The planning commissioner and a real estate developer planned to meet to discuss rezoning certain land that would permit the real estate developer to construct certain buildings not allowed under the then-existing zoning law. A homeowners association claimed it had the right to be present at the meeting. This claim was objected to on the theory that the state's Open Meetings Act applied only to meetings of specified government units and did not extend to a meeting between one of them and an outsider. Was this objection valid?

what law has been triggered by this question?
