Step-by-step explanation:
The final word on whether county boundaries may be changed rests with the government entities that have jurisdiction over the specific county involved. In the United States, county boundaries are typically determined and regulated by state governments. The state legislature or a state agency responsible for boundary changes, such as a county commission or board, ultimately makes the decision.
For example, in the state of California, county boundaries can be changed through legislation passed by the California State Legislature. In other states, boundary changes may be handled by a specific county government body, such as a county board of supervisors. The process typically involves public input and may require approval from multiple levels of government.
