Effects of a Judgment of Invalidation of a Share Exchange or Share Transfer
Article 844   In cases where a judgment upholding a claim relating to an action seeking invalidation of a Share Exchange or Share Transfer of a Stock Company has become final and binding, if the Stock Company acquiring all of the Issued Shares (hereinafter referred to as the "Former Wholly Owning Parent Company" in this Article) of the Stock Company effecting the Share Exchange or Share Transfer (hereinafter referred to as the "Former Wholly Owned Subsidiary Company" in this Article) has delivered the shares of the Former Wholly Owning Parent Company (hereinafter referred to as the "Shares of the Former Wholly Owning Parent Company" in this Article) at the time of the Share Exchange or Share Transfer, the Former Wholly Owning Parent Company must deliver to shareholders pertaining to the Shares of the Former Wholly Owning Parent Company as of the time such judgment became final and conclusive the shares of the Former Wholly Owned Subsidiary Company (hereinafter referred to as the "Shares of the Former Wholly Owned Subsidiary Company" in this Article) that had been held, at the time of the Share Exchange or Share Transfer, by the persons who received delivery of the Shares of the Former Wholly Owning Parent Company. In such cases, when such Former Wholly Owning Parent Company is a Share Certificate-Issuing Company, the Former Wholly Owning Parent Company may request such shareholders to return the old share certificates representing such Shares of the Former Wholly Owning Parent Company in exchange for the delivery of such Shares of the Former Wholly Owned Subsidiary Company.

前項前段に規定する場合には、旧完全親会社株式を目的とする質権は、旧完全子会社株式について存在する。

In the cases prescribed in the first sentence of the preceding paragraph, pledges on the Shares of the Former Wholly Owning Parent Company are effective with respect to the Shares of the Former Wholly Owned Subsidiary Company.

前項の質権の質権者が登録株式質権者であるときは、旧完全親会社は、第一項の判決の確定後遅滞なく、旧完全子会社に対し、当該登録株式質権者についての第百四十八条各号に掲げる事項を通知しなければならない。

When the pledgees with respect to the pledges set forth in the preceding paragraph are Registered Pledgees of Shares, the Former Wholly Owning Parent Company must, without delay after the judgment set forth in paragraph (1) became final and conclusive, notify the Former Wholly Owned Subsidiary Company of the matters listed in the items of Article 148 regarding such Registered Pledgees of Shares.

前項の規定による通知を受けた旧完全子会社は、その株主名簿に同項の登録株式質権者の質権の目的である株式に係る株主名簿記載事項を記載し、又は記録した場合には、直ちに、当該株主名簿に当該登録株式質権者についての第百四十八条各号に掲げる事項を記載し、又は記録しなければならない。

A Former Wholly Owned Subsidiary Company that has received a notice under the provisions of the preceding paragraph must, when it enters or records in the shareholder register the Information Required to Be Entered in the Shareholder Register in connection with the shares underlying the pledges of the Registered Pledgees of Shares set forth in that paragraph, immediately enter or record in the shareholder register the information listed in the items of Article 148 regarding such Registered Pledgees of Shares.

第三項に規定する場合において、同項の旧完全子会社が株券発行会社であるときは、旧完全親会社は、登録株式質権者に対し、第二項の旧完全子会社株式に係る株券を引き渡さなければならない。 ただし、第一項前段の株主が旧完全子会社株式の交付を受けるために旧完全親会社株式に係る旧株券を提出しなければならない場合において、旧株券の提出があるまでの間は、この限りでない。

In the cases prescribed in paragraph (3), when the Former Wholly Owned Subsidiary Company set forth in that paragraph is a Share Certificate-Issuing Company, the Former Wholly Owning Parent Company must deliver the share certificates representing the Shares of the Former Wholly Owned Subsidiary Company set forth in paragraph (2) to its Registered Pledgees of Shares; provided, however, that this does not apply until the old share certificates representing the Former Wholly Owning Subsidiary Company are submitted in cases where the shareholders set forth in the first sentence of paragraph (1) must submit such old share certifications in order to acquire the Shares of the Former Wholly Owned Subsidiary Company.
