G.R. No. L-4662 - People vs. Castelo

The People of the Philippines filed a criminal case (No. 10923) in the Court of First Instance of Manila for malversation of public property.
The accused in the case were Eduardo Castillo, Pedro R. Pena, Gregorio E. Pura, and Pablo Malasarte.

On February 17, 1951, during trial proceedings, the prosecution petitioned to introduce material witnesses (notably Mrs. Enriqueta V. Pascual, among others) to establish as direct evidence certain admissions or confessions made by the defendants during their preliminary investigation by the City Fiscal of Manila.
The petition was based on showing that the defendants had made incriminating statements during the preliminary investigation conducted under oath by the City Fiscal or his assistant.

On March 2, 1951, the Court of First Instance of Manila denied the petition to admit the statements.
The denial was grounded on:

Section 38 of Republic Act No. 409 (Revised Charter of the City of Manila), which did not contain the explicit provision previously found in Chapter 60 of the Revised Administrative Code.
The argument that declarations made during a preliminary investigation were considered privileged and, therefore, inadmissible.

Under the Revised Administrative Code, Section 2465—as amended by Commonwealth Act No. 537—testimony elicited under oath by the City Fiscal was originally barred from being used against the witness in any prosecution.
Republic Act No. 409, approved on June 18, 1949, repealed Chapter 60 of the Revised Administrative Code. Consequently, the protection previously granted under Section 2465 was removed, thereby permitting the use of testimonials from the preliminary investigation as evidence.

Respondents argued that allowing the use of these statements would effectively compel an accused to be a witness against himself, thus violating constitutional protections against self-incrimination.
The petitioner, however, maintained that:

The confessions or admissions were made voluntarily.
Precedents, such as People vs. Carillo, and the universal acceptance of voluntary confessions, reinforce the admissibility of such evidence, even if elicited during a preliminary investigation.

Whether the confessions or admissions made by the defendants during the preliminary investigation conducted by the City Fiscal of Manila are admissible as direct evidence in the criminal prosecution.
Whether the repeal of the statutory prohibition (originally contained in Section 2465 of the Revised Administrative Code) by Republic Act No. 409 permits the use of such statements.

Whether the use of these confessions would violate the constitutional protection against self-incrimination by effectively forcing an accused to be a witness against himself.
Whether the voluntary nature of the confessions removes the concern of compelled self-incrimination, as argued by the respondents.
