第八百四十一条(自己株式の処分の無効判決の効力)
Article 841Effects of a Judgment of Invalidation of Disposition of Treasury Shares
When a judgment upholding a claim relating to an action seeking invalidation of a disposition of treasury shares becomes final and binding, the relevant stock company must pay, to shareholders of relevant treasury shares as of the time relevant judgment became final and binding, monies equivalent to the amount of payment received from them or the value of the property delivered by them as of the time of the delivery. In these cases, when relevant stock company is a share certificate-issuing company, the stock company may request relevant shareholders to return the old share certificates representing relevant treasury shares in exchange for the payment of relevant monies.
The provisions of paragraphs (2) through (6) of the preceding Article apply mutatis mutandis to the cases set forth in the preceding paragraph. In these cases, the term "shares" in paragraph (4) of that Article is deemed to be replaced with "treasury shares".
前条第二項から第六項までの規定は、前項の場合について準用する。この場合において、同条第四項中「株式」とあるのは、「自己株式」と読み替えるものとする。
定義第八百四十条第一項・この節の中だけ
前条の規定により効力を失った株式に係る株券
わかりやすく言うと
新株発行の無効などを認める判決が確定したことで、将来に向かって効力を失った株式について発行されていた株券のことです。会社は、払込金額などに当たるお金を支払うのと引き換えに、その返還を求めることができます。
