R v Secretary of State for Foreign and Commonwealth Affairs, ex p Bancoult (No 1) [2000]

R v Secretary of State for Foreign and Commonwealth Affairs, ex parte Bancoult (No 1) [2000] EWHC Admin 413, commonly known as Bancoult (No 1) case, concerned a legal challenge brought by Olivier Bancoult who sought a judicial review of the ordinance facilitating the forced removal of the Chagossian people from their homeland. The case unfolded in 2000 before the Divisional Court.

Bancoult contested the legality of the ordinance, asserting that it was ultra vires, indicating that the power to legislate for the peace, order and good governance of the territory did not encompass the authority to expel its inhabitants.

The Divisional Court, after careful consideration, ruled in favour of Bancoult. The court held that the ordinance, which facilitated the Chagossian removal, exceeded the lawful powers conferred by the legislative framework. Specifically, the power to legislate for the territory's well-being did not extend to forcibly expelling its residents.

In response to the Divisional Court's decision, the ordinance was replaced by an Order in Council. This legislative action set the stage for subsequent legal developments in the case.

The legal journey continued in R v Secretary of State for Foreign and Commonwealth Affairs, ex p Bancoult (No 2) [2008] when the House of Lords, in a 3-2 judgment, upheld the legality of the Order in Council that replaced the contested ordinance.

Despite the Divisional Court's ruling in Bancoult's favour in the first instance, the House of Lords, by a narrow majority, determined that the replacement Order in Council was legal. The Lords' decision considered broader constitutional and geopolitical aspects, leading to a different outcome from the Divisional Court.

The legal saga of Bancoult (No 1 and No 2) highlighted the intersection of legal principles, executive powers, and geopolitical considerations. The case raised questions about the extent of government authority in legislating for territories, especially concerning the expulsion of inhabitants.

Bancoult (No 1) and its subsequent sequel, Bancoult (No 2), represent a legal odyssey where the Divisional Court initially found the ordinance ultra vires, only for the House of Lords to later uphold the replacement Order in Council. The case remains significant in discussions about the limits of executive authority and the legal intricacies surrounding the forced removal of the Chagossian people from their homeland.
