I have been attending the first two sessions of the Public Bill Committee on the Education and Adoption Bill. The afternoon hearing shuddered to a sudden halt, when it was realised that the witnesses' microphones weren't working. We had to wait until the correct button was hit before the 20 person committee and the 3 witnesses could start.
It was explained that without the microphones, there was nothing for Hansard to use in preparing a transcript. Without that record, legally the evidence did not exist - hence the delay. A number of suggestions were made about getting the witnesses to be heard, but that was not the issue.
