The recent judgment of Iyilik v. Turkey concerns competing interests of an applicant and his (legal) daughter in a paternity case. The wife of the applicant, Mr. Iyilik, had given birth to a daughter in 1966. Mr. Iyilik denied being the biological father and a year later the couple divorced. Mr. Iyilik then brought proceedings to contest his paternity. Blood tests, the only available tests at the time, were taken. The results showed that Mr. Iyilik could be the father, just as any other man with the same blood type could be. The domestic courts consequently denied his request for contestation of paternity. In 2002, Mr. Iyilik submitted a new complaint, requesting reopening of the file and re-examination of his paternity in light of new scientific developments, i.e. the possibility of undergoing a DNA test. In pursuing his new claim, Mr. Iyilik relied on a specific article of the Turkish Civil Procedural Code which allowed for reopening of any civil proceedings if the impossibility to present certain pieces of evidence during the initial proceedings had constituted force majeure. The courts, however, rejected Mr. Iyilik’s request, relying on established jurisprudence of the Turkish Court of Cassation to the effect that the state of scientific progress could not reveal any force majeure.
