本文共研究自二○○○年以後至二○一二年年底前，有關共同基金及連動債之訴訟共322件，並分析訴訟最終結果與投資人特質、主要爭點及法律主張間的關係，本文主要發現如下：首先，投資人之勝訴率不高，此代表銀行所面臨的法律責任風險相當低；其次，就連動債糾紛，向訴訟外紛爭解決機制尋求救濟未必較有利；其三，由於資訊有限，本文尚無法證明法院對具若干特質的投資人就較有利；其四，除主張契約未成立外，原告勝訴率未因主張不同爭點而有明顯差異，但規範上應就銀行銷售產品後之義務方面作進一步澄清；其五，本文未發現若原告舉出特定的請求權基礎或訴訟策略，和訴訟結果間有統計上顯著的關係，亦無證據證明引用多個法律依據即可增加投資人勝訴的機會。

This study analyses the results of 322 lawsuits regarding retail mu-tual funds and structured notes in Taiwan between 2000 and 2012 and their relationship with other factors such as investors’ personal charac-teristics, main arguments and causes of action. This study has the fol-lowing major findings: (1) the winning rate for investors was quite low, meaning that banks face low legal risk from inappropriately selling claims; (2) investors were not better off for having filed a complaint with the Banker’s Association; (3) we have not proved that the courts showed preference for investors with certain personal traits due to the limited information available; (4) a plaintiff’s winning rate does not vary much from one argument to another, except for arguing formation of contract, but our research shows that more might have to be done to clarify the post-contractual responsibilities of banks; (5) there is also no proof to indicate that certain causes of action or litigation strategies would help investors in winning a judgment and we have not proved that filing more causes of action would help to increase a plaintiff’s chance of winning. Our findings urge regulators and legislators to recon-sider regulatory policies for investor protection as well as dispute resolu-tion for financial consumers in the future to offer more complete pro-tection of financial consumers.
