Advisory opinions delivered
Belgium
On 14 December the ECHR delivered its advisory opinion in reply to a request submitted by the Conseil d’État of Belgium.
The request was submitted in the context of an application lodged by a security guard before the administrative judicial division of the Belgian Conseil d’État, seeking the annulment of a decision by the Ministry of the Interior to withdraw an identity card entitling him to work as a security or surveillance guard, on the grounds that he was in contact with individuals associated with the “scientific” strand of Salafism.
Finland
On 13 April 2023 the ECHR delivered its advisory opinion in reply to a request submitted by the Supreme Court of Finland.
The request concerned the issues that have arisen out of proceedings for the adoption of an adult.
France
On 13 July 2022 the ECHR delivered its advisory opinion in reply to a request submitted by the French Conseil d’État.
The request concerned the entitlement of landowners’ associations to withdraw their land from the territory of an officially approved hunting association (ACCA).

The Court held that States are not obliged to register the details of the birth certificate of a child born through gestational surrogacy abroad in order to establish the legal parent-child relationship with the intended mother, as adoption may serve as a means of recognising that relationship.
Requests for advisory opinion rejected
Slovakia
The Court has decided on 14 December 2020 to reject the request for an advisory opinion submitted by the Slovak Supreme Court concerning the independence of the current mechanism for assessing complaints against the police.
The ECHR considered that the points raised did not concern an issue for which the Slovak Supreme Court required guidance so that it could ensure respect for Convention rights in hearing and determining the case in question.
Estonia
On 19 February 2024, the Court has decided to reject the request for an advisory opinion submitted by a panel of the Criminal Chamber of the Supreme Court of Estonia.
The ECHR ruled that the request did not raise a “question of principle” as required by Protocol No. 16, i.e., a novel and/or complex question, since the particular issue was the subject of well-established case-law. The discontinuance of criminal proceedings by a public prosecutor amounted to neither a conviction nor an acquittal, and Article 4 of Protocol No. 7 was therefore not applicable in such a situation.
Romania
On 28 June 2024 the Court decided to refuse the request for an advisory opinion submitted by the High Court of Cassation and Justice of Romania.
The High Court had requested the ECHR to give an opinion on two questions concerning the interpretation of Article 6 (right to a fair hearing) of the Convention and Article 1 of Protocol No. 1 (protection of property) to the Convention. The Court decided not to accept the request, considering that it did not concern a question of principle, within the meaning of Article 1 § 1 of Protocol No. 16, warranting examination by the Court’s Grand Chamber. The Court’s case-law was well developed with regard to the questions asked, and several aspects of that case-law were judiciously cited by the requesting court in its decision to refer the matter to the Court.
Romania
On 16 December 2024 the Court decided to refuse the request for an advisory opinion submitted by the High Court of Cassation and Justice of Romania.
The High Court requested that the ECHR give an advisory opinion on two questions concerning (1) the applicability of Article 8 (right to respect for private and family life) and (2) the level of precision required of the domestic law which had served as the legal basis for the dismissal. The Court decided not to accept the request, considering that it did not concern a question of principle, within the meaning of Article 1 § 1 of Protocol No. 16, which warranted examination by the Grand Chamber. Presenting an overview of its relevant caselaw, the Court showed that the requesting court already had guidance on Convention issues when determining the case before it. It thus saw no reason to elaborate further on the existing principles.

The DH-BIO had asked the Court to provide an advisory opinion on two questions regarding the protection of the human rights and dignity of persons with mental disorders in the face of involuntary placement and/or treatment.
