一般而言，股東會議程所有議案資訊必須事前揭露給全體股東，提供股東充分資訊，其方能在充分瞭解下作成投票決定。惟我國公司法長久以來承認股東有臨時動議與議案修正之權利，允許出席股東就第一七二條第五項規定除外事項之其他一切事項，在股東會現場提出臨時動議或原議案之修正，此舉不但將形成股東會議程資訊之漏洞，復以實務一般認為只要未違反第一七二條第五項之規定，股東可以在現場以臨時動議提議召開股東臨時會針對法定除外事項進行決議，或在同一議題下，可以提出任何修正案，而架空第一七二條之一股東提案權制度所寓有之資訊揭露功能。在無法獲得充分資訊之下，股東應當如何行使表決權，尤其未出席股東以書面或電子方式事前行使表決權時，更是需要充分資訊，否則一旦面對臨時動議或議案修正時，其表決權將依法視為棄權，更進一步衍生出表決權操縱和應否親自出席之問題，橫生枝節，臨時動議與議案修正之突襲性問題，亟待解決。 因此，參考美國、日本、德國、英國、香港、韓國和中國大陸公司法制，公司法應明文要求將股東會議程之主要內容或要領記載於召集通知中，股東會不得就召集通知所未記載之議案進行決議，股東如欲發表任何意見，應循事前提案權提出，而非在現場提出臨時動議或議案修正突襲其他股東。因此，本文建議禁止在現場提出任何臨時動議或議案修正。 / Generally speaking, the agenda of general meeting, including all motions, should be disclosed to all shareholders of the company in advance of a general meeting to provide them with sufficient information to vote (informed voting). However, according to Taiwan Company Act, shareholders have right to move extemporary motions or amendments all but any items as set forth in §172(5) hereof at the meeting. This will not only come to be a loophole resulting from blank statements in a notice of a general meeting, but also sideline the information disclosure function by implication of shareholder proposal in §172-1, because the court hold that the shareholder are entitled to move an extemporary motion to call a meeting to make a resolution on exclusion items in §172(5), or any amendment under the same subject. Thus shareholders are unable to vote without sufficient information, especially who cast their vote through writing or electronic transmission without participating in person in advance of the meeting. In case of extemporary motions or amendments, shareholders who cast vote through writing or electronic transmission shall be deemed to withhold their voting power. This result would bring some issues of manipulation of voting power and whether shareholders who have cast their vote through writing or electronic transmission should participate in person afterwards or not. However, extemporary motions and amendments with surprising nature shall be or shall not be, that is the question. In order to deal with this problem, the main component or general nature of items in the agenda of a general meeting shall be stated in the notice, and only the items stated in the notice could be validly passed at the general meeting by referring to the Company Act of the U.S., Japan, Germany, U.K., Hong Kong, South Korea, and Mainland China. If shareholders are willing to express their opinions, they should propose to ask to put in the agenda in advance of the meeting, instead of moving extemporary motions and amendments to surprise the others. This study suggests that no extemporary motion or amendment shall be allowed to move at the general meeting.
