G.R. No. L-9282; February 13, 1915
THE UNITED STATES, plaintiff-appellant, vs. AGUSTIN CLAVERIA, defendant-appellee.

FACTS:
An information was filed against Agustin Claveria. In the lower court, the defendant raised the defense that he had already been tried and convicted for the same crime, placing him in double jeopardy. The trial court sustained this defense and dismissed the information. The Attorney-General appealed the dismissal, arguing that the defense of double jeopardy or former conviction is not a proper ground for a demurrer under General Orders No. 58 (the then governing procedural rules) but is a matter that must be pleaded and proven as a defense during trial.

Upon review, the Supreme Court found that the proceedings in the lower court were mischaracterized. The record indicated that the defendant did not file a demurrer. Instead, after arraignment, he entered an oral plea of “autrefois convict” (a former judgment of conviction) based on a prior case tried in the same court just two days earlier. The trial judge based his dismissal on this plea, with the record of the prior conviction being considered, either by reference or actual production, during the proceeding without objection from the parties.

ISSUE:
Whether the trial court erred in dismissing the information based on the defendant’s plea of former conviction, and whether the Attorney-General’s appeal on the procedural ground that such a defense cannot be raised via demurrer is meritorious.

RULING:
The Supreme Court DISMISSED the appeal. The Court held that the proceedings below were not based on a demurrer but on a proper oral plea of a former judgment of conviction, which is expressly allowed under Sections 24 and 25 of General Orders No. 58. The plea could be entered with or without a plea of not guilty. The Court found that the record of the prior case was properly before the trial court during the plea proceedings, either by physical submission or by reference without objection, and it constituted competent evidence to support the plea. Since the Attorney-General’s appeal was premised solely on the erroneous assumption that the dismissal was based on a demurrer, and this ground was not supported by the record, the appeal was without merit. The Court expressly reserved its opinion on the substantive merits of the double jeopardy claim and on the general right of the government to appeal such a dismissal, as these issues were not raised in the appeal.
