In its report, the auditor said that when the Airport Metro link was envisaged it was agreed that DIAL would pay upfront Rs 350 crore for civil work for the line inside the airport. An Empowered Group of Ministers (EGoM) had approved this plan, the report said.
DIAL then asked DMRC to build a station near National Highway-8 to serve its commercial areas for which it promised an additional Rs 98 crore to be paid in advance. Commercial rights of NH-8 and airport metro stations were given to DIAL.
The report said that DMRC had eased the conditions on a request by secretary of the civil aviation.
The CAG also said that while the four instalments had to be paid on the first day of June 2009, September 2009, December 2009 and March 2010, DIAL did not make the payments as per the agreed schedule and an amount of Rs 54.43 crore was still outstanding as on February, 2013.
The CAG report has also found fault with the DMRC for having written a recommendation letter to the customs department which enabled, the Airport metro line operator - Delhi Airport Metro Express Private limited (DAMEPL) to get a benefit of Rs 29.56 crore.
