Unlike a Select Committee, the ISC shares its reports with the Government and Agencies it oversees in advance of publication. This is to ensure that no details which might damage national security are published. Each report is subject to four stages: requests for factual amendments; requests for redactions; contested requests for redactions (where the Committee is unwilling to accept an initial redaction request, representatives of the Agencies must appear to argue the case); and confirmation from the Prime Minister that the document no longer contains any details damaging to national security. By convention, the Prime Minister has 10 working days in which to examine the report and confirm that there are no national security issues outstanding. Once that certification is received the Committee makes administrative arrangement to lay the Report before Parliament.
