Headnotes†
Electricity Act, 2003 – Electricity Appeals – When experts 
bodies like the CERC, the APTEL and the Central Electricity 
Authority have taken a particular view:
Held: When various expert bodies like the CERC, the APTEL 
and the Central Electricity Authority after considering the relevant 
material on record have taken a particular view, the Court should 
be slow in interfering with the decisions taken by them – Unless 
the Court finds that the expert bodies have failed to take into 
consideration the mandatory statutory provisions or if their decisions 
are based on extraneous considerations or they are ex facie arbitrary 
and illegal, it will not be appropriate for this Court to substitute its 
views with that of the expert bodies. [Para 20]
Electricity Act, 2003 – s.125 – Code of Civil Procedure, 1908 – 
s.100 – Appeal u/s.125, when permissible:
Held: The appeal u/s.125 of the 2003 Act is only permissible on 
any of the grounds as specified in s.100 of the CPC – As such, 
it is permissible only on substantial questions of law. [Para 23]
Electricity Act, 2003 – ss.79, 125 – The two instant appeals 
challenge the same judgment and final order of the APTEL – 
The first appeal being Civil Appeal No. 1929 of 2020 has been

filed by Haryana Power Purchase Centre and two others 
(HPPC) whereas the second appeal being Civil Appeal No.3429 
of 2020 has been filed by one GRIDCO – Earlier, Petition 
No.79/2013 came to be filed by GKEL-respondent no.1 before 
CERC against the Haryana Utilities for compensation due to 
force majeure events and change in law during the operation 
period – In the said petition, the GKEL-respondent no.1 sought 
adjustment of tariff on account of events of Change in Law 
which affected the power project during the operation period 
in order to restore GKEL to the same economic position that 
it would have been in if the concerned events had never 
occurred – CERC vide order dt. 03.02.2016 disposed of the 
said petition by allowing all such claims which fell within the 
parameters of Change in Law events – GKEL had preferred a 
similar petition being Petition No.112/MP/2015 against Bihar 
Utilities, the CERC vide order dt. 07.04.2017 disposed of the 
petition by allowing all such claims – The CERC vide another 
order dated 20.03.2018 disposed of the Petition No. 105 by 
directing the Haryana Utilities to pay the supplementary bills 
raised by GKEL – Appeals before the APTEL – The APTEL 
vide the common judgment and final order dated 20.12.2019 
dismissed both the appeals and upheld the order of the 
CERC – Correctness:
Held: In the first Appeal No. 1929 of 2020, there are concurrent 
findings of facts not only in the impugned judgment passed by the 
APTEL and the order passed by the CERC in Petition No.105, 
but also in the order dated 03.02.2016 passed by the CERC in 
Petition No.79 during the first round of litigation – The Court will, 
therefore, have to be very slow in interfering with the said findings 
of fact – Unless it is found that the findings are perverse, arbitrary 
or in violation of the statutory provisions, it will not be permissible 
for this Court to interfere with the same – Also, this Court does 
not find any substantial question of law arises for consideration 
in the present appeal – The petition was filed by GKEL seeking 
relief on account of Change in Law on various grounds – One 
of the grounds was with regard to deviations from the New Coal 
Distribution Policy, 2007 (the NCDP) and changes in coal distribution 
policy of the Government of India and Coal India Limited – The 
perusal of paragraphs 54, 55 and 73 of the order passed by the 
CERC dated 03.02.2016 would reveal that it devised a formula 
for computing the Energy Charge Rate which required pro rata
