Judicial Notice is a legal concept in which a court or judge can recognize certain facts as true, without requiring any proof from the parties. It is the duty of the court to take judicial notice of matters that are generally known or capable of accurate and ready determination by resort to sources whose accuracy cannot reasonably be questioned. There are two types of Judicial Notice: mandatory judicial notice and discretionary judicial notice. Mandatory Judicial Notice requires that a court take judicial notice of certain facts, such as the laws of a state or the decisions of prior courts. Discretionary Judicial Notice allows a court to take judicial notice of certain facts, but it is not required by law. Both types of judicial notice are based on the assumption that certain facts are so well-known or easily verifiable that they do not need to be proven.
