In today's society democratic elections play invaluable role in giving legitimacy to the political order. Constitutional courts are obliged to pay attention to its constitutional and lawful conducting, which may involve ruling on a number of problem that are not always easy to resolve. In this paper, after initial theoretical analysis of elections, an overview of Croatian electoral legislation is presented with reference to its previous application. Then, a number of problems in Croatian electoral legislation is outlined, all of them having affected the election results. Afterwards, the procedure of constitutional judicial review of electoral legislation is explained. Specifically, through examples of the European Court of Human Rights and other reputable foreign high courts, such as the Federal Constitutional Court of Germany, the Italian Constitutional Court and the US Supreme Court, I demonstrate how electoral problems have been dealt with by the judicial fora, both in recent times and further into the past. Ultimately, the paper is dedicated to the Constitutional Court of the Republic of Croatia and analyzes its interventions in regulating many problems that occurred in Croatian electoral legislation that proved to be more or less successful.
