Under the leadership of Murray Seasongood, the Charter Committee proposed the country's first  Council-Manager form of local government. The new charter replaced political patronage with civil service, implemented proportional representation, and established several separate Boards and Commissions, such as the Health Department, Parks, Historic Preservation and others. The first charter election resulted in six of nine council members from the Charter Party. Murray Seasongood was selected Mayor.

​

The Charter Committee has continued to be an active and important presence in Cincinnati for many decades. Charterites who have served as Mayor include: Dot Dolbey, Cincinnati's first woman mayor, Theodore Berry, Bobbie Sterne and Tom Brush. Other Charter council members include Arn Bortz, Marian Spencer, Jim Tarbell, Reggie Williams, Roxanne Qualls, Christopher Smitherman, Kevin Flynn and Yvette Simpson.

​

In 1999, voters amended the Charter, Cincinnati's constitution, to strengthen the Mayor's position. The Mayor became separately elected and was given the right to control Council's agenda, appoint members to Boards and Commissions, control committee agendas, initiate the hiring and firing of the City Manager, and veto  Council votes. In 2013 the Charter was again amended to give the Mayor and Council four year terms. This amendment was rescinded in 2019 to return to two-year terms for Council members. The 2021 election elected a Mayor for a four year term and all Council members for two year terms.​

​

In 2022 there were 2 changes, both at least partly the result of work by the Charter Committee. The City voted to eliminate the 'Pocket veto', a loophole that had been used multiple times since the 'Strong Mayor' vote. The Pocket Veto was used by Mayors to kill legislation by excluding topics from Council Meetings. The mayor and committees now have a maximum time they can delay items before items automatically appear on the appropriate agenda.

​

City Council also began the use of 'executive sessions', allowing discussion of sensitive topics without the public having access, but only in stricty controlled circumstances.
