When people think of a criminal prosecution in Washington, they often picture the elected county prosecuting attorney handling the case. In reality, many different attorneys and authorized individuals may appear on behalf of the State. CrR 1.4 provides a simple but important definition that clarifies who the term “prosecuting attorney” includes throughout the Washington Superior Court Criminal Rules.
Although the rule contains only one sentence, it helps ensure that the criminal justice system functions efficiently by recognizing that prosecutorial duties are often performed by deputy prosecutors or other individuals authorized by law.
What Does CrR 1.4 Say?
CrR 1.4 states:
“Whenever used in these rules, prosecuting attorney shall include deputy prosecuting attorneys, or such other person as may be designated by statute.”

Why the CrR 1.4 Prosecuting Attorney Definition Matters
At first glance, this rule may seem purely administrative. However, it serves several important purposes.
Deputy Prosecutors Can Perform Official Duties
Most criminal cases are not personally handled by the elected county prosecutor. Instead, deputy prosecuting attorneys appear in court, negotiate plea agreements, file motions, and conduct trials.
Without CrR 1.4, parties might argue that certain procedural rules apply only to the elected prosecutor. The rule eliminates that uncertainty by making clear that references to the “prosecuting attorney” include deputy prosecutors.
Statutorily Authorized Individuals May Also Act
The rule also recognizes that Washington statutes may authorize other individuals to perform prosecutorial functions.
This language provides flexibility for circumstances where another attorney or official has statutory authority to prosecute a case. Rather than requiring every criminal rule to list every possible authorized prosecutor, CrR 1.4 incorporates those statutory designations automatically.
How CrR 1.4 Affects Criminal Cases
Because the definition applies throughout the Superior Court Criminal Rules, it impacts numerous stages of a criminal case, including:
- Filing criminal charges
- Responding to defense motions
- Negotiating plea agreements
- Participating in hearings
- Conducting jury trials
- Appearing during sentencing proceedings
Whenever another criminal rule assigns a responsibility to the “prosecuting attorney,” CrR 1.4 clarifies that those responsibilities may be carried out by deputy prosecutors or another person authorized by statute.
What This Means for Defendants
For defendants, CrR 1.4 generally does not change the rights available in a criminal case. Instead, it clarifies who may exercise the State’s authority under the court rules.
Whether you are negotiating a plea agreement, attending an arraignment, or preparing for trial, the attorney appearing on behalf of the State is typically a deputy prosecuting attorney acting with the same authority recognized by CrR 1.4.
If questions arise regarding whether a particular individual has authority to prosecute a case, that authority may depend on the applicable Washington statutes in addition to the court rules.
CrR 1.4 Keeps Washington Criminal Procedure Consistent
Many court rules repeatedly refer to the “prosecuting attorney.” Rather than redefining that term every time it appears, CrR 1.4 provides a single definition that applies throughout the Superior Court Criminal Rules.
Although brief, this rule promotes consistency, avoids unnecessary disputes over terminology, and ensures that criminal proceedings can move forward efficiently with authorized representatives of the State.
