In undertakings with at least fifty employees, where the redundancy project concerns at least ten employees within the same thirty-day period, any redundancy carried out in the absence of any decision relating to validation or homologation or where a negative decision has been issued shall be null and void.
In the event of cancellation of a validation decision referred to in Article L. 1233-57-2 or a homologation decision referred to in Article L. 1233-57-3 due to the absence or inadequacy of the job protection plan referred to in Article L. 1233-61, the redundancy procedure is null and void.
The first two paragraphs do not apply to companies in receivership or liquidation.
