Article 8 of the European Convention on Human Rights provides a right to respect for one's "private and family life, his home and his correspondence", subject to certain restrictions that are "in accordance with law" and "necessary in a democratic society". The European Convention on Human Rights (ECHR) (formally the Convention for the Protection of Human Rights and Fundamental Freedoms) is an international treaty to protect human rights and fundamental freedoms in Europe. Right Article 8 is considered to be one of the convention's most open-ended provisions. Family life In X, Y, and Z v. UK, the Court recalls that "the notion of 'family life' in Article 8 is not confined solely to families based on marriage and may encompass other de facto relationships.

This may be compared to the jurisprudence of the United States Supreme Court, which has also adopted a somewhat broad interpretation of the right to privacy. Furthermore, Article 8 sometimes comprises positive obligations: whereas classical human rights are formulated as prohibiting a State from interfering with rights, and thus not
