As underlined in the 2009 Report on the cancellation of election results, “[a]lthough the wording in legislation or case-law may vary, it may be said that in almost all countries the main criteria are that violations occurred in the election constituency during the conduct of voting or during the determination of the election results, that have made it impossible to determine the voters’ will, or that the irregularities and violations may have affected the election results.” Regarding the notion of violations, the 2009 Report states that “[c]ancellation of a mandate is meant as a consequence of a violation of electoral legislation or other legislation applicable to the electoral process, including noncompliance with rules on the eligibility to be elected. The possibility to cancel election results after the elected candidate has entered office may be limited to the most serious violations of electoral procedure, e.g. cases of criminal offences, while in some disputable and not so evident cases the cancellation is not allowed.”84 This includes serious irregularities and/or violations evidenced during the pre-electoral period and/or on election day, including during the pre- and post-voting operations.
