In 1875, the city of Chicago adopted the Cities and Villages Act of 1872, which called for municipal elections to be held in April, instead of November. Harvey Doolittle Colvin, the current mayor, was informed by his attorneys that his term should be considered extended to the new elections. While the charter did not explicitly extend his term, it also failed to include the office of mayor in a call for special elections to fill the period from November to May.
