1. The board itself or the general meeting may declare the nullity of, or annul, defective resolutions of the board, at the request of any director, of the supervisory board or of any shareholder with voting rights, within one year of becoming aware of the irregularity, but not after three years have elapsed from the date of the resolution.

1 - O próprio conselho ou a assembleia geral pode declarar a nulidade ou anular deliberações do conselho viciadas, a requerimento de qualquer administrador, do conselho fiscal ou de qualquer accionista com direito de voto, dentro do prazo de um ano a partir do conhecimento da irregularidade, mas não depois de decorridos três anos a contar da data da deliberação.

2. The time limits referred to in the preceding paragraph do not apply where the general meeting is considering acts of directors; in that case the meeting may resolve on the declaration of nullity or the annulment even if the matter is not included in the notice of meeting.

2 - Os prazos referidos no número anterior não se aplicam quando se trate de apreciação pela assembleia geral de actos de administradores, podendo então a assembleia deliberar sobre a declaração de nulidade ou anulação, mesmo que o assunto não conste da convocatória.

3. The general meeting of shareholders may, however, ratify any voidable resolution of the board of directors or replace a void resolution with a resolution of its own, provided that it does not concern a matter within the exclusive competence of the board of directors.

3 - A assembleia geral dos accionistas pode, contudo, ratificar qualquer deliberação anulável do conselho de administração ou substituir por uma deliberação sua a deliberação nula, desde que esta não verse sobre matéria da exclusiva competência do conselho de administração.

#

4. Directors must not implement void resolutions or allow them to be implemented.

4 - Os administradores não devem executar ou consentir que sejam executadas deliberações nulas.
