While it is true that some of the documents required by this Court to be submitted by the parties were not presented at the trial stage, when the legal issues raised begs the reception of that evidence – especially considering that a case, like the present one  has been pending for more than a decade – then the Court may require the parties to submit such evidence in the interest of justice.  This is clearly provided under Rule 45, Section 7 of the Rules of Court.[38]
