Facts to gather first
- Whether the redacted or withheld information identifies an individual or a business/entity.
- Which specific identifiers were redacted or withheld (e.g., home address, personal phone, business phone, name, middle initial, date of birth, full or partial license plate).
- What the record is and whether it involves public funds, assessments, police reports, or witness statements.
- Whether the public body cited only section 7(1)(b) and whether it explained who the redaction protects.
These letters are non-binding, outcomes depend on the specific facts and how the public body justifies each redaction, and you should verify the underlying PDFs before relying on them.
