Law Office of Matthew W Peterson County and Court Message

What Is Mayhem Under Massachusetts Law?

Under Massachusetts General Laws Chapter 265, Section 14, Mayhem is defined as the malicious intent to maim or disfigure another person. This includes actions such as cutting or removing someone’s tongue, eye, ear, nose, or limb, or otherwise making them permanently disabled or disfigured.

There are two types of Mayhem charges under Massachusetts law:

  1. Mayhem by specific acts – where certain forms of mutilation (cutting out a tongue, slitting a nose or lip, disabling a limb, etc.) are intentionally inflicted.

  2. Mayhem by dangerous means – where someone intentionally inflicts serious injury using a dangerous weapon or method, resulting in permanent disfigurement or disability.

The law treats Mayhem as a felony, and a conviction can result in a state prison sentence of up to 20 years. The consequences of such a charge go far beyond incarceration — a felony conviction can affect employment, housing, and many civil rights for years to come.

Why You Need a Massachusetts Defense Attorney for a Mayhem Charge

Our attorneys understand how prosecutors think, especially with our unique experience that includes a former prosecutor on our team. This allows us to anticipate how your case will be pursued and identify weaknesses in the state’s argument.

Potential Defenses to a Mayhem Charge

Every case is unique, but potential defenses in a Mayhem case may include:

  • Lack of Intent: Mayhem requires intentional conduct. If the injury occurred accidentally or without malice, this could reduce or dismiss the charge.
  • Self-Defense: If the injury occurred while defending yourself or another person from harm, this may be a valid defense.
  • False Accusations: Sometimes, accusations are exaggerated or completely fabricated. This can be exposed through cross-examination and investigation.
  • Insufficient Evidence: Prosecutors must prove every element of the crime beyond a reasonable doubt. We ensure they are held to that high standard.


Our approach focuses on examining every aspect of your case and tailoring a strategy to your specific circumstances. This includes reviewing medical records, witness statements, and police reports to uncover facts that support your defense.

Frequently Asked Questions

Is Mayhem a felony in Massachusetts?

Yes. Under Massachusetts law, Mayhem is classified as a felony offense punishable by up to 20 years in state prison.

Assault may involve threats or attempts to cause harm, while Mayhem requires intentional and permanent disfigurement or disablement of another person.

In some cases, charges may be reduced to assault or assault and battery if evidence of intent or permanent injury is lacking. An experienced defense attorney can help pursue this outcome.

Accidental injuries generally do not qualify as Mayhem. Intent is a required element of the offense, and proving the injury was unintentional may be a key defense strategy.

It depends on where the incident occurred. Cases may be prosecuted in District or Superior Court, typically in the county where the alleged offense happened.
