1. The Board of Appeal shall reject an appeal as inadmissible in any of the following events:

(a) where the notice of appeal has not been filed within two months of the date of notification of the decision subject to appeal;

(b) where the appeal does not comply with Articles 66 and 67 of Regulation (EU) 2017/1001, or with those laid down in Article 21(1)(d) and Article 21(2) and (3) of this Regulation, unless those deficiencies are remedied within four months of the date of notification of the decision subject to appeal;

(c) where the notice of appeal does not comply with the requirements laid down in Article 21(1)(a), (b), (c) and (e), and the appellant has, despite having been informed thereof by the Board of Appeal, not remedied those deficiencies within the time limit specified by the Board of Appeal to that effect;

(d) where the statement of grounds has not been filed within four months of the date of notification of the decision subject to appeal;

(e) where the statement of grounds does not comply with the requirements laid down in Article 22(1)(a) and (b), and the appellant has, despite having been informed thereof by the Board of Appeal, not remedied those deficiencies within the time limit specified by the Board of Appeal to that effect or has not submitted the translation of the statement of grounds within one month of the date of the submission of the original statement in accordance with Article 22(2).

2. Where the appeal appears to be inadmissible, the chairperson of the Board of Appeal to which the case has been allocated pursuant to Article 35(1) may request the Board of Appeal to decide without delay on the admissibility of the appeal prior to the notification to the defendant of the notice or of the statement of grounds, as the case may be.

3. The Board of Appeal shall declare an appeal as deemed not to have been filed where the appeal fee has been paid after the expiry of the time limit set out in the first sentence of Article 68(1) of Regulation (EU) 2017/1001. In such a case, paragraph 2 of this Article shall apply.
