The CJEU (Grand Chamber) delivered on 21 December 2021 its judgment in case C‑124/20 (Bank Melli Iran v Telekom Deutschland GmbH), which is about Regulation (EC) No 2271/96 (Protection against the effects of the extraterritorial application of legislation adopted by a third country):

« 1. The first paragraph of Article 5 of Council Regulation (EC) No 2271/96 of 22 November 1996 […] must be interpreted as prohibiting persons referred to in Article 11 of Regulation No 2271/96, as amended, from complying with the requirements or prohibitions laid down in the laws specified in the annex to that regulation, even in the absence of an order directing compliance issued by the administrative or judicial authorities of the third countries which adopted those laws.

2. The first paragraph of Article 5 of Regulation No 2271/96, as amended by Regulation No 37/2014 and Delegated Regulation 2018/1100, must be interpreted as not precluding a person referred to in Article 11 of that regulation, as amended, who does not have an authorisation within the meaning of the second paragraph of Article 5 of that regulation, as amended, from terminating contracts concluded with a person on the Specially Designated Nationals and Blocked Persons List, without providing reasons for that termination. Nevertheless, the first paragraph of Article 5 of the same regulation, as amended, requires that, in civil proceedings relating to the alleged infringement of the prohibition laid down in that provision, where all the evidence available to the national court suggests prima facie that a person referred to in Article 11 of Regulation No 2271/96, as amended, complied with the laws specified in the annex to that regulation, as amended, without having an authorisation in that respect, it is for that same person to establish to the requisite legal standard that his or her conduct was not intended to comply with those laws.

3. Regulation No 2271/96, as amended by Regulation No 37/2014 and Delegated Regulation 2018/1100, in particular Articles 5 and 9 thereof, read in the light of Article 16 and Article 52(1) of the Charter of Fundamental Rights of the European Union, must be interpreted as not precluding the annulment of the termination of contracts effected by a person referred to in Article 11 of that regulation, as amended, in order to comply with the requirements or prohibitions based on the laws specified in the annex to that regulation, as amended, even though that person does not have an authorisation, within the meaning of the second paragraph of Article 5 of the same regulation, as amended, provided that that annulment does not entail disproportionate effects for that person having regard to the objectives of Regulation No 2271/96, as amended, consisting in the protection of the established legal order and the interests of the European Union in general. In that assessment of proportionality, it is necessary to weigh in the balance the pursuit of those objectives served by the annulment of the termination of a contract effected in breach of the prohibition laid down in the first paragraph of Article 5 of that regulation, as amended, and the probability that the person concerned may be exposed to economic loss, as well as the extent of that loss, if that person cannot terminate his or her commercial relationship with a person included in the list of persons covered by the secondary sanctions at issue resulting from the laws specified in the annex to that regulation, as amended ».
