California Penal Code 141 PC makes it illegal to tamper with, alter, conceal, or plant evidence in any legal proceeding.
Because evidence plays a critical role in criminal investigations and court cases, interfering with evidence is considered a serious offense.
Under this statute, a person commits a crime if they knowingly and intentionally manipulate evidence in a way that could cause someone to be falsely accused or if the altered evidence is presented as genuine during a trial or legal inquiry.
The law applies not only to criminal cases but also to civil cases, administrative hearings, and other legal proceedings where evidence may be used.

Different Penalties Depending on Who Commits the Crime
Penal Code 141 treats civilians, police officers, and prosecutors differently in terms of penalties.
Civilian Offenders

Possible penalties include:
-
up to 1 year in county jail
-
a fine of up to $1,000
-
probation
Law Enforcement Officers
If a police officer plants or manipulates evidence, the crime becomes a felony.
Penalties may include:
-
2, 3, or 5 years in state prison
This harsher punishment reflects the serious breach of public trust involved.
Prosecutors
If a prosecuting attorney intentionally modifies or conceals evidence in bad faith, they may also face felony charges.
Possible penalties include:
-
16 months, 2 years, or 3 years in state prison
Examples of Evidence Tampering
Evidence tampering can occur in many different situations.
Examples include:
-
placing illegal drugs in someone else's car to frame them
-

planting a weapon at a crime scene

deleting digital files that could prove someone's innocence

Legal Defenses to Penal Code 141 Charges
Several defense strategies may be used depending on the circumstances of the case.
Lack of Intent
The prosecution must prove that the defendant intentionally manipulated evidence. If the action was accidental or unintentional, the charges may not be valid.
Mistake of Fact
If a person reasonably believed their actions were lawful or did not realize the item was evidence, this may serve as a defense.
False Accusation
In some situations, a person may be falsely accused by someone attempting to shift blame.
Insufficient Evidence
Prosecutors must prove every element of the crime beyond a reasonable doubt. If the evidence is weak or inconsistent, charges may be dismissed or reduced.
Misidentified Evidence
The defense may argue that the alleged evidence was not actually altered, planted, or connected to the accused.
Can Charges Be Avoided Through Prefiling Intervention?
In some situations, a defense attorney may be able to intervene before formal charges are filed. This process is often called prefiling intervention.
During this stage, attorneys may present evidence or legal arguments to prosecutors showing that the case cannot be proven beyond a reasonable doubt.
If successful, prosecutors may decide not to file charges, sometimes referred to as a “DA reject.”
