New York False Testimony to Harm Defendant

In the State of New York, providing false testimony under oath during an official proceeding is a felony offense. When such testimony occurs during a criminal proceeding and is material to the outcome, it may be charged as Aggravated Perjury. Although the law does not explicitly require intent to harm the defendant, the legal consequences are severe due to the disruption of justice. This article outlines the statutory basis, distinctions from ordinary perjury, punishment ranges, and strategic defenses.

1. New York False Testimony to Harm Defendant | Statutory Basis and Legal Overview


The New York Penal Law treats perjury offenses seriously, particularly when they affect the outcome of a criminal trial.



New York False Testimony to Harm Defendant | Perjury and Aggravated Perjury Defined


Under New York Penal Law § 210.10, a person is guilty of perjury in the second degree when they swear falsely during a proceeding where an oath is legally required. If that false statement is made during a criminal proceeding, is material, and the person knows it to be false, the offense may rise to Aggravated Perjury under § 210.15—a Class C felony.



New York False Testimony to Harm Defendant | Legal Distinctions and Severity


Aggravated perjury differs from ordinary perjury based on context and consequence. A statement made during a criminal trial that could influence the verdict is treated more harshly—even if the person did not intend specific harm to the defendant. The law focuses on the material effect of the falsehood, not the witness’s subjective motivation.

2. New York False Testimony to Harm Defendant | Elements of the Crime and Scope


Establishing a charge of aggravated perjury requires proof of specific statutory components.



New York False Testimony to Harm Defendant | Legal Elements Required


  1. Statement Made Under Oath
    The statement must occur in a proceeding where an oath is legally administered (e.g., court, grand jury).
  2. Knowledge of Falsity
    The individual must be aware that their statement is false when it is made.
  3. Materiality in Criminal Proceedings
    The falsehood must be material—meaning it has a real potential to influence the outcome of a criminal case.

 

There is no legal requirement that the person aimed to harm the defendant. The focus is on the integrity of the justice process.



New York False Testimony to Harm Defendant | Who May Be Charged


Anyone who testifies or provides sworn statements during criminal trials may be charged—witnesses, interpreters, and experts alike—if the legal elements are met. The charge is not limited to hostile or adverse parties.



3. New York False Testimony to Harm Defendant | Sentencing Considerations and Statute of Limitations


Penalties vary depending on the severity and context of the false statement.



New York False Testimony to Harm Defendant | Criminal Classification and Sentence


  • Perjury in the Second Degree: Class E felony, punishable by up to 4 years
  • Aggravated Perjury: Class C felony, punishable by up to 15 years

 

New York judges may also consider aggravating or mitigating circumstances during sentencing, such as:

  • Impact on the trial’s outcome
  • Whether the statement was repeated or coordinated
  • Whether the witness recanted before the verdict


New York False Testimony to Harm Defendant | Statute of Limitations


Under CPL § 30.10(2)(b), the statute of limitations for perjury offenses classified as Class C or E felonies is five years. Statements made more than five years prior to prosecution generally cannot be charged.



4. New York False Testimony to Harm Defendant | Defense Strategies


Legal defenses should focus on disproving one or more of the required statutory elements.



New York False Testimony to Harm Defendant | Challenging Materiality


If the statement was not significant to the outcome of the case, it may not qualify as material. Minor factual inaccuracies or peripheral topics often fail the materiality threshold.



New York False Testimony to Harm Defendant | Disputing Knowledge of Falsity


The prosecution must prove the person knew the statement was false. Mistaken memory, interpretation errors, or reliance on incorrect secondary information may be valid defenses.



New York False Testimony to Harm Defendant | Stressing Retraction or Cooperation


Voluntary retraction of the false statement before the judgment is entered may help in mitigating penalties. Cooperation with prosecutors may also result in leniency at sentencing.
