Massachusetts Perjury Laws and Consequences

A crime against justice doesn't inflict personal harm like an assault or damage belongings like property crimes. However, these crimes are still very harmful because they corrupt the judicial system and interfere with the administration of justice. Examples of crimes against justice include witness tampering, withholding evidence, and the offense of perjury which involves making false statements or lying under oath.

Acts that Constitute Perjury in Massachusetts

In Massachusetts, perjury is committed when an individual:

1. Intentionally gives false testimony in a judicial proceeding; or
2. Deliberately gives a false statement while they're under oath.

Subornation of Perjury

If an individual incites or attempts to get another person to commit perjury, then they can be charged with subornation of perjury. A person can be guilty of this offense even if the other person didn't in fact commit perjury.
