Dover residents will go to the polls June 17 to elect a new mayor.

Dover City Council on Monday night voted to set Tuesday, June 17, as the date for elections to select a new mayor for the city of Dover.

The special election is needed due to the resignation of Mayor Carleton E. Carey Sr., who stepped down effective at 8 a.m. April 28.

Council also set April 29 through May 20 as the dates prospective candidates may file election petitions, and said voter registration will close on June 3.

The soonest a new mayor may be sworn in is Wednesday, June 25.

A special election is required whenever a vacancy occurs in the mayor’s office or among City Council members when more than six months remains until the expiration of the office holder’s term.

Carey’s term was to expire in May 2015; whoever is elected will serve until that time, and would be eligible to run for re-election to the post.

In the event a sitting City Council member is elected mayor, a special election would be needed to fill that individual’s seat.

Speaking at the April 28 session of Dover City Council, Councilman James L. Hutchison Sr. said prospective candidates should be aware council plans to vote on changes to the mayor’s office.

Hutchison, who is a retired Dover police chief and who served as mayor himself for 10 years, said those changes most likely will come before a new chief executive is selected.

Council’s next meeting is Monday, May 12.

“One of the things this council will be doing on May 12 is looking at the duties and responsibilities of the police department,” Hutchison said. The mayor currently oversees the police department, and selects the new chief of police.

Those responsibilities could be moved under the city manager, if a proposed ordinance is approved.

Council was to consider that legislation on Monday, but postponed discussion due to Carey’s departure.
