When someone in Washington State chooses to contest a notice of infraction — such as a traffic ticket — the process is not simply a matter of showing up in court. There are procedural safeguards and obligations that both the defendant and the prosecuting authority must follow. IRLJ 3.1 is the rule that governs contested hearings‑‑preliminary proceedings in infraction cases in Washington’s courts of limited jurisdiction, setting standards for subpoenas, discovery, amendments, and sufficiency of notice.
What IRLJ 3.1 Covers
IRLJ 3.1 sets out the rules for the procedural steps that take place before and during a contested infraction hearing. The rule helps ensure that both sides have fair notice and an opportunity to prepare their case. Among its key components are:
1. Subpoena of Witnesses
Both the defendant and the prosecuting attorney can subpoena witnesses whose testimony is necessary for presenting their respective cases.
- Subpoenas should be served at least seven (7) days before the hearing.
- A subpoena may be issued by a judge, court commissioner, clerk of the court, or a party’s lawyer — provided a copy is filed with the court and prosecuting authority.
- Subpoenas can be served within the jurisdiction of the issuing court, or via first‑class mail to the witness’s last known address.
- If the witness lives outside the county, a judge must approve the subpoena.
These provisions ensure that the parties can bring forward testimony that supports their position at a contested hearing.
2. Discovery Procedures
IRLJ 3.1 also establishes limited discovery rights: upon written demand by the defendant at least 14 days before the hearing, the prosecuting authority must provide, at least 7 days before the hearing:
- A copy of the citing officer’s sworn statement;
- Copies of video or photographic evidence the prosecutor intends to use (or access instructions if hosted online);
- The names of any witnesses not identified earlier in the officer’s sworn statement.
If materials are provided late without justification, the court may suppress that evidence if the defendant is prejudiced by the delay. Evidence not provided at all may be suppressed unless the prosecutor has a reasonable excuse.
This limited discovery framework protects a defendant’s right to review the evidence against them, while balancing the expedited nature of infraction hearings.
3. Amendment of Notice
The court may allow a notice of infraction to be amended before judgment if:
- No additional or different infraction is charged, and
- The defendant’s substantial rights are not prejudiced by the change.
If an amendment is allowed and additional preparation time is needed, a continuance must be granted at the defendant’s request.
4. Sufficiency of Notice
Even if a notice of infraction has defects — such as imperfect phrasing, omissions, or minor technical errors — it shall not be deemed insufficient for that reason alone if those issues do not prejudice the defendant’s substantial rights.
This provision reinforces the idea that procedural fairness matters more than hyper‑technical errors that don’t impact the defendant’s ability to respond.
Why IRLJ 3.1 Matters
IRLJ 3.1 plays a critical role in ensuring fairness in contested infraction hearings in Washington:
- It allows defendants to compel relevant testimony, including from police officers or other witnesses.
- It ensures defendants have access to critical evidence before a hearing.
- It permits amendments to correct mistakes without unfair prejudice.
- It guards against overly technical challenges when the notice still provides a fair opportunity to prepare a defense.
Together, these rules balance the court’s interest in efficient infraction resolution with a defendant’s right to meaningful participation and defense.
