What Is RCW 2.42.160?
RCW 2.42.160 is a Washington statute within Chapter 2.42 – Interpreters in legal proceedings. This section focuses on privileged communication — that is, communications protected by law from disclosure — when a qualified or intermediary interpreter is involved.
Under this law:
- A qualified or intermediary interpreter cannot be compelled to testify about privileged communications they interpreted unless all parties to that communication have written consent.
- The interpreter also may not be questioned about any information obtained through interpretation pertaining to a pending proceeding without that same written consent.
In practice, this protects confidentiality when interpreters work with individuals in situations where legal privilege applies (e.g., attorney‑client conversations).*
Why Privileged Communication Matters in Court
Preserving Fair Process
In legal and administrative settings, certain communications are protected by privilege — for example:
- attorney‑client communications,
- communications between a client and their legal representative, and
- other legally recognized confidential interactions.
When interpreters are involved, they may hear or translate communications that should remain confidential. RCW 2.42.160 preserves that confidentiality, ensuring interpreters are not inadvertently turned into witnesses against a party whose communication was privileged.
Clarifying “Qualified” and “Intermediary” Interpreters
Under the broader Chapter 2.42, Washington law defines:
- a qualified interpreter as someone certified to interpret accurately for hearing or speech‑impaired persons, and
- an intermediary interpreter as someone assisting when communication modes are particularly complex.
Both types are covered by RCW 2.42.160’s protections regarding privilege.
When RCW 2.42.160 Applies
Court Proceedings
If a hearing‑impaired party is involved in a civil, criminal, juvenile, licensing, or administrative proceeding, an interpreter must be appointed and, once involved, is subject to the protections in RCW 2.42.160.
Privilege in Ongoing Cases
The statute also prevents examination of interpreters about information they learned during interpretation in a still‑pending proceeding, ensuring that the very act of interpreting does not expose sensitive material unless the involved parties agree in writing.
Written Consent Requirement
The key trigger for RCW 2.42.160 is written consent by all parties to the privileged communication. Without such consent, neither privileged communications nor the interpreter’s related knowledge can be probed, even through deposition or at trial.
Practical Considerations for Attorneys and Interpreters
Legal counsel should:
- ensure interpreters understand their rights and limitations under this statute,
- obtain written consent when appropriate, and
- consider privilege implications during case strategy.
Interpreters should be trained on confidentiality and privileged communication to avoid inadvertent violations.
