I think it is fairly well settled and not a matter of argument that a court will take judicial notice of its records and proceedings. In respect of the valid judgments of a court of Record, the court will readily take judicial notice of its judgments reported and unreported. I would not draw any distinction between panels of the same court. A decision of one panel is a decision of the Court and each Panel will take judicial notice of it. In my view, it is only for convenience that published report of valid judgments of court or copies of its unreported judgments are brought before a court. They need not be, they could just be cited.
