"This (K.S.A. 60-460(j )) broadens our former law in the realm of declarations against interest by those not parties to the action nor in privity with a party to the action, as exceptions to the hearsay rule. Formerly there was a requirement of unavailability of the declarant as a prerequisite for reception of this character of testimony, and declarations were limited to those against the pecuniary or proprietary interest of the declarant (Hurley v. Painter, 182 Kan. 731, 324 P.2d 142). [6 Kan.App.2d 425] Now, the statute dispenses with the requirement of unavailability and expands the interests to include penal or social. "The statute does, however, require, as a preliminary measure of trustworthiness, that the trial judge, prior to admission of such a declaration, make a finding that the character of the declaration was of such nature a reasonable man would not make it unless he believed it to be true.
