The issue whether a commitment made by a Minister on the floor of the House has been fulfilled or not is decided by the :

The Committee on Public Assurances (also known as the Committee on Government Assurances) is specifically tasked with examining the assurances, promises, and undertakings given by Ministers on the floor of the House [2]. Its primary function is to report on the extent to which these commitments have been fulfilled or carried through by the executive [4]. Constituted in 1953, the committee acts as a parliamentary watchdog to ensure executive accountability [4]. In the Lok Sabha, it consists of 15 members, while the Rajya Sabha committee consists of 10 members [2]. While the Ministry of Parliamentary Affairs tracks these assurances internally, the formal parliamentary decision and reporting on their fulfillment rest with this specific committee [4]. Other committees like the Business Advisory Committee or Departmentally Related Standing Committees focus on legislative timetables and budgetary scrutiny respectively [3].
