Penal Code § 141 PC - Evidence Planting or Tampering
1. What is Penal Code § 141 PC?
Penal Code § 141 PC Law Reads As Followed:
(a) Except as provided in subdivisions (b) and (c), a person who knowingly, willfully, intentionally, and wrongfully alters, modifies, plants, places, manufactures, conceals, or moves any physical matter, digital image, or video recording, with the specific intent that the action will result in a person being charged with a crime or with the specific intent that the physical matter will be wrongfully produced as genuine or true in a trial, proceeding, or inquiry, is guilty of a misdemeanor.
2. What Are Examples of Penal Code § 141 PC?
Penal Code § 141 PC criminalizes planting or tampering with evidence with the intent to mislead investigators or influence a legal proceeding. Understanding what counts as a violation is essential, as even seemingly minor actions can lead to serious criminal charges.
Below, our California criminal defense attorneys explain common examples of conduct that can constitute a § 141 PC violation.
1. Planting Evidence to Frame Someone
One of the most straightforward examples of a § 141 PC violation is planting evidence on another person to make it appear they committed a crime.
Example:
- Sarah wants to get revenge on her neighbor, Mark. She secretly places illegal drugs in Mark’s car, hoping law enforcement will find them and arrest him.
- By planting the drugs with the intent that Mark be charged, Sarah has committed a crime under Penal Code § 141 PC.
2. Altering or Modifying Evidence
Tampering with evidence also includes changing or modifying physical or digital evidence to mislead investigators or influence court proceedings.
Example:
- John alters a surveillance video to remove footage showing him committing a theft, then submits the edited video in a civil case.
- Because he knowingly altered evidence to mislead a legal process, John may be charged under § 141 PC.
3. Hiding or Concealing Evidence
Intentionally hiding or concealing evidence so that it cannot be discovered is another violation of § 141 PC.
Example:
- During a divorce, Lisa hides financial documents her spouse could use to prove marital misconduct.
- Even though this may not involve a criminal trial, it is still considered evidence tampering if her intent is to mislead the court.
4. Moving Evidence
Moving or relocating evidence to a different location with the intent to deceive investigators or the court can also violate Penal Code § 141.
Example:
Tom finds stolen property at his friend’s house but moves it to his own home to make it appear the friend is guilty.
Tom’s act of moving evidence with intent to cause false charges makes him criminally liable.
5. Manufacturing or Creating Fake Evidence
Creating false evidence to present in court or an investigation is a serious offense.
Example:
Karen creates a forged document showing she made a large charitable donation, intending to influence the outcome of a probate dispute.
By manufacturing evidence to mislead a legal proceeding, Karen has violated § 141 PC.
6. Examples Involving Digital Media
Evidence tampering is not limited to physical objects. Digital images, videos, or other electronic files can also be manipulated under § 141 PC.
Example:
- Alex edits a photograph to make it appear that his co-worker was stealing office property and submits it to management or law enforcement.
- The act of modifying digital evidence to falsely accuse someone falls under Penal Code § 141.
3. What are Common Defenses Against Penal Code § 141 PC?
Being charged with Penal Code § 141 PC for evidence planting or tampering is serious, as it can affect both criminal and civil proceedings. However, there are several legal defenses that may help a person fight these charges.
Below, our California criminal defense attorneys explain the most common defenses used in § 141 PC cases.
The key element of a § 141 PC violation is intent. To be convicted, the prosecution must prove that you:
- Knowingly and willfully tampered with or planted evidence, and
- Intended either to get someone charged with a crime or to have the evidence falsely presented as genuine in a legal proceeding.
Defense Strategy:
If your actions were accidental or you lacked the specific intent required by law, this can be a strong defense.
Example:
- Maria moved a set of documents from one file to another without realizing they would later be used in a trial.
- Because she lacked intent to deceive the court, she may have a valid defense against a § 141 PC charge.
A mistake of fact occurs when a person acts under a reasonable belief that their conduct is lawful.
Example:
- Tom finds a bag of personal items and moves it to prevent it from being damaged, not realizing law enforcement considers it potential evidence.
- If Tom genuinely did not know his actions would interfere with an investigation or legal proceeding, he may be able to avoid conviction.
3. False Accusation or Misidentification
Sometimes, people are wrongly accused of evidence tampering, often due to misunderstandings or personal conflicts.
Defense Strategy:
- Demonstrate that the alleged evidence planting never occurred.
- Show that any evidence against you was circumstantial, misinterpreted, or fabricated.
Example:
- Alex is accused by a co-worker of planting drugs in their office, but surveillance footage proves he was not present.
- Evidence shows he was falsely accused, which can lead to dismissal or acquittal.
A § 141 PC conviction requires that the defendant knew they were tampering with evidence.
Defense Strategy:
- Argue that you were unaware the object, document, or digital file qualified as evidence.
- Show that you did not understand the legal significance of your actions at the time.
Example:
- Jane discarded an old hard drive containing files she thought were personal, unaware it contained records relevant to a civil investigation.
- Because she lacked knowledge of the evidence’s significance, she may avoid criminal liability.
5. Entrapment
Entrapment occurs when law enforcement or another authority induces a person to commit a crime they otherwise would not have committed.
Example:
- A police officer pressures a person into planting fabricated evidence under the guise of helping with an investigation.
- If entrapment can be proven, it may be a valid defense under § 141 PC.
