Article 37

1. Without prejudice to the faculty to refer a case to the Grand Board under Article 165(3) of Regulation (EU) 2017/1001, a Board of Appeal shall refer a case allocated to it to the Grand Board if it considers that it must deviate from an interpretation of the relevant legislation given in an earlier decision of the Grand Board, or if it observes that the Boards of Appeal have issued diverging decisions on a point of law which is liable to affect the outcome of the case.

2. All decisions on referrals of appeal cases to the Grand Board shall state the reasons for which the referring Board of Appeal or, as the case may be, the Presidium of the Boards of Appeal considers that this is justified, shall be communicated to the parties to the case and shall be published in the Official Journal of the Office.

3. The Grand Board shall, without delay, refer the case back to the Board of Appeal to which it was originally allocated if it believes that the conditions for the original referral are not, or no longer, met.

4. Requests for a reasoned opinion on questions on a point of law pursuant to Article 157(4)(l) of Regulation (EU) 2017/1001 shall be referred to the Grand Board in writing, shall state the questions of law of which the interpretation is sought, and may also state the Executive Director's view on the different possible interpretations as well as on their respective legal and practical consequences. The request shall be published in the Official Journal of the Office.

5. Where a Board of Appeal has to decide, in a case pending before it, on the same point in law that has already been raised in a referral to the Grand Board pursuant to Article 165(3) or Article 157(4)(l) of Regulation (EU) 2017/1001, it shall suspend the proceedings until the Grand Board has taken its decision or delivered its reasoned opinion.

6. Groups or bodies representing manufacturers, producers, suppliers of services, traders or consumers which can establish an interest in the result of a case on appeal or a request for a reasoned opinion brought before the Grand Board, may submit written observations within two months following the publication in the Official Journal of the Office of the decision of referral or, as the case may be, the request for a reasoned opinion. They shall not be parties to the proceedings before the Grand Board and shall bear their own costs.
