Taiwan's Money Laundering Prevention and Control Act defines money laundering as covering up, hiding, receiving, or transporting "illicit gain." If investigators are unable to prove that the money wired abroad by Chen Shui-bian was obtained illegally, the most they can do is slap him with an administrative fine for inaccurate reporting of unspent campaign funds.
此外，根據台灣的洗錢防制法規定，「洗錢」的定義是掩飾、隱匿、收受、搬運「犯罪所得」，如果調查單位無法證明陳水扁匯出境外的資金來源為不法所得，而只是選舉結餘款申報不實，那麼最多也只能行政罰款了事。
