Making a false report of a crime to law enforcement, prosecutors, or emergency dispatch personnel is a serious misdemeanor under California law. California Penal Code 148.5 PC criminalizes knowingly providing false information about a felony or misdemeanor to individuals responsible for receiving crime reports.
Whether an individual makes an unsolicited false report or intentionally provides false statements as a witness during an active investigation, California law treats this conduct as a harmful waste of public resources and an illegal accusation against innocent people.
However, Penal Code 148.5 PC requires proof that the person knew the report was false at the time it was made; an honest mistake or a reasonable belief that a crime occurred does not constitute a criminal offense.
Legal Definition: PC 148.5 PC
The legal definition language under California Penal Code Section 148.5 PC states:
(a) Every person who reports to any peace officer listed in Section 830.1 or 830.2, or subdivision (a) of Section 830.33, district attorney, or deputy district attorney that a felony or misdemeanor has been committed, knowing the report to be false, is guilty of a misdemeanor.
(b) Every person who reports to any peace officer that a felony or misdemeanor has been committed, knowing the report to be false, is guilty of a misdemeanor if (1) the false information is given while the peace officer is engaged in the performance of his or her duties as a peace officer and (2) the person providing the false information knows, or reasonably should know, that the person receiving the information is a peace officer.
(c) Every person who reports to any employee who is assigned to accept reports from the public, either directly or by telephone, and who is employed by a state or local agency which employs peace officers... that a felony or misdemeanor has been committed, knowing the report to be false, is guilty of a misdemeanor if (1) the false information is given while the employee is engaged in the performance of his or her duties as an employee and (2) the person providing the false information knows, or reasonably should know, that the person receiving the information is an employee described in this subdivision.
(d) Every person who makes a report to the grand jury that a felony or misdemeanor has been committed, knowing the report to be false, is guilty of a misdemeanor. This subdivision shall not be construed as prohibiting in any way a person from presenting of evidence or information to the grand jury.
Key Statutory Definitions
Understanding how Penal Code 148.5 PC is applied requires breaking down its core legal terminology as outlined in California Judicial Council Criminal Jury Instructions (CALCRIM No. 2655):
-
Peace Officer / Law Enforcement Employee: Includes municipal police officers, county sheriff's deputies, California Highway Patrol (CHP) officers, prosecutors, district attorney investigators, and administrative employees trained to take crime reports from the public (such as 911 dispatch operators or station desk clerks).
-
Knowing Knowledge of Falsity: The explicit mental state (mens rea) requiring the prosecution to prove the defendant had actual knowledge that the reported crime was fabricated when the statement was made.
-
Felony or Misdemeanor Report: Any false claim alleging that a criminal offense occurred, ranging from petty theft or vandalism to violent crimes like domestic battery or assault.
-
Direct vs. Third-Party False Witness Statements: PC 148.5 applies to both individuals who initiate a false report (e.g., by calling 911) and third parties who voluntarily give false witness statements or accuse the wrong person during an ongoing police investigation.
What Must Be Proven to Convict
To secure a conviction under California Penal Code 148.9 PC / 148.5 PC, prosecutors must establish the following elements beyond a reasonable doubt (CALCRIM No. 2655):
-
Filing a Report: The defendant made or caused to be made a report that a misdemeanor or felony offense had been committed.
-
Proper Recipient: The report was made to a peace officer, district attorney, deputy attorney general, grand jury, or agency employee assigned to accept crime reports (such as a 911 operator).
-
Knowledge of Falsity: The defendant knew the report was false at the time they made it or provided the information.
-
Performance of Duties: The recipient of the report was performing their official duties, and the defendant knew, or reasonably should have known, that the recipient was an authorized officer or law enforcement employee.
Penalties for Penal Code 148.5 PC
Filing a false police report under PC 148.5 is classified strictly as a misdemeanor offense in California.
If convicted under PC 148.5, potential statutory penalties include:
-
Up to 6 months (180 days) in county jail.
-
Criminal fines of up to $1,000 (plus state penalty assessments).
