Final judgment v. Interlocutory order

In Denso (Phils.), Inc. v. Intermediate Appellate Court,[1] the Supreme Court expounded on the differences between a “final judgment” and an “interlocutory order,” to wit:
x x x A “final” judgment or order is one that finally disposes of a case, leaving nothing more to be done by the Court in respect thereto, e.g., an adjudication on the merits which, on the basis of the evidence presented at the trial, declares categorically what the rights and obligations of the parties are and which party is in the right; or a judgment or order that dismisses an action on the ground, for instance, of res judicata or prescription. Once rendered, the task of the Court is ended, as far as deciding the controversy or determining the rights and liabilities of the litigants is concerned. Nothing more remains to be done by the Court except to await the parties' next move x x x and ultimately, of course, to cause the execution of the judgment once it becomes “final” or, to use the established and more distinctive term, “final and executory.”

x x x x x x x x x

Conversely, an order that does not finally dispose of the case, and does not end the Court's task of adjudicating the parties' contentions and determining their rights and liabilities as regards each other, but obviously indicates that other things remain to be done by the Court, is “interlocutory,” e.g., an order denying a motion to dismiss under Rule 16 of the Rules x x x. Unlike a “final” judgment or order, which is appealable, as above pointed out, an “interlocutory” order may not be questioned on appeal except only as part of an appeal that may eventually be taken from the final judgment rendered in the case.[2]
