Quorum not met so the question was not decided and the debate adjourned in accordance with Standing Order 56
If, on a division upon a bill, or upon a Question for the approving or disapproving of secondary legislation, less than thirty Lords have voted, the Lord Speaker shall declare the Question not decided, and the debate thereon shall stand adjourned to a subsequent sitting.
Librarians actualise this step alongside the question being put. We'd expect to see the question step actualised again, usually, the following day when the debate resumes briefly.
