How to review your police disclosure or discovery — page by page

A practical guide for defendants who want to read their own file before their next lawyer meeting. What every section means, what to flag, and the questions to ask.

What's in a typical disclosure file

Whether your file is called disclosure (Canada) or discovery (USA), the contents are similar:

• Officer notes — the handwritten or typed notes each officer made during and after your encounter
• Police report / occurrence report — the formal narrative summary
• Witness statements — anyone the police interviewed
• Body-worn camera & dashcam footage — video and audio of the stop, arrest, search, and transport
• Breath sample certificates (DUI/impaired) — Intoxilyzer or Datamaster results, calibration logs
• Search warrants & supporting affidavits — the document that authorized any search of your home, vehicle, or phone
• Chain-of-custody logs — who handled physical evidence and when
• Lab and forensic reports — toxicology, fingerprints, DNA
• Photographs — scene photos, evidence photos, booking photos
• 911 call audio & dispatch logs
• Exculpatory material — anything that helps you (Brady in the US, Stinchcombe in Canada)

Officer notes — the most important pages

Officer notes are usually the source of every Charter or Constitutional issue you'll find. Read them with a pen and a timeline.

What to flag:

• Timing of every event. Stop, arrest, caution given, right to counsel given, breath demand, transport to station, breath sample. Each one should have a time. A 17-minute gap between arrest and being told you can call a lawyer can be a Section 10(b) issue (Canada) or Miranda issue (US).
• Exact words used. "I told the suspect of his right to counsel" is not the same as documenting the actual words. Vague language often means the officer didn't follow the script.
• Inconsistencies between officers. Two officers' notes about the same event should match. When they don't, you have credibility ammunition.
• When the notes were made. Notes written "later that shift" or "the next day" are weaker than notes made contemporaneously. Look for the "completed at" timestamp.
• Inserted text or odd formatting. Lines squeezed in, different ink, page numbers that skip, scratched-out passages — all worth flagging.

Body-cam and dashcam — the smoking gun

Body-worn camera footage often contradicts officer reports. Watch the entire footage even if it's hours long. Pay attention to:

• Whether you were told about your right to a lawyer at all
• Whether the officer asked questions before reading you your rights
• Whether you were given a real opportunity to make the call (a phone, a private space)
• Whether the officer's conduct matches what's described in the written report
• Pre-arrest detention duration ("I just held him for the dog")

Breath certificates (DUI / impaired driving)

In impaired driving cases, the breath certificate is everything. Look for:

• Calibration logs — when was the machine last calibrated? By whom? With what standard?
• 15-minute observation period — required between samples in Canada; some US states have similar protocols
• Time of the breath demand vs. time of the sample — Canadian law requires "as soon as practicable"
• Whether you were given right to counsel before the sample
• Whether the qualified technician was actually qualified on that specific machine

Search warrants — read the affidavit

If your case involves a search of your home, vehicle, or phone, ask your lawyer for the Information to Obtain (ITO) in Canada or the warrant affidavit in the US. This is the document the officer swore to convince a judge to issue the warrant.

It must establish reasonable grounds (Canada) or probable cause (US) based on facts, not hunches. Watch for: vague allegations, "an anonymous tip" with no corroboration, statements made by an officer with personal motive, or omission of facts that would have hurt the case for a warrant. Defective ITOs can lead to evidence exclusion.

Timeline tracking — Jordan / speedy trial

Write down: date of charge → date of every court appearance → trial date. In Canada, R v. Jordan sets presumptive ceilings (18/30 months). In the US, the Speedy Trial Act (federal) and Barker v. Wingo (state) govern delay. If your trial is being scheduled past those limits, raise it with your lawyer.

Skip RightsRadar — but only if you have time

If you have 4–8 hours to read a 150-page file with care, you can do this yourself. Most people don't. Most public defenders don't either — they're carrying 100+ active files.

RightsRadar is built for the people in the middle: people who want a structured, AI-generated review of their file in 60 seconds, with specific issues flagged and questions to ask their lawyer. $29.99. Not legal advice. Just an issue-spotter that does what an over-stretched lawyer doesn't have time to do.
