Article 843Effects of a Judgment of Invalidation of a Merger or Company Split

①When a judgment upholding a claim relating to an action seeking invalidation of any one of the acts set forth in the following items becomes final and binding, the company that carried out relevant act is liable jointly and severally to perform the obligations assumed by the companies specified respectively in those items after the day on which relevant act became effective:

②In the cases prescribed in the preceding paragraph, the property acquired, after the day on which the acts set forth in the items of that paragraph became effective, by the companies specified respectively in those items is co-owned by the companies that carried out relevant acts; provided, however, that if the act set forth in item (iv) of that paragraph has been carried out by a single company, the property acquired by the company specified in that item is owned by the single company that carried out relevant act.

③In the cases prescribed in paragraph (1) and the main clause of the preceding paragraph, each company's portion of the obligations to be assumed referred to in paragraph (1) and share of co-ownership of property referred to in the main clause of the preceding paragraph are decided through discussion among the companies.

④If no agreement is reached in the discussion set forth in the preceding paragraph with regard to each company's portion of the obligations to be assumed referred to in paragraph (1) and share of co-ownership of property set forth in the main clause of the preceding paragraph, the court comes to a decision, in response to a petition by the companies, by taking into account the amount of property of each company as of the time the act set forth in any one of the items of paragraph (1) became effective and all other circumstances.
