Regulatory gaps in the electoral legislation undermine legal certainty. Even voluminous and detailed electoral legislation may lack clarity on several issues, such as, for instance, media and campaign regulations, dispute procedures, election observation, or the regulation of new electoral technologies. In fact, electoral observers consistently find out that certain areas of the electoral process are left under-regulated or poorly regulated in a number of countries. Even in long-established democracies, such gaps occur where the electoral law has not adapted to new developments. Thus, it should be examined whether the electoral legislation needs to be revised and modernised, also in democracies that are rich in tradition (like, for instance, the UK).
