Nova Scotians are subject to laws set out in legislation and case law. Legislation is made be legislatures.  When a case comes to court, a judge interprets what the law means and how it applies, and these court decisions are called "case law". For example, the Canadian Charter of Rights and Freedoms says that an accused is entitled to a trial within a reasonable time. Judges have interpreted what a “reasonable time” means - the Supreme Court of Canada did so in a 2016 case called R v. Jordan.  As the Supreme Court of Canada is the highest court in Canada, the legal principles set out in the Jordan decision are law and now govern how that Charter right is to be interpreted and applied.
