Where the party which has lodged the appeal is opposed by another party and if the department whose decision is contested considers the appeal to be admissible and well founded, it shall rectify its decision.

The decision may only be rectified if the department whose decision is contested notifies the other party of its intention to rectify it, and that party accepts it within two months of the date on which it received the notification.

If, within two months of receiving the notification referred to in paragraph 2, the other party does not accept that the contested decision is to be rectified and makes a declaration to that effect or does not make any declaration within the period laid down, the appeal shall be remitted to the Board of Appeal without delay, and without comment as to its merit.

However, if the department whose decision is contested does not consider the appeal to be admissible and well founded within one month after receipt of the statement of grounds, it shall, instead of taking the measures provided for in paragraphs 2 and 3, remit the appeal to the Board of Appeal without delay, and without comment as to its merit.
