Yes, a request for a record can be refused if the record or part of the record falls within one of the exemptions or if the request is deemed to be frivolous or vexatious. Once the decision to refuse access to the record, in whole or in part, has been made, written notice of the decision (a “decision letter”) must be provided to the requester and any affected third-parties. The decision letter must be provided to the requester within the 30-day time period (or within the period of extended time, if any).
