Preliminary Investigation in Criminal Cases

At the outset, let’s remove any possibility of misunderstanding that may be caused by the title of this post. The reference to a “preliminary investigation in criminal cases” does not imply that there’s a preliminary investigation in civil cases – there’s none. Preliminary investigation is a part of the rules of criminal procedure. Simply stated, it’s available ONLY in criminal cases.

1. What is Preliminary Investigation?

Preliminary investigation is an inquiry or proceeding to determine whether there is sufficient ground to engender a well-founded belief that a crime has been committed and the respondent is probably guilty thereof, and should be held for trial.

2. What is the Nature and Purpose of preliminary investigation?

The determination of probable cause during a preliminary investigation is an executive function, the correctness of the exercise of which is a matter that the trial court itself does not and may not be compelled to pass upon.

In a preliminary investigation, the investigating prosecutor makes a determination if there’s a probable cause, which is the existence of such facts and circumstances as would excite the belief, in a reasonable mind, acting on the facts within the knowledge of the prosecutor, that the person charged was guilty of the crime for which he was prosecuted. It has been explained as a reasonable presumption that a matter is, or may be, well founded, such a state of facts in the mind of the prosecutor as would lead a person of ordinary caution and prudence to believe, or entertain an honest or strong suspicion, that a thing is so. The term does not mean “actual and positive cause” nor does it import absolute certainty. It is merely based on opinion and reasonable belief. Thus, a finding of probable cause does not require an inquiry into whether there is sufficient evidence to procure a conviction. It is enough that it is believed that the act or omission complained of constitutes the offense charged, as there is a trial for the reception of evidence of the prosecution in support of the charge.

The purpose of a preliminary investigation is to secure the innocent against hasty, malicious and oppressive prosecution, and to protect him from an open and public accusation of a crime, from the trouble, expense and anxiety of a public trial, and also to protect the state from useless and expensive trials. A preliminary investigation serves not only the purposes of the State. More important, it is a part of the guarantees of freedom and fair play which are birthrights of all who live in our country. It is therefore, imperative upon the fiscal or the judge as the case may be, to relieve the accused from the pain of going through a trial once it is ascertained that the evidence is insufficient to sustain a prima facie case or that no probable cause exists to form a sufficient belief as to the guilt of the accused. The judge or fiscal, therefore, should not go on with the prosecution in the hope that some credible evidence might later turn up during trial for this would be in flagrant violation of a basic right which the courts are created to uphold. (Salonga vs. Cruz Paño)

3. When is preliminary investigation required?

A preliminary investigation is required to be conducted before the filing of a complaint or information for an offense where the penalty prescribed by law is at least four (4) years, two (2) months and one (1) day, without regard to the fine.

A preliminary investigation is not required in cases of “warrantless arrests.” When a person is lawfully arrested without a warrant involving an offense which requires a preliminary investigation, the complaint or information may be filed by a prosecutor without need of such investigation provided an inquest has been conducted in accordance with existing rules. However, after the filing of the complaint or information in court without a preliminary investigation, the accused may, within five (5) days from the time he learns of its filing, ask for a preliminary investigation.

4. Who are the officers authorized to conduct preliminary investigations?

The following may conduct preliminary investigations:

(a) Provincial or City Prosecutors and their assistants;
(b) Judges of the Municipal Trial Courts and Municipal Circuit Trial Courts;
(c) National and Regional State Prosecutors; and
(d) Other officers as may be authorized by law.

5. What are the basic steps in preliminary investigation?

The basic steps (further discussed in the subsequent paragraphs) in preliminary investigation are:

1. Filing of the Complaint-Affidavit.
2. Issuance of subpoena by the investigating prosecutor to the respondent.
3. Filing of Counter-Affidavit by the respondent.
4. If allowed by the prosecutor, filing of Reply-Affidavit (by the complainant) and Rejoinder-Affidavit (by the respondent).
5. Resolution.

6. What are the requirements in filing the Complaint-Affidavit?

The complaint shall state the address of the respondent and shall be accompanied by the affidavits of the complainant and his witnesses, as well as other supporting documents to establish probable cause. They shall be in such number of copies as there are respondents, plus two (2) copies for the official file. The affidavits shall be subscribed and sworn to before any prosecutor or government official authorized to administer oath, or, in their absence or unavailability, before a notary public, each of whom must certify that he personally examined the affiants and that he is satisfied that they voluntarily executed and understood their affidavits.

The complaint is also generally required to pay filing fees.

7. What actions are taken by the investigating prosecutor after the complaint is raffled to him/her?

Within ten (10) days after the filing of the complaint, the investigating officer shall either dismiss it if he finds no ground to continue with the investigation, or issue a subpoena to the respondent attaching to it a copy of the complaint and its supporting affidavits and documents.

I haven’t encountered any case where the investigating prosecutor dismissed the case prior to the issuance of the subpoena. Moreover, in practice, the complaint and the annexes are not usually attached to the subpoena, but are provided to the respondent during the initial stage.

