Sources said the committee consisting of Additional Secretary D Diptivilasa and then Additional Member (Works) in the Railway Board A K Gupta presented its findings in a 103- page report along with 119 pages of annexures to Urban Development Secretary Sudhir Krishna from where it has been sent to Urban Development Minister Kamal Nath's office.
Sources said the committee has found certain lapses on the part of different stakeholders including officials of the Delhi Metro Rail Corporation (DMRC), a consultant and one of the contractors associated with the project besides the concessionaire which was operating the line.
The Delhi Airport Metro Private Limited had to stop operations of the line on July 8, 2012 following serous defects which could even have endangered passenger safety.
The operations on the line resumed earlier this year after prolonged closure due to repair work.
