difference
between a case in which a complainant argues to overturn a nationwide
election result, and a claim of ballot stuffing in an isolated precinct, and the
standards of evidence required for those claims might reflect those practical
differences. The choice of what standard to apply to each type of electoral
complaint might be made by the electoral management body, set by legislation, or even mandated in a national constitution. Regardless, the exact
standard to be applied in any particular case should be established in advance of the hearing rather than chosen by the arbiter on an ad hoc basis.199
The level of flexibility permitted within a defined standard will depend on
the type of complaint at issue. As noted by Lord Denning in Bater v. Bater,
a civil court considering a charge of fraud will naturally require a higher
degree of probability than it would require if considering a charge of negligence. For example, in its judgment on the 2001 Zambian presidential
elections petition against President Levy Mwanawasa, the Supreme Court
of Zambia referred to its previous case of Lewanika v. Chiluba, which affirmed that “it cannot be seriously disputed that Parliamentary Election
Petitions have generally long required to be proved to a standard higher
Bater v. Bater, [1951] P. 35, 37 (C.A.) (U.K.) (“The degree of probability in civil cases
depends on the subject matter in question.”). Similar reasons were used in support of the
criminal standard later in Preston-Jones v. Preston-Jones, [1951] A.C. 391, [1951] 1 All E.R.
124 (H.L.) (U.K.) (determining legitimacy of a child in petition for divorce based on adultery
claim); see also, In re Doherty, House of Lords, [2008] UKHL 33 (appeal taken from N. Ir.).
