Building a Disclosure Contradiction Schedule
How to compare records from different sources and capture inconsistent dates, statements and decision rationales.
Updated September 2026
The useful starting point is not the volume of paperwork. It is the decision or issue, the evidence relevant to it, the chronology and the next decision-making stage.
Auditing disclosure and information rights
Keep the original request, proof of scope and every response or disclosure tranche.
Index the material by source and date so missing periods, redactions and contradictions become visible.
Separate suspected missing material from records you can positively show should exist.
1. Identify exactly what is being challenged
Keep the original decision, order, report, notice or correspondence. Record its date, the decision-maker, the reasons given, every relevant deadline and the precise outcome you want. A difficult matter becomes easier to analyse when the disputed questions can be stated concisely.
2. Build an evidence-linked chronology
Create a dated sequence of material events and link each important event to its source document. The chronology is a navigation tool: a reader should be able to understand what happened, when it happened and where the supporting evidence can be found.
3. Separate evidence, allegation and inference
Mark what is proved by a contemporaneous record, what is alleged by a person or organisation and what is an inference, opinion or disputed conclusion. Then identify contradictory records, missing material and conclusions for which the supporting evidence is unclear.
4. Check the current framework
Identify the legislation, procedural rules, statutory guidance and published policy that actually apply to the particular decision. Use current authoritative material. A strong challenge connects the evidence to the applicable framework and the outcome sought.
5. Prepare for the next decision point
Work backwards from the next hearing, review, committee, complaint stage or decision. Identify what must be provided, what the decision-maker needs to understand and which documents best demonstrate each important point.
Information-rights routes differ between SAR, FOI and other disclosure regimes. Sensitive third-party information must be handled carefully.
Questions to ask before proceeding
What is the exact decision? What deadline applies? Which facts are genuinely disputed? What documents prove the important facts? What framework governs the decision? What outcome are you asking for? What has already been tried? Those questions expose the gaps that need work.
