Massachusetts has a Dead man's act. Mass.Gen.L. c. 233, § 65. This isn't as scary as it may sound. This law relates to use of statements of a dead person in a court proceeding. It is part of a rule of evidence known as the hearsay rule.
There are a number of dead body laws. If a person removes or disinters a dead body they can be punished by up to three years in the state prison. Mass.Gen.L. c. 272, § 71. It is illegal to sell a dead body or body parts and is punishable by up to two a half years in jail. Mass.Gen.L. c. 272, § 72. Sheriffs and constables are prohibited from seizing a dead body to collect a debt. If they do, they can be punished by six months in jail. Mass.Gen.L. c. 272, § 70. (How does a sheriff collect a debt by seizing a dead body?)
In California witches need to be licensed. In re Zsuzsanna Bartha 63 Cal.App.3d 584, 134 Cal.Rptr 39, 91 A.L.R.3rd 759 (l976). Massachusetts, home of Salem witchcraft, does not license witches. Our history involving witches resulted in a change in rules of evidence. During the witchcraft trials in the early 1690s, spectoral evidence was allowed in courts. Spectoral evidence was a person testifying that they saw a ghost or other supernatural creature or event. Nineteen people were executed based on such evidence. Massachusetts prohibited the use of spectoral evidence around the middle 1690s and hasn't convicted a witch since.
In 1991, a New York Court found facts to determine that a house was haunted. Stambovsky v. Ackley, 169 A.D.2d 254 (NY App. Div. 1991). The court reached this conclusion based in part on evidence that was spectoral in nature.
In the United States, you can't sue the Devil. Someone actually tried that. In U. S. ex rel. Mayo v. Satan and his Staff, 54 F.R.D. 282 (W.D. Pa. 1971) the court dismissed a lawsuit against Satan because as the principality of his own kingdom, he is beyond the jurisdiction of the courts.
It appears that necrophilia is not a crime in Massachusetts. In the case of Commonwealth v. Costa, 360 Mass. 177 (1971), it appears that there sufficient facts to prosecute for necrophilia but the Commonwealth didn't prosecute for that. While necrophilia may not be a crime, rememeber, you can't move the body. It appears that necrophilia doesn't constitute adultry either. Good thing we have no fault divorce for anybody who discovers that their spouse engages in necrophilia.
It wouldn't be Halloween without trick or treating. If tricks involve damage to property, that constitutes the crime of vandalism. Mass.Gen.L. c. 266, §§ 94-107. If the trick involves a john then the “trick” is prostitution and is illegal. Mass.Gen.L. c. 272, §§ 53, 53A.
For many people, Halloween means parties. Parties, at any time of year, have the potential for legal problems. It is a crime to serve alcohol to minors. Mass.Gen.L. c. 138, § 34. If a person drinks too much at a party and then drives and has an accident, the host of the party can be sued for the resulting injuries. This is known as social host liability and exists in Massachusetts. Most towns have ordinances that prohibit parties from making too much noise late at night. Usually police give a warning when they first arrive at the home where a noisy party exits. However, they may have the power to arrest for the offense of making noise late at night.
Halloween celebrating can result in some people drinking and driving. Massachusetts prohibits operating a motor vehicle under the influence of alcohol. Mass.Gen.L. c. 90, § 24.
Halloween should be a time for fun. Have a happy Halloween and make sure you don't move any dead bodies, do any illegal tricks, or party too hard. If you do any of these things, you may have to hire a lawyer which could be scarier than any costumed person who shows up at your door.
