Judicial notice is a legal concept that allows a court to accept certain facts as true without the need for any evidence to be presented. Judicial notice can be taken of matters of general knowledge, matters that are so notorious to be judicially noticed, and matters that are of public record. There are two types of judicial notice: mandatory and discretionary. Mandatory judicial notice requires the court to accept certain matters as true, while discretionary judicial notice allows the court to accept or reject evidence as true or not true on a case-by-case basis.
