OPINION OF THE COURT
The 1988 to 1991 collective bargaining agreement between petitioner and the State included a performance advancement increment which provided that after employees had worked 100 days in the fiscal year and achieved a satisfactory job rating, a percentage increase in salary would be paid commencing after the succeeding April 1st date. The contract also included a longevity increment schedule which added percentages to the base wages of employees on the 10th, 15th and 20th anniversary of employment, which like the performance advancement increment commenced at a future payroll date.
Petitioner commenced this CPLR article 78 proceeding to annul the determination on the grounds that it was arbitrary and capricious, affected by an error of law and not supported by substantial evidence on the record. An order was then entered transferring the proceeding to this Court.
Petitioner argues that PERB’s determination is arbitrary and capricious because PERB failed to either conform to its own precedents or established policies, or to explain a departure therefrom. In Matter of Field Delivery Serv. (Roberts) (66 NY2d 516, 516-517), the Court of Appeals held that "[a] decision of an administrative agency which neither adheres to its own prior precedent nor indicates its reason for reaching a different result on essentially the same facts is arbitrary and capricious” (emphasis supplied). The Court adhered to this principle in Matter of Lafayette Stor. & Moving Corp. (Hartnett) and Matter of Lincoln Stor. (Hartnett) (77 NY2d 823) and Matter of Martin (Troy Publ. Co.—Roberts) (70 NY2d 679). Petitioner contends that in the past, inaction by an employer to a request for information from an employee organization
The rule of law limiting the departure from administrative precedent relied upon by petitioner (Matter of Field Delivery Serv. [Roberts], supra) requires the facts of the instant case to be essentially the same as those in the precedent. Here, the administrative determinations relied upon by petitioner do not contain essentially similar facts.* Moreover, the record shows that the State properly responded to petitioner’s inquiry. By lodging an information request petitioner sought to expand the State’s obligation to provide documents and objective data. In essence, petitioner sought to compel the State to develop information not yet in existence and then to disclose that information. PERB correctly held that petitioner had not been wrongfully denied information to which it was otherwise entitled.
Petitioner additionally contends that PERB’s determination that insufficient evidence existed to establish the charge that the State had violated Civil Service Law § 209-a (1) (a) and (d) is not itself supported by substantial evidence. A review of the record, however, reveals, at best, only a weak development of petitioner’s allegations made by individuals who lacked direct knowledge of the pertinent facts. Bare surmise, conjecture, speculation and rumor are insufficient to establish a basis for an administrative determination (300 Gramatan Ave. Assocs. v State Div. of Human Rights, 45
We find PERB’s conclusion to be fully and rationally supported by the record; its determination is therefore confirmed.
Mikoll, J. P., Mercure, Crew III and Yesawich Jr., JJ., concur.
Adjudged that the determination is confirmed, without costs, and petition dismissed.
