The Joint Commission on Public Ethics accused Mr. Cuomo of essentially obtaining approval under false pretenses, including breaking his promise not to use state resources toward completion of the memoir.

“Contrary to the representations made on behalf of Governor Cuomo and not disclosed to the commission, state property, resources and personnel, including staff volunteers, were used in connection with the preparation, writing, editing and publication of the book,” according to a resolution that was approved by a 12-to-1 vote.

The commission also noted several misrepresentations in Mr. Cuomo’s request for the ethics commission’s approval, including the nature of the book’s subject matter and how far along the project was at the time of the request. It also noted that the full financial details of the deal and contract had been withheld from the panel.
