All three appeals impugn separate orders passed by the learned Single judge on applications filed by the respondents under Section 34 of the Arbitration and Conciliation Act, 1996 (hereafter, "the Act"). The common strain in all the appeals is that since the respondents/contractors had accepted the final bills without protest, their claims could not have been entertained. The awards granted in favour of such respondent/claimants (hereafter collectively "claimants", "contractors" or by their names, i.e. "Sukumar, "GSC" and "Kuber").

The correctness of the learned single judge's order and judgment, in OMP 399/2007 preferred by the respondent Delhi Development Authority (hereafter referred as "DDA") under Section 34 of the Act is questioned in this appeal.

The claimant was awarded the work of construction of 8314 houses in Sector-XV, Rohini, Delhi, SH & Construction of 252 LIG houses in Pocket Nos. 6 & 7, Block- G, Sector XV, Rohini, Delhi by DDA by letter dated 16.12.1985.
