Penal Code CAP 26 (Act No. 12 of 1963).

The Penal Code is the primary source of criminal law in the Solomon Islands. It defines criminal offenses, categorizes them (such as felonies and misdemeanors), establishes the jurisdiction of the courts, and sets the penalties for prohibited conduct. It is organized into several parts, beginning with Part I (Preliminary) and Part II (Interpretation), followed by Part III (Territorial Application) and Part IV (General Rules as to Criminal Responsibility), which sets out principles such as intent, mistake, and insanity. Subsequent parts address Part V (Parties to Offences) and Part VI (Punishments), while later sections cover specific categories of offences such as offences against public order, offences affecting external relations, and a wide range of crimes against persons and property, reflecting a structured and comprehensive codification of criminal conduct.
The Code criminalizes several acts relevant to environmental protection, property, and natural resources. These include offences related to property rights and larceny, covering the unlawful taking of items such as trees, fruits, vegetables, and oysters, as well as broader theft-related offences. It also addresses offences involving damage to animals, unlawful use of animals, and killing animals with intent to sell, as well as acts that harm agricultural and ecological resources, such as setting fire to crops, growing plants, or cultivated produce (including arson-related offences). Additional provisions cover communicating infectious diseases to animals, reflecting concern for livestock and animal health, and other harmful acts affecting environmental resources. While the Penal Code itself focuses primarily on general criminal offences, related conduct such as water and air pollution, forest fires, and broader environmental harm may also intersect with offences like nuisance, property damage, or public safety violations. It also includes offences relating to corruption and abuse of office, ensuring accountability in the exercise of public authority.
