Disqualification of a Judge for Prejudice – CCP 170.6 Explained
California Code of Civil Procedure 170.6 allows a party in a civil or criminal case to disqualify a judge based on perceived prejudice.
This process, known as a peremptory challenge, is a powerful legal tool that does not require proof of actual bias.
Instead, a party may request a new judge simply by declaring under oath that they believe they cannot receive a fair trial before the assigned judge.
Once properly filed, the judge must be removed from the case, and the matter reassigned to another judge.

Quick Answer: What Is CCP 170.6?
CCP 170.6 allows a party to disqualify a judge without proving bias by filing a timely peremptory challenge stating the judge is prejudiced.
What Does It Mean to Disqualify a Judge?
Disqualifying a judge means removing that judge from presiding over a case and assigning a different judge to handle the proceedings.
In California, this can occur when a party believes the assigned judge cannot be fair, impartial, or neutral in deciding the issues in the case.
Judicial disqualification is an important safeguard in both civil and criminal cases.
It ensures that every party receives a fair hearing before an unbiased decision-maker, which is a fundamental requirement under California law and constitutional due process principles.
Why Disqualification Matters
The outcome of a case can be significantly influenced by the judge overseeing it. Even if bias cannot be proven, California law allows parties to act proactively to protect their right to a fair trial.
Disqualification helps:
- Maintain confidence in the judicial system
- Prevent unfair rulings or prejudice
- Ensure equal treatment of all parties
- Uphold due process rights
When Disqualification Is Used
A judge may be disqualified in several situations, including:
- When a party believes the judge is prejudiced against them or their attorney
- When the judge has a conflict of interest in the case
- When the judge has prior involvement in the matter
- When facts exist that could reasonably question the judge's impartiality
In California, this can be done through either a peremptory challenge under CCP 170.6 or a for-cause challenge under CCP 170.1.
Example Scenario
A defendant in a criminal case believes the assigned judge has demonstrated bias in similar cases involving the same type of charges. The defense files a motion under CCP 170.6, and the judge is removed from the case without requiring proof of bias.
Key Takeaway
Disqualifying a judge does not mean wrongdoing has been proven. Instead, it is a legal mechanism designed to ensure fairness by allowing a case to proceed before a judge who is free from any appearance of bias or conflict.
What Is a Peremptory Challenge?
A peremptory challenge under CCP 170.6 allows a party to remove a judge without providing evidence of bias.
Key features include:
- No proof of prejudice is required
- The party must declare a belief that the judge is biased
- The judge must step aside if the motion is properly filed
- Each side is typically allowed one peremptory challenge
This makes CCP 170.6 one of the most straightforward ways to request a new judge.
How to Disqualify a Judge Under CCP 170.6
To successfully remove a judge by peremptory challenge, strict procedural requirements must be met.
Step 1: File a Motion to Recuse
A written motion must be filed stating that the judge is prejudiced against a party or attorney.
Step 2: Use Required Statutory Language
The motion must include the language required under CCP 170.6 to be valid.
Step 3: File Within the Deadline
Timing is critical. The motion must generally be filed:
- Before the trial begins, and
- Within a limited time after receiving notice of the judge assignment, often within 10 days
Step 4: Avoid Substantive Rulings
The challenge must typically be made before the judge decides contested issues.
Step 5: Case Reassignment
If the motion is properly filed, the judge is automatically disqualified, and the case is reassigned.
Example Scenario
A defendant in a criminal case believes the assigned judge may be unfavorable based on prior rulings in similar cases. The defense files a timely CCP 170.6 motion asserting that the judge is prejudiced. The court grants the motion and assigns a new judge.
Peremptory Challenge vs. Challenge for Cause
California law provides two main methods for disqualifying a judge.
Peremptory Challenge – CCP 170.6
- No evidence of bias required
- Based on a party's sworn statement of prejudice
- Limited to one challenge per side
- Must be timely filed
Challenge for Cause – CCP 170.1
A challenge for cause requires proof of actual bias or conflict of interest.
Common grounds include:
- Personal knowledge of disputed facts
- Prior involvement as an attorney in the case
- Financial interest in the outcome
- Family or professional relationships with parties or attorneys
Unlike peremptory challenges, there is no strict limit on the number of for-cause challenges, but they require supporting evidence.
