The basic principles relating to elections are subject to particular challenges when electronic voting methods are used. The Council of Europe continues to be the only organisation that has set intergovernmental standards in the field of e-voting. The Committee of Ministers Recommendation Rec(2004)11, which has been used in national jurisprudence even in non-member states, as well as by other relevant international actors, has recently been updated: a new recommendation – which consists of the actual Recommendation CM/Rec(2017)5 on standards for e-voting, the guidelines on the implementation of the provisions of the Recommendation with specific requirements and the Explanatory Memorandum – was drafted as an enhancement of Rec(2004)11 and deals with the most critical part of election technology, namely e-voting, which means the use of electronic means to cast and count the vote. This category includes systems such as Direct Recording Electronic (DRE) voting machines, ballot scanners, digital pens and internet voting systems. The Recommendation is aimed at ensuring that e-voting guarantees universal, equal, free and secret suffrage, and it includes provisions on organisational requirements, accountability, reliability and security of the system.
