May pardon be granted during the pendency of an appeal?

Pardon can be granted only after conviction by final judgment. (People vs. Salle, G.R. No. 103567, December 4, 1995)

The conviction by final judgment limitation under Section 19, Article VII of the present Constitution prohibits the grant of pardon, whether full or conditional, to an accused during the pendency of his appeal from his conviction by the trial court. Any application therefor, if one is made, should not be acted upon or the process toward its grant should not be begun unless the appeal is withdrawn. Accordingly, the agencies or instrumentalities of the Government concerned must require proof from the accused that he has not appealed from his conviction or that he has withdrawn his appeal. Such proof may be in the form of a certification issued by the trial court or the appellate court, as the case may be. The acceptance of the pardon shall not operate as an abandonment or waiver of the appeal, and the release of an accused by virtue of a pardon, commutation of sentence, or parole before the withdrawal of an appeal shall render those responsible therefor administratively liable. Accordingly, those in custody of the accused must not solely rely on the pardon as a basis for the release of the accused from confinement. (People of the Philippines vs. Bacang, G.R. No. 116512, July 30, 1996)
