All public bodies are obliged to publish Section 15 and Section 16 reference books every three years under the FOI Act. The Department of Justice website says:
The reference books are available for inspection in public libraries, Garda stations, court offices and all offices of the Department.
Great. No sign of the actual reference book though.
So I now give you: the Department of Justice reference book, available exclusively on thestory.ie, after some deep searching on Google. It makes for very very interesting reading. After reading through it, you might see why the document was deliberately not placed on the Department of Justice website. I should say I have used this reference book for at least two FOI requests that I have yet to write about.
