G.R. No. L-17398 - Lacsosn vs. Villafranca

In March 1958, following the retirement of the incumbent Deputy Clerk of the Municipal Court of Manila, the Secretary of Justice appointed Santos Villafranca to the vacant position.
Villafranca’s appointment was based on merit and seniority; he had several years of service in the Municipal Court with an efficiency rating of 90%.
The promotional appointment increased his salary from ₱2,700 to ₱3,600 per annum, and was made on the recommendation of the Executive Judge of the Municipal Court and approved by the Commissioner of Civil Service.

On January 27, 1959, the Mayor of Manila appointed Conrado Aquino to the same office, with the consent of the Municipal Board.
When Aquino reported for duty, the Executive Judge of the Municipal Court refused to accept him on the grounds that the position was already occupied by Villafranca.

On or about September 8, 1959, Aquino, along with the Mayor of Manila, instituted an action for quo warranto and mandamus against:

The objective of the action was to have Villafranca ousted from the office and to obtain a declaration that Aquino is the legally entitled holder of the office, including an order directing the Municipal Court’s Executive Judge to recognize Aquino as the Deputy Clerk.
The petitioners (Aquino and the Mayor) contended that the power to fill the office of Deputy Clerk was vested in the Mayor of Manila, not in the Secretary of Justice, citing provisions in Republic Act No. 409, specifically Section 22 in relation to Section 11.

The Court of First Instance of Manila ruled in favor of petitioner Aquino, sustaining the contention that the appointment power lies with the Mayor.
On the basis of this decision, appellant respondents (Villafranca, the Executive Judge, and the Secretary of Justice) appealed by certiorari, raising questions of law regarding the proper authority to appoint the Deputy Clerk.

In whom is the power to appoint the Deputy Clerk of the Municipal Court of Manila vested: the Secretary of Justice or the Mayor of Manila?

Whether the Deputy Clerk of the Municipal Court is considered an officer or employee of the City of Manila as contemplated by Republic Act No. 409, specifically under Sections 22 and 11.
Whether the Municipal Court of Manila, as an institution, falls under the administrative control of the Mayor or under that of the Department of Justice.
The propriety of the Mayor of Manila being included as a petitioner in an action for quo warranto concerning an appointive office, given that such actions are typically brought by the claimant or by the Solicitor General or fiscal.
