22 A House of Commons briefing paper notes that “there is a broad consensus among commentators that the ruling puts greater international legal pressure on the UK government” (Claire Mills, Disputes Over the British Indian Ocean Territory: February 2021 Update, House of Commons briefing paper, No 9134 (Feb. 8, 2021), https://researchbriefings.files.parliament.uk/documents/CBP-9134/CBP-9134.pdf.
