When Power Goes Wrong · Evidence & Proof Ledger · Part 28

How far can the Official Information Act take you before litigation?

The OIA can obtain official information, internal decision rules and reasons for decisions, making it a powerful pre-litigation evidence tool. But withholding grounds, privacy, privilege and scope limits remain, and disclosure does not automatically make a document admissible at trial.

The Official Information Act 1982 is often the first evidence-gathering route available before proceedings are filed.

Section 5 establishes the principle of availability, subject to statutory withholding grounds. Section 22 provides access to internal rules affecting decisions. Section 23 gives a person a right to reasons for a decision affecting that person. Sections 12–19 govern ordinary requests, forms of release, refusal and reasons for refusal.

Use the OIA to identify the decision chain.Ask for the decision, briefing, delegated authority, chronology, meeting records, policies, internal rules, relevant correspondence and the identity/role of decision-makers. Broad fishing requests are less effective than issue-specific requests tied to a date, decision and legal power.

Can revealBriefings, policies, internal rules, reasons, emails, reports, chronologies and delegations where not lawfully withheld.

Can be withheldMaterial protected by statutory withholding grounds, including legal professional privilege where applicable.

Review routeOmbudsman review of refusal/withholding decisions.

Trial warningObtaining a document under OIA does not itself establish authenticity, truth of every statement, or admissibility.

The best OIA request is built from the elements of the future claim, not from curiosity alone.

Primary statuteOfficial Information Act 1982, especially ss 5, 12–19 and 22–23.
