 no. TO/03/2012 dated 9th April 2012 determined the per unit network
 tariff and compression charge for the CGD Network of IGL for Delhi,
 based on submission of data by the company in May 2009 and certain
 assumptions taken by PNGRB in this regard. The tariffs determined by
 PNGRB are much lower than the rates submitted by the company.

 retrospective effect from 01.04.2008. In its order PNGRB stated that
 the modalities and time frame for refund of differential Network Tariff

 the judgement in this case on 01.06.2012 and has quashed the PNGRB
