The annulment of elections because of vote-buying by incumbents has been one of the major causes of frequent by-elections in this legislative term. It is commendable that an increasing number of judges are willing to use judicial action to redress the trend of vote buying. However, in almost all vote-buying trials, the bribe receivers are given only light sentences, which is unhelpful to the rebuilding of moral values in Taiwanese society. Yet another controversial point in the present system is that those who have had their elections annulled are not required to return their campaign subsidies -- counted at NT$30 per vote -- to the national coffers. Unless we amend election laws to address such an unjust situation, the administration of President Ma Ying-jeou will have difficulty rebuilding its authority and credibility, and Taiwan's image as a just and democratic nation will also go to ruin. Another common situation that calls for a by-election is when incumbents run for other public offices in the middle of their terms. Whether restrictions should be imposed in this regard is an issue that both the ruling and opposition parties cannot evade.
