Most countries do not have any law which governs the usage of Body Armor. Body Armor is usually legal to use in most countries with a few exceptions. One of the notable exceptions is Australia. Use of Body Armor has been banned in Australia and use of any kind of Body Armor is illegal and a punishable offence under the Australian laws. This prohibition has been continuing for quite some times. There are stores floating around about the history of this ban when in the late 19th century the very notorious outlaw called Ned Kelly used home made Body Armor with some mixed results. The police at that time were using the Martini-Henry rifles which used low velocity, soft lead bullets. The home made Body Armor of Ned Kelly practically defeated these bullets. Though the steel Body Armor was successful against the bullets, the weight restricted the movements and ultimately led to his downfall. It is said that since then the Australian law has banned the use of Body Armor.

The Unites States allows the used of Body Armor legally by any one except by those who have been convicted of violent felony. Most of the US states have heavy penalties for use of Body Armor by convicted felons. Even possession of Body Armor by convicted felon is not allowed.
