In this article, I propose two changes in the way hearsay issues are usually resolved. First, in some circumstances courts should divide the burdens of producing the declarant-for example, by imposing the physical burden on the proponent and the financial burden on the opponent. Second, no matter how the declarant is produced as a witness, she should ordinarily testify as part of the proponent's case, subject to cross-examination by the opponent. If the declarant does become a witness, the admissibility of her out-of-court statement should not be resolved until her current testimony about the underlying events is received.
