Thus, even if the Court were to remand these cases to the CA for intermediate review, the CA would only be constrained to dismiss appellant’s appeal, as he is considered a fugitive from justice. On this core, Section 8, Rule 124 of the Rules of Court is relevant, which provides:
SEC. 8. Dismissal of appeal for abandonment or failure to prosecute. – The Court of Appeals may, upon motion of the appellee or motu proprio and with notice to the appellant in either case, dismiss the appeal if the
appellant fails to file his brief within the time prescribed by this Rule, except where the appellant is represented by a counsel de officio.
The Court of Appeals may also, upon motion of the appellee or motu proprio, dismiss the appeal if the appellant escapes from prison or confinement, jumps bail or flees to a foreign country during the pendency of the appeal.
(Emphasis supplied)
It bears to stress that the right to appeal is merely a statutory privilege,
and, as such, may be exercised only in the manner and in accordance with the provisions of the law. The party who seeks to avail of the same must comply with the requirements of the Rules, failing which, the right to appeal
is lost."
