Key Findings

1995 advice letters tracked — covering ministers, special advisers, and senior civil servants taking private sector roles after leaving government.
941 minister applications — former ministers must seek ACOBA advice before taking any role in their first two years after leaving office.
1991 cases had conditions — including lobbying bans, waiting periods, and restrictions on using privileged information from their government role.
ACOBA advice is non-binding — the committee can recommend but not prohibit. Compliance is voluntary, which limits the mechanism's enforcement power.
