Do meetings of committees, for example Executive, By-Laws, and Filming Committees, have to be open to the public (difference between standing and ad hoc committees)?
Yes, assuming Neighborhood Councils established subcommittees, and only members of the Neighborhood Council serve on these subcommittees. The Brown Act provides that meetings of standing committees (those that have on-going jurisdiction of a particular subject matter) are subject to the provisions of the Act. However, temporary, ad-hoc committee meetings are not subject to the provisions of the Brown Act, so long as the members of that committee do not constitute a majority of the governing body of the Neighborhood Council.
