Agreement on the withdrawal of the United Kingdom of Great Britain and Northern Ireland from the European Union and the European Atomic Energy Community

Article 174 U.K. Disputes raising questions of Union law

1. Where a dispute submitted to arbitration in accordance with this Title raises a question of interpretation of a concept of Union law, a question of interpretation of a provision of Union law referred to in this Agreement or a question of whether the United Kingdom has complied with its obligations under Article 89(2), the arbitration panel shall not decide on any such question. In such case, it shall request the Court of Justice of the European Union to give a ruling on the question. The Court of Justice of the European Union shall have jurisdiction to give such a ruling which shall be binding on the arbitration panel.

The arbitration panel shall make the request referred to in the first subparagraph after having heard the parties.

2. Without prejudice to the first sentence of the first subparagraph of paragraph 1, if the Union or the United Kingdom considers that a request in accordance with paragraph 1 is to be made, it may make submissions to the arbitration panel to that effect. In such case, the arbitration panel shall submit the request in accordance with paragraph 1 unless the question raised does not concern the interpretation of a concept of Union law, interpretation of a provision of Union law referred to in this Agreement, or does not concern whether the United Kingdom has complied with its obligations under Article 89(2). The arbitration panel shall provide reasons for its assessment. Within 10 days following the assessment, either party may request the arbitration panel to review its assessment, and a hearing shall be organised within 15 days of the request for the parties to be heard on the matter. The arbitration panel shall provide reasons for its assessment.

3. In the cases referred to in paragraphs 1 and 2, the time limits laid down in Article 173 shall be suspended until the Court of Justice of the European Union has given its ruling. The arbitration panel shall not be required to give its ruling less than 60 days from the date on which the Court of Justice of the European Union has given its ruling.

4. The first subparagraph of Article 161(2) and Article 161(3) shall apply mutatis mutandis to the procedures brought before the Court of Justice of the European Union in accordance with this Article.
