(specially concurring).
I concur.
I write specially on Issue Three to support the conclusion that Strand was entitled to prejudgment interest because his claim was certain or capable of being made certain by calculation through reference to prevailing markets for labor, materials, or values. SDCL 21-1-11. This determination is not changed by the assertion of an unliquidated counter-claim. Therefore, I question the dictum set forth at the close of Issue Three concerning a “different” result if the counter-claim had been successful. If relevant, I would follow the decisional rules set forth in Justice Morgan’s dissent in First Nat’l Bk. of Minneapolis v. Kehn Ranch, 394 N.W.2d 709, 721 (S.D.1986) (Morgan, J., concurring in part, concurring in result in part, and dissenting in part).
