While statute of limitations cases typically begin when an injury occurred, there are exceptions such as the “discovery rule.” This rule applies in situations in which an injured party couldn’t have reasonably discovered their injuries immediately following them occurring.
Suppose someone undergoes surgery and inadvertently left a surgical tool inside them; complications could emerge months or even years later before realizing what had happened, prompting the statute of limitations to begin on either the date the injury was discovered or should have been discovered.
