Mueller on Evidence: Documentary Evidence

Authentication of Documents

This section discusses the requirement of authentication as a prerequisite for the admissibility of documentary evidence. It outlines the methods of authentication, including testimony from a witness with knowledge, a non-expert's opinion about handwriting, and distinctive characteristics of the document. The section emphasizes how these methods establish the document's genuineness.

• Authentication is required for all documentary evidence.
• Various methods of establishing authenticity can be used.

Best Evidence Rule

The Best Evidence Rule dictates that to prove the content of a document, the original document must be produced unless an exception applies. This section clarifies the criteria for determining when a duplicate is permissible, including situations where the original is lost, destroyed, or unobtainable. The chapter also discusses the implications of failing to produce the original document.

• The original document is preferred to establish content.
• Duplicates may be admissible under specific conditions.

Hearsay and Documents

This section examines the intersection of hearsay rules with documentary evidence. It explains how documents can fall under hearsay exceptions, particularly when they are used to prove the truth of matters asserted. The chapter details various hearsay exceptions relevant to documents, including business records, public records, and ancient documents.

• Documents can be considered hearsay depending on their use.
• Certain hearsay exceptions explicitly include documentary evidence.

Parol Evidence Rule

The Parol Evidence Rule addresses the admissibility of oral or written statements made prior to or contemporaneously with a written agreement. This section elaborates on how this rule aims to preserve the integrity of written agreements by preventing parties from altering the terms through prior negotiations or agreements. It also discusses exceptions to the parol evidence rule, such as rectifying ambiguities or showing fraud.

• The written document is the primary source for contract terms.
• Exceptions exist for clarifying intent or addressing fraud.
