According to the summary provided by the EUAA Courts and Tribunals Network:

"The Council of State ruled that article 15 of Directive 2013/32/EU, that provides the possibility for an applicant for international protection to have a personal interview with the decision authority conducted by a person of the same sex and be assisted by the interpreter of the same sex, does not apply to the jurisdiction appeal procedure. It also ruled that the European Court of Justice, in its decision C-517/17, Milkiyas Addis v Germany of 16 July 2020, clearly stated that the court before which an appeal is lodged against a decision of inadmissibility of a subsequent application for international protection must comply with the guarantees laid down in Article 15 of Directive 2013/32 only if the applicant was not given an opportunity to be heard before the decision authority in accordance with the guarantees provided for by that article.  

Since the applicant had been heard before the decision authority in the presence of a female interviewer and female interpreter after submitting a third application for international protection, the appeal procedure before the Council for Alien Law Litigation did not need to comply with the safeguards provided in article 15."
