The article initially analyzes judgments of election lawsuits from 2000 until 2012 in order to affirm that most election lawsuits filed are based on vote-buying, defamations during the election, fraudulent numbers of votes, and phantom voters as reasons. Focusing on those reasons, the author intends to review problems in Taiwan's election acts (the Civil Servants Election and Recall Act, the Presidential and Vice Presidential Election and the Recall Act) and trials of election lawsuits in the following. First, does the gift giving and entertaining by candidates form any suspicion of bribery to electors during a campaign? Second, is the dispute over election defamations too common in election lawsuits as the punishment is too light to deter such a behavior. Third, should we count potential votes in cases of a fraudulent number of votes? Fourth, if there are potential votes, can be the lawsuits of election invalidity and elected candidate invalidity both be filed simultaneously? Aiming to answer the above questions, the author provides the following suggestions. First, to referring to electoral laws in Japan and Korea, an article that forbids gift giving and entertaining by candidates for electors during a campaign can be added to Taiwan's election act. Second, intentionally fraudulent accusations aimed at celebrities and politicians are not covered under freedom of speech. Furthermore, the accusation harms the justice and values in elections. Thus, the author recommends adding a minimum punishment for election defamations of three months to six months in prison. The potential votes should be filed as the reason for the lawsuit of election invalidity instead of elected candidate invalidity. Fourth, in order to resolve the overlap in lawsuits, the election invalidity lawsuits should be filed prior to elected candidate invalidity lawsuits.
