(a) Each appointing authority may appoint not more than two watchers for each precinct polling place, meeting place for an early voting ballot board, or central counting station involved in the election.

(b) Each appointing authority may appoint not more than seven watchers for each main or branch early voting polling place involved in the election. Not more than two watchers appointed by the same authority may be on duty at the same early voting polling place at the same time.

(c) In an election in which the election officers serving at a precinct polling place also serve as an early voting ballot board, a watcher who is appointed for the precinct polling place may observe the processing of early voting ballots by the early voting ballot board, or separate watchers may be appointed to observe only that activity.

If the number of appointments exceeds the authorized number, the authority accepting the watchers for service shall accept the watchers in the order in which they present their certificates of appointment.
