(Miscellaneous Application No.1721/2023 in C.A. No.8378/2018)
DECEMBER 04, 2023

HEADNOTES
 Issue for consideration: Effect of letter dtd.24.05.2011 produced 
by the applicants herein in computing Hypothetical Regulatory Asset 
Base (HRAB). As prayed, judgment in Delhi International Airport 
Limited v. Airport Economic Regulatory Authority of India whether to 
be modified or the matter to be remitted to TDSAT to examine the effect 
of the aforesaid letter for the limited issue qua computation of HRAB.
Computation of Hypothetical Regulatory Asset Base (HRAB) 
– Effect of letter dtd.24.05.2011 – Controversy in relation to 
computation of HRAB was set out in Delhi International Airport 
Limited v. Airport Economic Regulatory Authority of India 
reported as [2022] 11 SCR 869 – View adopted by Airport Economic 
Regulatory Authority of India (AERA) and TDSAT received 
imprimatur of this Court– Now, an internal correspondence, a letter 
dated 24.05.2011 between the Ministry of Civil Aviation and AERA 
is produced by the applicants stating to have given rise to an error 
apparent on the face of the record in the aforesaid judgment – Plea 
of the applicants inter alia that the letter relates back to the core 
issue of calculation of HRAB by the method of back solving and 
this Court had confined its finding to the expression “pertaining 
to aeronautical services” but the aspect of ‘single till’ was not dealt 
with and that HRAB should be computed on the basis of ‘single 
till’ mechanism – Judgment in Delhi International Airport Limited 
whether to be modified or the matter to be remitted to TDSAT to 
803
examine the effect of the letter dtd. 24.05.2011 for the limited issue 
qua computation of HRAB:
Held: The nature of jurisdiction exercised by this Court is predicated 
on two specialist authorities/tribunals having applied their mind to it – It 
would be diffi  cult to have a re-appreciation of evidence and facts, especially 
when admittedly the TDSAT has not opined on it – Not appropriate to 
venture into this aspect – However, the letter being in the nature of an 
internal communication privy to the non-applicants, should have been 
placed before the concerned authorities – It would be diffi  cult to say at this 
stage whether it has any impact or not, until the opinion of the TDSAT is 
available – Eff ect of this document to be examined by the TDSAT – TDSAT 
may for the limited issue qua computation of HRAB examine the eff ect of 
the letter dtd. 24.05.2011, and take its own independent view on the impact 
of the same in computing HRAB and whether ‘single till’ mechanism should 
be the basis of the computation. [Paras 14, 15]
