If a city is divided into several wards and the councilmen are elected only by their wards, a primary election is necessary in wards where two or less candidates have filed for a council seat if even a single office has more than two persons filed for it. That portion of a 1st class city charter is void which provides that under certain circumstances a candidate may be elected to an office at a primary election. However, a 1st class city charter may provide that a candidate receiving a majority of the primary votes for an office shall alone appear on the general ballot.
In the event a county clerk elected for a term expiring January 1, 1958, dies on August 29, 1956, which date is subsequent to the last day for filing for the September primary, but several candidates for the unexpired term of county clerk run as "sticker candidates", the candidates to represent the respective political parties in the general election may be nominated in the primary by stickers, provided that the specified percentage of votes is cast for them; otherwise, nomination is made by the county central committees for the respective parties. Special notice is required in the general and primary election held to fill the unexpired term of a superior court clerk.
