When Can Other Evidence Be Used Instead of an Original?
Washington ER 1004 admissibility rules permit other evidence to be introduced when:
- The original document is lost or destroyed, unless bad faith caused the loss.
- The original document is not obtainable by any available judicial process.
- The party against whom the evidence is offered had control of the original but fails to produce it.
- The matter to be proven relates to collateral issues, not critical ones.
In each of these situations, the court permits secondary evidence, such as copies, testimony, or summaries, to replace the original document.
Why Washington ER 1004 Matters in Court
Cases involving contract disputes, wills, or business transactions often hinge on documentary evidence. Without rules like Washington ER 1004, parties could unfairly avoid liability simply by losing or withholding documents.
Washington courts aim to balance fairness with flexibility, allowing parties to prove their case even without the original evidence under well-defined legal standards.
Using the right strategy to invoke ER 1004 can strengthen a plaintiff’s or defendant’s position when documents are unavailable through no fault of their own.
Key Takeaways for Admissibility of Other Evidence
- Loss or destruction must not result from bad faith to allow replacement evidence.
- Judicial unavailability of documents (even with subpoenas) can justify alternatives.
- Collateral matters do not require strict original documentation under Washington ER 1004 admissibility rules.
- Control and non-production by opposing parties opens the door to secondary proof.
Understanding these exceptions can be crucial in personal injury cases, contract disputes, business litigation, and probate matters.
