§ 146. Approval of comptroller. The comptroller shall not approve or file any procurement contract for the acquisition of goods or services in the amount of fifty thousand dollars or more unless notice as provided in section one hundred forty-two of this article shall first have been published in the procurement opportunities newsletter at least fifteen business days prior to the date on which a bid or proposal was due. Provided, however, such requirement of publication of advance notice shall not apply to contracts exempt from such requirement under section one hundred forty-four of this article; provided further, that the comptroller shall not be required to disapprove a contract if he or she determines that there has been substantial compliance with the requirements of section one hundred forty-two and section one hundred forty-three of this article. The foregoing provisions of this section shall not be construed to limit, in any manner, the right of the comptroller to demand evidence of adequate competition or such other proofs as he or she may require in the discharge of his or her responsibilities pursuant to § 112 of the state finance law or any other provision of law.
