Polygamy per se can be viewed differently. If only one marriage is registered and the subsequent marriages are only religious or common law marriages, some nations do not regard polygamy as bigamy, since only one marriage is accepted as legal.
In the US, the law regards religious/common law marriages differently in different states. In some states, like say New Jersey, polygamy is not always illegal since a nikah or a common law marriage is not accepted by law. A second wife hence is not regarded as a wife, she’s just a sideshow.
If however a polygamist in states like New Jersey were a member of the Armed Forces, the situation would be completely different. Such a person, say e.g. an officer in the Armed Services, would be subject to military law. According to the law of the US Armed Forces, not only is bigamy illegal but also the attempt to commit bigamy. Hence, a polygamist who is only religiously married to a second wife, not legally, can still be convicted of attempt. I refer you to the law, you can find it here. As you can see, the law also considers whether the crime committed means that the conduct of the accused was to the prejudice of good order and discipline in the armed forces or was of a nature to bring discredit upon the armed forces. Matters to consider here could be e.g. if the crime was committed in public, e.g. described on a blog. If testimony shows that the crime was committed in a disgraceful way, e.g. causing extended pain and suffering or e.g. was directed at the rights of women while the subordinates of an officer committing the crime were dying in Afghanistan while defending the rights of women, such matters would be considered.
Furthermore, according to martial law, adultery is also a crime. The law says adultery is a crime and must be punished if it can be proven:
- 1) That the accused wrongfully had sexual intercourse with a certain person;
- (2) That, at the time, the accused or the other person was married to someone else; and
- (3) That, under the circumstances, the conduct of the accused was to the prejudice of good order and discipline in the armed forces or was of a nature to bring discredit upon the armed forces.
This means that the punishment would be severe if e.g. facts show that the crime was committed in a disgraceful way, e.g. causing extended pain and suffering or e.g. was directed at the rights of women, while the subordinates of an officer committing the crime were dying in Afghanistan while defending the rights of women. Proof, such as a deleted blog, can easily be obtained by the authorities.
Since polygyny is a crime against humanity and a vile offense against human rights, we who believe in human rights and the law should certainly report all such crimes.
If anybody should know of such a crime, it should be reported to the Armed Forces, primarily, not the police.
If the suspect was in e.g. the National Guard, the correct place to make such a report would be directly to the National Guard, in the case of New Jersey e.g. here.
Since the governor is the head of the National Guard, one should also report the crime to his office, in the case of New Jersey e.g. here.
A convicted polygamist would lose all pensions and benefits.
