What is the test for admitting a diary as an exception to the hearsay rule?

The diary should not have been admitted as a business record exception to the hearsay rule. It was not prepared in the regular course of a business activity, nor was it used in the routine operation of the business or agency. The diary is replete with instances of hearsay and multiple hearsay and non-expert opinion which is not independently admissible. Further, a document prepared for purposes of litigation is not a business record because it is lacking in trustworthiness. Palmer v. Hoffman, 318 U.S. 109, 63 S.Ct. 477, 87 L.Ed. 645 (1943).
