Your response is confused.
#1 a city is a municipality, as are towns, villages and in Connecticut three Boros.
#2 Cities cannot vote, people vote
#3 Municipalities can determine subject to individual State laws and Constitution who may vote and requirements to serve on Municipal Commissions, Boards and Committees.
a. I cited municipalities in CT as examples. Only registered voters may vote to elect people to municipal government. Many towns have a requirement that the Town budget be approved by a referendum, not the only the Town Council. Some towns open these budet votes to all taxpayers, not just registered voters of the town. For example: I own an industrial building in the town next to where I live and am registered to vote. I pay more than 100K in yearly property tax. I have a vested interest in that town’s budget. I am permitted as a taxpayer to vote in the Tax Referendum and have done so for 20 years.
b. One must be a registered voter to be elected Mayor, First Selectman, Council Member, Board of Finance, Board of Education and many other municipal boards, committees and commissions. My town requires anyone appointed to a Town Committee, Board or Commission (I chair the Economic Development Commission) must be a registered voter and appointment approved by the Town Council. Our Charter sets limits on how many members from each party may serve on a commission to keep things balanced.
c. Constituent Agencies such as the Board of Education can establish committees and set parameters for membership as long as in compliance with State law. I explained that the Schools Athletic Committee includes high school students too young to vote.
d. Library Boards in Connecticut are actually State Chartered, not municipal (keeps local politicians from raiding library trust funds) and members need only be residents, not voters nor citizens.
San Francisco dropped (In compliance with California law) a citizenship requirement for service on NON-legislative committees, authorities and Boards. These groups cannot make laws, levy taxes, etc.
I would not be opposed to a non-citizen serving on my municipal Parks commission if he/she had a passion and some valuable contribution to make, The commission is an advisory group to the Parks and Recreation Department. It doesn’t determine budget or spending, hire or fire employees, stc.
Hope this makes it clearer.
The commission the non Citizen was appointed to in San Francisco does NOT make election law or determine who may vote. It helps select polling places, distributes voter education materials, helps spread the word that poll workers are needed, but does not hire or train them.
