In a municipal corporation the Mayor is the elected head; in a municipality the Chairperson has the corresponding political role. A municipal Commissioner is the chief executive or administrative officer under the applicable law and delegations. The elected body debates policy, approves decisions within its powers and represents residents; officials prepare estimates, administer staff, collect revenue and execute sanctioned works. Exact duties vary by statute and delegation, so avoid an absolute claim that one officer personally controls every service.

The distinction is useful when interpreting public complaints. If waste is not collected, the ward representative can raise the issue; the sanitation chain must establish route, staffing, vehicle and contractor evidence. If a municipal budget is disputed, inspect council proceedings, approved budget and accounts. The AP CDMA portal describes its state-level supervision of urban local bodies and its election-related role under the State Election Commission. CDMA is a directorate, not a replacement for a city's elected corporation.

Worked example: A Mayor announces a road repair but the municipal commissioner controls execution under the applicable administrative arrangement. Elected leadership, council decisions and executive administration interact but are not identical offices. A complaint about a contractor's measurement may belong to the engineering and accounts chain. A political statement is not a work order or completion certificate.

Active recall: Compare the elected and executive sides of a corporation. Where would you look for proof that a council adopted a resolution?
