BIPM's official materials show that the vote was taken by the General Conference on Weights and Measures (CGPM), not by the BIPM itself.

• On BIPM's official page announcing the outcome, it says: "The 28th meeting of the General Conference on Weights and Measures (CGPM) adopted the following Resolutions on 15 October 2026." Resolution 5 is the one about ensuring the continuity of UTC.
• The text of Resolution 5 begins: "The General Conference on Weights and Measures (CGPM), at its 28th meeting ... decides that continuous UTC will become effective on 20 May 2027" and later "requests the BIPM" to carry out follow-up work. That structure makes clear the CGPM made the decision and the BIPM was tasked with implementing/supporting it.
• BIPM's own CGPM voting guidance also states: "Only Member States are empowered to take decisions and have voting rights at the CGPM."

So the post's wording is incorrect because it attributes the vote to the International Bureau of Weights and Measures (BIPM) rather than to the CGPM, the BIPM's plenary governing body made up of Member State representatives.
