§ 9-900 Acts or resolutions of the board of trustees that are subject to referendum on petition. l. Whenever this chapter shall expressly provide that an act or resolution of the board of trustees is subject to a permissive referendum, such act or resolution shall be subject to a referendum on petition as set forth in the next section.

2. Within ten days after the performance of any act or the adoption of any resolution by the board of trustees which is subject to a permissive referendum as above described, the village clerk shall, in the same manner as is provided for notice of a general village election, post and publish a notice which shall set forth the date of the adoption of the act or resolution and contain an abstract of such act or resolution concisely stating the purpose and effect thereof, and indicating that such act or resolution is subject to a permissive referendum.

3. Whenever any state statute shall provide that any local law or resolution of the board of trustees is subject to a mandatory referendum and if no other procedure is otherwise provided for, such referendum shall be conducted as provided in this article as if such referendum were a permissive referendum upon which a valid petition had been filed with the date of adoption of such act or resolution by the board of trustees being deemed the date of the filing of the petition. In the event a mandatory referendum on the adoption of a local law is held at a time other than at the time of a general village election for officers as provided by section twenty-three of the municipal home rule law, such referendum shall be conducted as provided in this article as if such referendum were a permissive referendum upon which a valid petition had been filed with the date of the adoption of such local law by the board of trustees being deemed the date of the filing of the petition.
