I will be very quick, given the time before the vote.
The document, to my knowledge, was not requested through an order for the production of documents. It was requested for further information or as a question taken as notice. Documents tendered to the committee are the possession of the committee. The committee can do with them as it wishes during the sitting. At the end of the sitting, all of the documents, unless they have been deemed by the committee to be confidential, are made public, and they are available to be searched.
If the committee wishes to discretionally not release the document at this point but have it be public only at the end of the sitting, that is certainly within its rights. If the committee wants to render it public at any point, it can. It can choose to publish it on the website, or it can choose to designate it as confidential.
All of these are options for the committee to consider.
