According to the ECtHR press release:

"The applicant, Mr Berhane Okubamichael Debru, is an Ethiopian national who was born in 1954 and lives in Vasteras, Sweden, after moving to Sweden in September 2017, having been granted a permanent residence permit as a recognised refugee. The applicant's wife and two daughters, then applied from Uganda, where the family had been living before his departure, for Swedish residence permits on the basis of their family ties.

Family reunification was refused on the ground that he, at the time of the application, failed to fulfil the “maintenance requirement” (minimum-income and accommodation requirement). Relying on Articles 8 (right to respect for private and family life) and 14 (prohibition of discrimination), the applicant complains that the refusal to grant his wife and children residence permits violated his right to respect for his family life. He also complains that, in the light of his age and state of health, the decision to refuse family reunification amounted to discrimination.

The court found no violation of Article 8 of the ECHR."
