§ 5.5. Restrictions of power of the council.

The council shall not have the power to make any contract with or give any official position to any person who is in default to the city. Except in the course of an investigation, neither the council, nor any of its committees shall deal directly with any appointive administrative officer or department of the city, but shall conduct its affairs with such officers and departments through the mayor. Further, the council shall not have the power to sell any park, cemetery, or any part thereof, except where such park is not required under an official master plan of the city, or any property bordering on a water front, or to engage in any business enterprise requiring an investment of money in excess of ten cents per capita, unless approved by three-fifths of the electors of the city, voting thereon at any general or special election.
