WIC §4661: (a) Regional centers shall mail notice of their meetings to any person who requests notice in writing.

(a) Regional centers shall mail notice of their meetings to any person who requests notice in writing. Notice shall be mailed at least seven days in advance of each meeting. The notice shall include the date, time, and location of, and a specific agenda for, the meeting, which shall include an identification of all substantive topic areas to be discussed, and no item shall be added to the agenda subsequent to the provision of this notice. The notice requirement shall not preclude the regional center board from taking action on any urgent request made by the department, not related to purchase of service reductions, for which the board makes a specific finding that notice could not have been provided at least seven days before the meeting, or on new items brought before the board at meetings by members of the public. (b) The regional center shall maintain all recordings and written comments submitted as testimony on agenda items for no less than two years. These materials shall be made available for review by any person, upon request. (c) Any action taken by a board that is found by a court of competent jurisdiction to have substantially violated any provision of this article shall be deemed null and void.