-
Summary (Informal) Probation: Judges frequently order probation instead of jail time, which may include conditions such as community service, mandatory counseling, or restitution payments to reimburse law enforcement for wasted emergency resources.
Key Defense Strategies: California Penal Code 148.5 PC
To secure a conviction under California Penal Code 148.5 PC, the prosecution must prove every statutory element beyond a reasonable doubt. A skilled criminal defense attorney can challenge the state's case using several legally recognized defense strategies.
Good-Faith Reasonable Belief / Lack of Knowledge
Penal Code 148.5 PC requires the prosecution to prove that the defendant knew the report was false when it was made. If the defendant made an honest mistake, relied on inaccurate information from a third party, or reasonably believed a crime had actually occurred, they cannot be convicted. Defense counsel presents evidence, text messages, or witness accounts showing that the accused acted in good faith based on their perception at the time.
Truthfulness of the Reported Information
A defendant cannot be guilty of filing a false police report if the reported criminal conduct actually occurred or if the core facts provided to law enforcement were accurate. Defense attorneys investigate the underlying allegations, gather surveillance video, or interview witnesses to corroborate the defendant's original statements and prove the report was factually accurate.
Coercion, Duress, or Intimidation
If an individual was forced, threatened, or coerced by a third party into filing a false police report—such as an abusive partner forcing someone to report a fake vehicle theft for insurance proceeds—the defense of duress applies. Establishing that the defendant acted out of an immediate fear of harm excuses criminal liability under California law.
Recipient Was Not an Authorized Employee or Duty Status Defect
PC 148.5 specifically requires the report to be made to a peace officer, prosecutor, 911 operator, or designated law enforcement report taker engaged in their duties. If the statement was made to a private security guard, an off-duty officer who did not identify themselves, or a party uninvolved with law enforcement reporting, the statutory requirements are not met.
Hypothetical Examples
-
Insurance Fraud / False Auto Theft: A car owner hides her vehicle in a remote garage and calls 911 to report it stolen to file a fraudulent auto insurance claim, violating PC 148.5.
-
Child Custody Dispute Fabrication: During a contested custody hearing, a parent fabricates allegations of domestic violence and calls police to get the other parent arrested, exposing themselves to PC 148.5 misdemeanor charges.
-
Misidentified Witness Statement: A bystander who observes a street fight deliberately lies to investigating officers by blaming an innocent neighbor he dislikes, committing a false report offense as a third-party witness.

Frequently Asked Questions
Can you be charged under PC 148.5 if you honestly believed a crime had occurred? No. Penal Code 148.5 PC requires actual knowledge that the report was false. If you made an honest mistake or had a reasonable belief that a crime took place, you are not guilty of a crime.
What is the maximum jail time for making a false police report in California? A conviction for misdemeanor PC 148.5 carries a maximum sentence of 6 months in county jail, along with potential fines of up to $1,000 and probation.
Can giving a false statement as a witness be charged under PC 148.5? Yes. You do not have to be the person who initially called 911. Intentionally providing false witness statements or identifying the wrong person to an investigating officer constitutes a false report under PC 148.5.
Is making a false domestic violence report a crime? Yes. Falsely accusing a partner or spouse of domestic abuse to get them arrested or to gain leverage in a child custody dispute is a common scenario prosecuted under Penal Code 148.5 PC.
What is the difference between PC 148.5 and PC 148.3 (False Emergency)? PC 148.5 applies to false reports of general crimes (felonies or misdemeanors). PC 148.3 specifically applies to false reports of active emergencies (such as swatting), which carries severe felony penalties if someone is injured or killed.
Can police charge you with PC 148.5 if you retract a false report? While recanting or correcting a false statement quickly may help your defense and show a lack of bad intent, technically the crime is complete once the false report is knowingly communicated to an officer.
What should I do if a police detective calls to ask about a report I filed? If an investigator contacts you questioning the validity of a crime report you made, politely decline to answer questions without an attorney present. Detectives often use follow-up calls to gather admissions to build a PC 148.5 case against you.