6. Evidence Was Not Used or Intended for Use
For a § 141 PC violation, the tampered or planted evidence must be intended to be presented in a trial, proceeding, or inquiry.
Defense Strategy:
- Show that the evidence was never meant to be submitted in a legal process.
- Prove that your actions had no connection to any investigation or trial.
Example:
- Sam altered documents for personal reasons unrelated to any legal proceeding.
- Since there was no intent to use the documents in court, the charge under § 141 PC may not stand.

4. What are The Penalties for Violating Penal Code § 141 PC?
Violating Penal Code § 141 PC is a serious crime in California because it undermines the integrity of the legal system. The penalties vary depending on whether the person charged is a private citizen or a law enforcement officer. Understanding the potential consequences is essential for anyone facing these charges.
Below, our California criminal defense attorneys break down the penalties for evidence planting or tampering under § 141 PC.
1. Penalties for Private Citizens
For most individuals, evidence planting or tampering is classified as a misdemeanor.
Possible Consequences Include:
- County Jail: Up to 6 months
- Fines: Up to $1,000
Misdemeanor convictions can also carry additional consequences, such as:
- Probation
- Mandatory community service
- Criminal record, which can affect employment, housing, and professional licensing
Example:
Jane is accused of planting false documents in a civil dispute. If convicted, she could face up to six months in county jail and a $1,000 fine, along with probation or other court-imposed conditions.
2. Penalties for Law Enforcement Officers
If a police officer or other law enforcement official commits evidence tampering, the crime is treated as a felony due to the abuse of authority involved.
Felony Penalties May Include:
- State Prison: 2, 3, or 5 years
- Probation with Jail Time: In some cases, probation may be granted along with a county jail sentence
- Loss of Employment or Certification: Officers convicted of felony evidence tampering may also face termination or revocation of peace officer status
Example:
Officer Jeff plants false evidence to secure an arrest. A conviction could result in multiple years in state prison and permanent damage to his law enforcement career.
3. Related Consequences
In addition to direct criminal penalties, a conviction under § 141 PC can lead to related legal complications, such as:
- Civil Liability: Individuals may be sued for damages resulting from the false evidence
- Enhanced Sentencing: If the act of tampering is part of a broader criminal conspiracy or obstruction of justice case, penalties can increase
- Additional Charges: Perjury, conspiracy, or other obstruction-of-justice crimes may be charged alongside § 141 PC
Penal Code § 141 PC carries significant consequences that depend on:
- The role of the defendant (private citizen vs. law enforcement)
- The scope of the tampering or planting of evidence
- Any related offenses committed during the act
Misdemeanor penalties for private citizens are serious enough to affect your freedom, finances, and future opportunities. Felony penalties for law enforcement officers highlight the importance California places on integrity in public service.
5. What Are the Related Offenses To Penal Code § 141 PC?
Penal Code § 141 PC makes it illegal to plant or tamper with evidence to mislead investigators or influence a legal proceeding. However, many other offenses in California are closely related because they also involve obstruction of justice, falsifying evidence, or interfering with the legal system. Understanding these related offenses is important, as someone charged with § 141 PC may also face additional criminal liability.
Below, our California criminal defense attorneys outline the key related offenses.
1. Conspiracy to Tamper With or Plant Evidence
When two or more people work together to plant or manipulate evidence, they may also be charged with criminal conspiracy.
Key Elements of Conspiracy:
- An agreement between two or more individuals to commit a crime, such as evidence tampering.
- At least one overt act in furtherance of the agreement.
Penalties:
- Can be charged as either a misdemeanor or a felony (wobbler)
- Jail time can range from 16 months (misdemeanor) to several years in state prison (felony)
Example:
Two coworkers plant fake invoices to frame another employee for fraud. Both can be charged with § 141 PC and conspiracy.
2. Offering False Evidence (Penal Code § 132 PC)
Penal Code § 132 PC prohibits presenting false or forged evidence in a legal proceeding. Unlike § 141 PC, this offense focuses on submission of the false evidence, rather than just planting or tampering.
Penalties:
- Felony
- Prison sentence of 16 months, 2 years, or 3 years
Example:
Mark forges a witness statement and submits it in a civil trial. Even if he didn’t plant physical evidence, he can be charged under § 132 PC.
3. Preparing False Evidence (Penal Code § 134 PC)
Penal Code § 134 PC makes it illegal to create false evidence with the intent to use it in a legal proceeding, even if the evidence is never submitted.
Penalties:
- Felony
- Prison sentence of 16 months, 2 years, or 3 years
Example:
Anna fabricates documents proving a financial transaction never occurred, intending to use them in court. This is a crime even if the documents are never actually filed.
4. Destroying or Concealing Evidence (Penal Code § 135 PC)
Penal Code § 135 PC prohibits destroying, hiding, or altering evidence that you know may be presented in a legal proceeding.
Penalties:
- Misdemeanor
- Up to 6 months in county jail and/or $1,000 fine
Example:
Brian discards security footage before it can be reviewed in a criminal investigation. This act may be charged under § 135 PC, in addition to § 141 PC.
5. Perjury (Penal Code § 118 PC)
Perjury occurs when someone knowingly makes a false statement under oath. Often, perjury is connected to evidence tampering because the defendant may lie about the authenticity or origin of evidence in court.
Penalties:
- Felony
- 2, 3, or 4 years in prison
Example:
Emily plants evidence and then testifies under oath that the evidence is genuine. She can be charged with both § 141 PC and perjury.
