The first is Phillips v. Ratley, 6 Kan. App. 2d 157, 627 P. 2d. 339 (1981) and the other is Iola State Bank v. Bolan, 235 Kan. 175, 679 P. 2d 720 (1984).
These cases hold that the principal and pre-judgment interest (under 16-201) are to be added together to form a new principal amount which bears interest at the judgment rate. This is not so if there is interest under a contract. There, the judgment bears interest at the contract rate and the interest is applied only to the original principal amount.
