Party admission
The rationale for the rule

The rationale for a party admission exception to hearsay exclusion can be mostly easily understood by reference to the rationale for the hearsay rule itself. Affidavit evidence consisting of out-of-court statements is not subject to cross-examination. Affidavit evidence is thought to detract from the truth-finding mission of a trial. The accuracy or credibility of affidavits lack the transparency that cross-examination exacts, but—at least in civil cases—a party may be cross-examined or give an explanation or denial of its admission. In criminal cases, however, "modern psychological interrogation techniques can cause innocent suspects" to falsely admit to crimes. Therefore, depending on the context, party admissions may advance, rather than detract from, the truth-finding mission.
