Louisiana Revised Statutes Tit. 18, § 427. Watchers

B. Powers and duties. A watcher shall be admitted within all parts of the polling place during the election day and the printing of results from the voting machines, and shall call any infraction of the law to the attention of the commissioners. A watcher may keep notes on the conduct of the election, but he shall not take part in the printing of results from the voting machines. A watcher shall not electioneer, engage in political discussions, or unnecessarily delay a voter at the polling place. A watcher shall be subject to the authority of the commissioners and shall not interfere with the commissioners in the performance of their duties.

C. Number of watchers inside a polling place. If the number of watchers inside a polling place is so great as to interfere with the orderly conduct of the election, the commissioners shall regulate the number of watchers inside the polling place for each precinct so that the election may be conducted in an orderly manner. The watchers shall draw lots under the supervision of the commissioners to determine which watchers shall be the first to wait outside the polling place, but the amount of time each watcher spends inside the polling place shall, as nearly as practicable, be equal.
