"Each entity subject to the provisions of this article, within five business days of the receipt of a written request for a record reasonably described, shall make such record available to the person requesting it, deny such request in writing or furnish a written acknowledgement of the receipt of such request and a statement of the approximate date, which shall be reasonable under the circumstances of the request, when such request will be granted or denied..."
"If circumstances prevent disclosure to the person requesting the record or records within twenty business days from the date of the acknowledgement of the receipt of the request, the agency shall state, in writing, both the reason for the inability to grant the request within twenty business days and a date certain within a reasonable period, depending on the circumstances, when the request will be granted in whole or in part."
"The determination of whether a period is reasonable must be made on a case by case basis taking into account the volume of documents requested, the time involved in locating the material, and the complexity of the issues involved in determining whether the materials fall within one of the exceptions to disclosure. Such a standard is consistent with some of the language in the opinions, submitted by petitioners in this case, of the Committee on Open Government, the agency charged with issuing advisory opinions on FOIL"(Linz v. The Police Department of the City of New York, Supreme Court, New York County, NYLJ, December 17, 2001).
"...any person denied access to a record may within thirty days appeal in writing such denial to the head, chief executive, or governing body, who shall within ten business days of the receipt of such appeal fully explain in writing to the person requesting the record the reasons for further denial, or provide access to the record sought."
