Same co. one is a state autonomous another is not.

As per the central govt. Memorandum the service is counting for pension purpose if the employee transfers from state govt. To central govt. Or their autonomous bodies. As per this rule the service of state govt employees of maharashtra is counting in pune corporation but mumbai corporation rejected my application so, I am surprised how it is possible that one corporation is state autonomous body & another is not. So please guide me. If possible give the documents showing municipal corporations are state autonomous bodies. I am ready to pay legal charges for this documents.
