Case Summary (G.R. No. 46267)

Appointment History of the Petitioner

Petitioner’s original appointment (June 2, 1936) covered only the Fifth Branch, CFI Manila. After the enactment of Commonwealth Act No. 145 (Nov. 7, 1936), he accepted an ad interim appointment to the newly created Fourth Judicial District, with authority over both the Fifth Branch, Manila, and the entire province of Palawan. A second ad interim appointment followed on Nov. 22, 1937.

Performance of Judicial and Administrative Functions

Acting as executive judge under his Fourth District appointment, petitioner:
• Designated an administrative officer for Palawan affairs
• Appointed a notary public for Palawan
• Authorized justices of the peace in Palawan to defend cases or grant leaves of absence

Disapproval of Petitioner’s Appointment and Respondent’s Installation

On May 19, 1938, the Commission on Appointments disapproved petitioner’s ad interim appointment, effective upon notice on May 20. On Aug. 1, 1938, the President appointed and the Commission confirmed respondent as Judge of First Instance, Fourth Judicial District (Fifth Branch, Manila, and Palawan), followed by issuance of a final appointment the same day.

Estoppel as a Bar to Constitutional Challenge

Respondent asserted that petitioner is estopped from questioning Commonwealth Act No. 145’s constitutionality because petitioner voluntarily accepted the new appointment, qualified by oath, and discharged its duties. The Court first addressed this procedural defense.

Doctrine of Incompatibility and Abandonment of Office

The Court found the two appointments incompatible: the later Fourth District appointment expanded jurisdiction to Palawan and absorbed the prior office. By accepting the newer appointment, taking the oath, performing judicial and administrative acts, and receiving compensation, petitioner abandoned his original office.

Application of Equitable Estoppel

Under established equity and jurisprudence, a public officer who accepts an incompatible office created by statute—and enters upon its duties—abandons the former office and cannot attack the statute’s constitutionality. Exceptions (public interest or compulsion) did not apply: petitioner was free to refuse or accept with reservation. Having acted with full knowledge of possible disapproval, he may not now reclaim his former office or challenge the law’s validity.

Conclusion of the Majority

Because petitioner is estopped from questioning Commonwealth Act No. 145 and has ipso jure ceased exercising both offices after disapproval, the quo warranto petition was denied and dismissed, with costs against petitioner.
