High Court of Karnataka, Dharwad Bench (DB: R. Nataraj J., author, with Rajesh Rai K. J.), 20.11.2025 - RFA No.100494/2018 by Karnataka Neeravari Nigam Ltd. and its engineers against the decree in O.S.No.260/2003 (I Addl. Senior Civil Judge & CJM, Dharwad), c/w contractor's RFA CROB No.100003/2023 claiming 18% interest. Contract (work order 07.05.1993) for balance work of Malaprabha Right Bank Canal at Km.113; accumulated silt gave rise to an 'extra item' dispute (paid 27.03.1997 at Rs.23/cum under Clause 38); work delayed about seven years, completed 10.06.2001, final bill paid 2003 under protest. Held: (i) after withdrawal of O.S.No.212/2000 under Order XXIII Rule 1(3) CPC with liberty, a fresh suit was justified - the Trial Court did not relegate the plaintiff to arbitration and the suit followed completion and part payment; (ii) joinder under Order II Rule 3 CPC being permissive, the causes of action of both suits could be united; (iii) the suit is within limitation, Article 55 Limitation Act 1963 applying to a continuing breach that ceased on the 2003 final-bill settlement; (iv) absence of a fresh Section 80 CPC notice is not fatal, the reliefs being against officers of KNNL, a wholly State-owned government company, and Section 80 notice having been given before O.S.No.212/2000; (v) on quantum: Rs.12,30,360 for silt/slush removal upheld; revised rates for post-stipulation work upheld (K.N. Sathyapalan (2007) 13 SCC 43 applied); penalty of Rs.13,650 refundable; idling charges restricted to Rs.2,50,000 lump sum for labour and tools, the machinery-idling claim failing for want of hard evidence (Ircon International and North Delhi Municipal Corporation relied on; Hudson/Emden/Eichleay formulas per McDermott International noted); overheads cut from the claimed 15% to 5%, i.e., Rs.18,44,242 (Batliboi Environmental Engineers applied); loss-of-expected-profit denied but Rs.5,00,000 awarded for lost tendering opportunity plus Rs.6,158 bank-guarantee commission; lead charges of Rs.110.26/cum for Yavagal murrum allowed; interest reduced from 18% to 9% p.a. from 10.06.2001 (proviso to Section 34 CPC; I.K. Merchants applied). Decree modified to Rs.82,28,660.90 with 9% interest; both appeals allowed in part with proportionate costs.
