When a bond-issuing company's payment to a bondholder, settlement effected with a bondholder, or other act conducted against or with a bondholder is grossly improper, the bond administrator may demand rescission of relevant act by filing an action.

The action referred to in the preceding paragraph may not be filed when six months have elapsed from the time when the bond administrator learned about the fact that serves as the cause for the rescission of the act referred to in that paragraph. The same applies when one year has elapsed from the time of the act referred to in that paragraph.

In the cases prescribed in paragraph (1), if there is a resolution at a bondholders meeting, a representative bondholder or a resolution administrator (meaning the resolution administrator prescribed in Article 737, paragraph (2)) may also demand rescission of the act referred to in paragraph (1) by filing an action;provided, however, that this does not apply when one year has elapsed from the time of the act referred to in that paragraph.

The provisions of the proviso to Article 424, paragraph (1), Article 424-5, Article 424-7, paragraph (2), and Article 425 through Article 425-4 of the Civil Code apply mutatis mutandis to the cases referred to in paragraph (1) and the main clause of the preceding paragraph. In these cases, the phrase "from relevant act" in the proviso to Article 424, paragraph (1) of that Act is deemed to be replaced with "from the act prescribed in Article 865, paragraph (1) of the Companies Act", the phrase " that the obligee is prejudiced" in that paragraph is deemed to be replaced with "that relevant act is grossly improper", the phrase "the obligee is prejudiced" in each item of Article 424-5 of the Civil Code is deemed to be replaced with "that relevant act is grossly improper," and the term "obligees" in Article 425 is deemed to be replaced with "bondholders".