8. How is the Counter-Affidavit submitted by the respondent?

Within ten (10) days from receipt of the subpoena with the complaint and supporting affidavits and documents, the respondent shall submit his counter-affidavit and that of his witnesses and other supporting documents relied upon for his defense. The counter-affidavits shall be subscribed and sworn to and certified before the investigating prosecutor (which means that the respondent must generally be present during the submission of the counter-affidavit), with copies furnished to the complainant. The respondent is not be allowed to file a motion to dismiss in lieu of a counter-affidavit.

9. Can the investigating prosecutor resolve the complaint if the respondent does not appear?

Yes. If the respondent cannot be subpoenaed, or if subpoenaed, does not submit counter-affidavits, the investigating office shall resolve the complaint based on the evidence presented by the complainant. Within ten (10) days after the investigation, the investigating officer shall determine whether or not there is sufficient ground to hold the respondent for trial.

This is the reason why, even in cases where a preliminary investigation is required, it’s entrely possible that a warrant of arrest may be isued without the respondent/accused being informed about or having participated in a preliminary investigation. So, don’t disregard a subpoena in a preliminary investigation.

10. How is the resolution prepared?

If the investigating prosecutor finds cause to hold the respondent for trial, he shall prepare the resolution and information. He shall certify under oath in the information that he, or as shown by the record, an authorized officer, has personally examined the complainant and his witnesses; that there is reasonable ground to believe that a crime has been committed and that the accused is probably guilty thereof; that the accused was informed of the complaint and of the evidence submitted against him; and that he was given an opportunity to submit controverting evidence. Otherwise, he shall recommend the dismissal of the complaint.

Within five (5) days from his resolution, he shall forward the record of the case to the provincial or city prosecutor or chief state prosecutor, or to the Ombudsman or his deputy in cases of offenses cognizable by the Sandiganbayan in the exercise of its original jurisdiction. They shall act on the resolution within ten (10) days from their receipt thereof and shall immediately inform the parties of such action.

11. Can the Information be filed without the written authority of the proper authorities?

No complaint or information may be filed or dismissed by an investigating prosecutor without the prior written authority or approval of the provincial or city prosecutor or chief state prosecutor or the Ombudsman or his deputy.

Where the investigating prosecutor recommends the dismissal of the complaint but his recommendation is disapproved by the provincial or city prosecutor or chief state prosecutor or the Ombudsman or his deputy on the ground that a probable cause exists, the latter may, by himself, file the information against the respondent, or direct another assistant prosecutor or state prosecutor to do so without conducting another preliminary investigation.

An Information filed in court may be quashed, among other reasons, if it does not contain the approval or authority of the aforementioned superiors.

12. What is the procedure if the preliminary investigation is conducted by a judge?

The procedure is basically the same as described above. Within ten (10) days after the preliminary investigation, the investigating judge shall transmit the resolution of the case to the provincial or city prosecutor, or to the Ombudsman or his deputy in cases of offenses cognizable by the Sandiganbayan in the exercise of its original jurisdiction, for appropriate action. The resolution shall state the findings of facts and the law supporting his action, together with the record of the case which shall include: (a) the warrant, if the arrest is by virtue of a warrant; (b) the affidavits, counter-affidavits and other supporting evidence of the parties; (c) the undertaking or bail of the accused and the order for his release; (d) the transcripts of the proceedings during the preliminary investigation; and (e) the order of cancellation of his bail bond, if the resolution is for the dismissal of the complaint.

Within thirty (30) days from receipt of the records, the provincial or city prosecutor, or the Ombudsman or his deputy, as the case may be, shall review the resolution of the investigating judge on the existence of probable cause. Their ruling shall expressly and clearly state the facts and the law on which it is based and the parties shall be furnished with copies thereof. They shall order the release of an accused who is detained if no probable cause is found against him.

    Good Day!

    Want to ask a question. Can I file a motion to reopen and submit additional evidence in a case which is under preliminary investigation by DOJ prosecutor. The case was submitted for resolution 15 days ago. I want to file this motion because I recently found evidence which I think is crucial to the result of the investigation. Thanks.

    Hi Atty.,

    I have a concern on how to clear my name with the civil case already settled.

    I was complained by a lending company way back 2014 for not paying my debt but we agreed to a certain amount that I have to pay for 2 months and I paid it in full on the given due date.

    I thought my records will be automatically cleared but when I applied for a furniture loan recently, they told me I still have an unsettled loan in a lending company. And even my co-maker has still pending charges on record.

    I visited the lending company and they have given me a certificate stating my account was already settled.

    My problem now is how can my name be cleared in the court and in the “credit organization” ?(not sure of the org’s name)

    Waiting for your reply.

    Thank you!

    If the re-joinder was filed by both accused and their witness, does it follow that all three has a collaborated statement? If so, when one of the accused has witness in court and found to be guilty of the offense does it follow that same verdict shall be given to the other accused and nullify the statementment of the witness for having the same collaborated story/defense?
