This article from The (Tacoma) News-Tribune discusses the Port of Olympia's apparent belief that they can discuss things like the creation of a new position at a "study session."
If the "study sessions" are not properly noticed regular or special meetings, the Port cannot discuss Port business, and the creation of a new Port position certainly qualifies as that. If the meetings are a properly noticed special meeting, and there is no indication in the story that they are, then they can only discuss the items on the agenda for that special meeting, not drift into new areas.
