The Line I of the Mumbai Metro was being built by REL, Veolia Transport and MMRDA through the SPV, MMOPL. The project had been initiated by the Maharashtra State Government through the MMRDA. Due to the amendments in the Metro Railways Act, the project came under the Centre, after award of the concession. The amended MRA gave the initial fare fixation right to MMOPL, to be followed by reviews by an FFC. MMOPL proposed a fare structure higher than what MMRDA had proposed as per the CA, justifying it on increased project costs on account of delays in construction. This was unacceptable to MMRDA. After a series of court hearings, an FFC was formed to review the fares.
