In depth
Stare decisis (Latin for 'to stand by things decided') is the legal principle that courts should follow prior decisions (precedents) when deciding similar cases. It promotes consistency and predictability in the law.
For CBD cases, stare decisis is important because: (1) the Italian Cassazione's 2009 ruling on 1948 cases established a precedent that lower courts now follow, (2) the German BVA's prior decisions on Article 116 cases guide future decisions, and (3) the Canadian Federal Court's rulings on Lost Canadian cases shaped the legislative response (Bill C-71).
However, stare decisis is not absolute — courts can overturn their own precedents (as the Cassazione did in 2009) and legislatures can override judicial decisions by statute. CBD law continues to evolve through both judicial and legislative action.
