Where judicial reorganisation is converted into judicial liquidation, there is no need to serve on the creditors’ representative (mandataire judiciaire) a formal demand to pay rent falling due after the judgment opening the judicial reorganisation, where such rent had previously been the subject of a formal demand served on the manager of the debtor company during the observation period; and since the action seeking a declaration that the termination clause has taken effect for non-payment of rent falling due after the judgment opening the insolvency proceedings was brought more than three months after that judgment, it is admissible.
