Freedom of information exemptions

There are two types of exemption Absolute and Qualified. Those exemptions defined as Absolute do not require a Public Interest Test.

Absolute Exemptions

Where an absolute exemption applies, there is no right to the information under the Freedom of Information Act 2000.

Section 21 - Information Accessible by Other Means.
Section 23 - Information Supplied by, or Related to, Bodies Dealing with Security Matters.
Section 32 - Court Records.
Section 34 - Parliamentary Privilege.
Section 36 - Prejudice to Effective Conduct of Public Affairs.
Section 40 - Personal Information.
Section 41 - Information Provided in Confidence.
Section 44 - Prohibitions on Disclosure.

Qualified Exemptions

Section 22 - Information intended for future publication.
Section 24 - National Security.
Section 26 - Defence.
Section 27 - International Relations.
Section 28 - Relations within the United Kingdom.
Section 29 - The Economy.
Section 30 - Investigations and Proceedings Conducted By Public Authorities.
Section 31 - Law Enforcement.
Section 33 - Audit Functions.
Section 35 - Formulation of Government policy.
Section 36 - Prejudice to the effective conduct of public affairs.
Section 37 - Communications with Her Majesty.
Section 38 - Health and Safety.
Section 39 - Environmental Information.
