Under the Public Information Act, some categories of records are not required to be released. Exceptions to disclosure fall into two general categories:
1) mandatory exceptions that make information confidential and require a governmental body to withhold records, and 2) discretionary exceptions that allow but do not require a governmental body to withhold records.
You may find information about mandatory and discretionary exceptions at:

In most instances, a governmental body is required to request a decision from the Attorney General in order to withhold records from a requestor. However, there is some information that may be withheld without requesting a decision from the AG (e.g., social security numbers).
Additionally, in other instances, a requestor may permit a governmental body to redact records without requesting an Attorney General decision. You are not required to agree to the redaction of any records responsive to your request, but doing so may streamline the handling of your request. If you agree to redactions in this request, then you may request the redacted records in a future records request.
