The little used 10-year rule again (Section 19 of the FOI Act). This time the Cabinet agendas for Cabinet meeting for the first half of 2002. The documents outline what was on the agenda for meetings, including memoranda for government submitted, aide memoires, appointments, grants to industry and more. All of the listed documents are also likely obtainable in future FOIs.
Before the FOI Act these documents would generally only become available after 30 years, at the National Archives.
