R (on the Application of Safe Passage International) v Secretary of State for the Home Department

This title refers to a judicial review case heard in the courts of England and Wales. In legal terminology, "R" stands for "Regina" (if the reigning monarch is Queen) or "Rex" (if the reigning monarch is King), and it represents the Crown as the nominal prosecutor in criminal cases or a party in public law matters. "on the Application of" indicates that a specific individual or organization, in this case, "Safe Passage International," initiated the legal proceedings. "v" stands for "versus" and denotes the opposing party, which in this instance is "Secretary of State for the Home Department," a senior government minister responsible for immigration, security, and law and order in the United Kingdom.

Therefore, the full title signifies a judicial review brought by Safe Passage International against the UK Home Secretary, likely challenging a decision or policy of the Home Office through the legal process of judicial review. The case would have involved legal arguments concerning the lawfulness of the Home Secretary's actions or policies, judged against principles of administrative law. Safe Passage International is a non-governmental organization advocating for safe and legal routes for refugees to reach safety. The precise subject matter of the legal challenge would be determined by the specific facts and arguments presented in the case.
