1918, however, Louise's father explained to her that Stuart-Hill was most likely homosexual, and that a marriage with him was impossible. In 1923, Crown Prince Gustaf Adolf of Sweden, having been for three years the widower of Louise's mother's cousin Princess Margaret of Connaught, paid a visit to London and, to Louise's surprise, began to court her. Although as a young woman Louise had said that she would never marry a king or a widower, she accepted the proposal of a man destined to be both. However, under §5 of the 1810 Swedish Succession Law (Act 1810:0926), a prince of the Swedish royal house forfeited his right of succession to the throne if he "with or without the King's knowledge and consent, married a private Swedish or foreign man's daughter" (med eller utan Konungens vetskap och samtycke, tager till gemål enskild svensk eller utländsk mans dotter). Once the couple's engagement was announced, there were lively discussions in the media about whether the bride-to-be was constitutionally eligible to become Sweden's future queen. In response, the Swedish Foreign Ministry, citing the law in question, clarified the term "a private Swedish or foreign man's daughter" to mean "he who did not belong to a sovereign family or to a family which, according to international practice, would be equal thereto" (som icke vore medlem av suverän familj eller familj som enligt internationell praxis vore därmed likställd), and announced that the Swedish government had "requested the British government's explanation of Lady Louise Mountbatten's position in this respect." The ministry further announced that following the British government's reply to its inquiry and the subsequent investigation into the matter, it had been determined that the Crown Prince's choice of a future wife was in compliance with the succession law, thereby concluding debate on the imminent nuptials. On 27 October 1923, Sweden and Britain's respective plenipotentiaries signed the "Treaty between Great Britain and Sweden for the Marriage of Lady Louise Mountbatten with His Royal Highness Prince Gustaf Adolf, Crown Prince of Sweden". The treaty stated, in part, that the kings of the United Kingdom and Sweden "having judged it proper that an alliance should again be contracted between their respective Royal Houses by a marriage...have agreed upon and concluded the following Articles", which articles declared that the marriage would be celebrated in London and duly authenticated, that the couple's financial settlements would be expressed in a separate marriage
