G.R. No. 254001 - Bayyo Association, Inc. and Anselmo Perweg, in his capacity as President of the Association, vs. Secretary Arthur Tugade, et al.

Petitioner: People of the Philippines.
Respondents: Hon. Judge Mericia B. Palma (City Court of Naga) and accused Romulo Intia y Morada.

City Court of Naga vs. Juvenile and Domestic Relations Court (JDRC) for Camarines Sur over criminal cases where the accused is 16 but under 21 years old.
R.A. 6591 (effective September 30, 1972) expressly grants JDRC jurisdiction only over offenders under 16 at the time of filing.
P.D. 603 (Child and Youth Welfare Code, effective June 11, 1975) defines a “youthful offender” as one over 9 but under 21 at the time of the offense.

On February 10, 1976, Romulo Intia y Morada, age 17, was charged with vagrancy (RPC Art. 202, par. 2) in the City Court of Naga.
On March 6, 1976, Judge Palma dismissed the case for lack of jurisdiction and ordered refiling in the Juvenile Court.
The People filed a petition for certiorari and prohibition before the Supreme Court to resolve the jurisdictional issue.

Whether the definition of “youthful offender” in P.D. 603 (over 9 but under 21) transferred jurisdiction over 16–under 21 offenders from regular courts to the Juvenile Courts.
Whether a general law (P.D. 603) can impliedly repeal or expand the special and limited jurisdiction conferred by R.A. 6591 on the JDRC of Camarines Sur.
