This report, titled Law of the Tiger, provides a comprehensive 2025 analysis of the legal frameworks governing tiger trafficking across twelve range states. It evaluates how national laws address critical issues such as interagency enforcement, mandatory confiscation, and the regulation of captive breeding facilities. The authors identify significant legal gaps regarding digital marketplaces, the status of hybrid tigers, and the management of confiscated stockpiles. To combat the transnational organized crime of wildlife trade, the document advocates for standardized definitions, enhanced investigative powers for frontline officers, and the integration of anti-money laundering tools. Ultimately, the publication serves as a guide for governments to harmonize their criminal justice responses and strengthen protections for wild tiger populations.
