Montserrat’s criminal justice is not unique in its jurisprudence, it is an overseas territory of the United Kingdom. What is unique is its evolution particularly since a major volcanic eruption in 1995 devastated the island. Since then how its criminal systems have adjusted to a weird and dynamic population immigration and emigration, the socio-economic effects and strange nuisances in criminal behaviour warrants some description and analysis. This paper presents as a backdrop the socio economic and criminal justice legislation of crime and punishment. Crime statistics are examined and the systems that are in place to address crime is analysed. The data is generated from interviews with current criminal justice practitioners working on the island and forms an influential model of crime post a major disaster, a phenomenon which is not a rarity in our modern global society, yet little examined in criminology.
