Maltese authorities denied Maltese nationality to a child on the basis that they were born out of wedlock to a Maltese father and a British mother. Domestic legislation only conferred nationality to children born out of wedlock if the mother was Maltese. The Court rejected the argument advanced by the Maltese Government that this case was justified on the basis that a mother is always certain, whereas a father is not. It concluded that no reasonable grounds were adduced to justify such a difference in the treatment of the applicant and found a violation of Article 14 in conjunction with Article 8 ECHR.
The applicant was born in the US, and his birth certificate indicated a Polish national as the father, and an unknown surrogate mother as the mother. Polish authorities refused to confirm the applicant acquired Polish nationality at birth as a child of a Polish parent, because the birth certificate is against the Polish public order, in particular the prohibition of surrogacy. The courts ruled in favour of the applicant, stating that confirmation of his Polish nationality on the basis of the birth certificate does not amount to validation of surrogacy.
