Sandigan ignored probes

I AM just wondering why the Sandiganbayan, in its resolution on the plea bargain agreement, completely ignored and totally disregarded the congressional investigations conducted by both the Senate and the House of Representatives.
Under Section 1 of Rule 129 of the Rules on Evidence, the Sandiganbayan should have taken judicial notice of the Senate and House investigations (which need not be proved). Had it done so in an honest-to-goodness manner or had the Office of the Ombudsman called the Sandiganbayan’s attention regarding the existence of Rule 129, it would have been egregiously unconscionable for the Court to approve the plea bargain agreement with Gen. Carlos Garcia.
Section 1, Rule 129 states: “Judicial notice, when mandatory. —A court shall take judicial notice, without the introduction of evidence, of the existence and territorial extent of states, their political history, forms of government and symbols of nationality, the law of nations, the admiralty and maritime courts of the world and their seals, the political constitution and history of the Philippines, the official acts of legislative, executive and judicial departments of the Philippines, the laws of nature, the measure of time, and the geographical divisions.”
