Once a complete referral reaches the inquest prosecutor, current Department of Justice rules require the inquest itself to be resolved within the day and forwarded for approval the next working day. The clock that really controls how long someone can be held beforehand is Article 125 of the Revised Penal Code: police must turn a warrantlessly-arrested person over for inquest within twelve, eighteen, or thirty-six hours, depending on the penalty for the offense, or release them.
Inquest is the fast-track proceeding used when someone is arrested without a warrant. Instead of the weeks-long preliminary investigation used for cases filed by complaint, an inquest prosecutor makes a quick, provisional call on whether the warrantless arrest was valid and whether there is enough evidence to charge the person in court — all while a constitutional and statutory clock is running against the government.
What Inquest Is and When It Applies
Inquest applies only to persons lawfully arrested without a warrant for an offense that would normally require a preliminary investigation. It is, in the words of the current Department of Justice rules, “an informal and summary investigation conducted by a prosecutor… for the purpose of determining whether said persons should remain under custody and correspondingly be charged in court.” It is not a trial, and it is not the full-blown preliminary investigation used when a complaint is filed against someone who is not under arrest.
The Article 125 Clock: 12, 18, or 36 Hours
The timeframe that actually limits how long a person can be detained before inquest concludes (or the person is released, or a preliminary investigation is instead pursued with a waiver) comes from Article 125 of the Revised Penal Code, as amended by Executive Order No. 272. A public officer who detains a person on legal grounds must deliver that person to the proper judicial authorities within:
- Twelve (12) hours — for crimes or offenses punishable by light penalties, or their equivalent;
- Eighteen (18) hours — for crimes or offenses punishable by correctional penalties, or their equivalent; and
- Thirty-six (36) hours — for crimes or offenses punishable by afflictive or capital penalties, or their equivalent.
These periods run from the time of arrest. In practice, they set the window within which the arresting law enforcement agency (or the private citizen who made a citizen's arrest) must bring the referral letter and supporting evidence to the prosecution office for inquest. The detained person must also be informed of the cause of detention and, upon request, be allowed to communicate and confer with counsel at any time.
How Long the Inquest Evaluation Itself Takes
Once the referral is complete and docketed, the actual inquest evaluation moves quickly. Under the 2024 DOJ-National Prosecution Service Rules on Preliminary Investigations and Inquest Proceedings, which took effect in 2024, inquest referrals shall be resolved within the day they are assigned to an inquest prosecutor, with the resolution transmitted to the head of the prosecution office for approval on the next working day. In other words, the DOJ's own internal target is same-day disposition of the inquest itself, distinct from — and much shorter than — the Article 125 window within which the person must first be brought to inquest.
The inquest proceeding itself typically involves the prosecutor reviewing the referral letter, affidavit of arrest, investigation report, and any complaint- or judicial affidavits; provisionally assessing whether the warrantless arrest was valid; checking that the evidence is complete; and, where necessary, asking clarificatory questions of the arresting officers, the complainant, or the detainee. Counsel for the arrested person is required to be present and to have received the referral and its attachments.
What Happens If the Referral Is Incomplete or Late
If the evidence submitted with the referral is incomplete, the referring law enforcement agency (or the private citizen who made the arrest) is required to submit what is missing — but still within the applicable Article 125 period. If the required evidence is not submitted within that period, current rules direct that the arrested person be ordered released, with the records returned to the referring agency (or, for a citizen's arrest, referred to the nearest law enforcement agency with jurisdiction) for possible refiling. If the prosecution office determines the warrantless arrest itself was invalid, release is likewise ordered.
The Option to Waive Article 125 and Undergo Preliminary Investigation
An arrested person is not required to accept inquest disposition. The inquest prosecutor must explain the nature of the proceedings and the person's option to instead avail of a regular preliminary investigation. Choosing that route means signing, in the presence of counsel, a waiver of the protections of Article 125 — effectively agreeing to remain in custody a while longer in exchange for a fuller investigation. Even with that waiver, the person may still apply for bail, and the resulting investigation must be terminated within fifteen (15) calendar days from its inception. Most people who are confident the evidence against them is weak, or who need more time to gather counter-evidence, choose this route rather than accept an immediate inquest resolution.
Step by Step: What Happens During Inquest
- Step 1. The arresting agency or citizen files a referral letter with supporting evidence at the prosecution office's docket section, within the applicable 12/18/36-hour Article 125 period.
- Step 2. The head of the prosecution office (or a designated prosecutor) provisionally checks the validity of the arrest and the completeness of the evidence.
- Step 3. If complete, the case is docketed and assigned to an inquest prosecutor, who evaluates it — typically the same day.
- Step 4. The detainee, through counsel, is informed of the charges and of the option to undergo a regular preliminary investigation instead, with a waiver of Article 125.
- Step 5. The inquest prosecutor either files an information in court (if there is prima facie evidence with reasonable certainty of conviction) or orders the person released.
Rights of the Person Under Inquest
Throughout the period leading up to and during inquest, a detained person retains a specific set of rights that arresting officers and the inquest prosecutor are bound to respect. The detainee must be informed of the cause of the detention and of the right to remain silent and to have competent and independent counsel, preferably of their own choice; if counsel cannot be afforded, one must be provided. Any waiver of these rights — including the waiver of the Article 125 protections discussed above — is valid only if made in writing and in the presence of counsel. The detainee, or counsel on their behalf, is also generally allowed to examine the referral documents before the inquest prosecutor rules on the case, so that any inconsistency in the arresting officers' account can be raised at the earliest opportunity.
For offenses that are bailable as a matter of right — that is, anything not punishable by reclusion perpetua, life imprisonment, or death — the detained person may apply for and post bail even before the inquest is concluded, and in many stations this is processed alongside the inquest referral itself. This is separate from the waiver of Article 125 described above: applying for bail on a bailable offense does not require giving up the right to be released if the case is not filed within the applicable period.
Liability for Violating the Article 125 Period
A public officer who detains a person beyond the applicable twelve, eighteen, or thirty-six hour period without delivering them to the proper judicial authorities can face criminal liability for arbitrary detention under the Revised Penal Code, in addition to any administrative liability under civil service rules. This exposure is part of why the referral packet — the affidavit of arrest, the booking sheet, and the supporting evidence — is typically assembled and brought to the prosecution office well ahead of the deadline, rather than at the last hour.
Why the Distinction Matters
People often conflate “how long can I be held” with “how long does the inquest itself take.” They are two different clocks. The 12/18/36-hour Article 125 period is about how quickly the police must hand the case over for evaluation; failing that period is itself a possible criminal liability for the detaining officer and a ground for the detainee's release. The same-day inquest-resolution rule, by contrast, governs how quickly the prosecutor must act once the case is properly before them. A family trying to help a detained relative should track both: confirm when the arrest actually happened to calculate the Article 125 deadline, and separately follow up with the inquest prosecutor's office on the status of the referral once it has been filed.
Frequently Asked Questions
How many hours can police hold someone before inquest? Twelve, eighteen, or thirty-six hours from arrest, depending on whether the offense is punishable by light, correctional, or afflictive/capital penalties, under Article 125 of the Revised Penal Code as amended by Executive Order No. 272.
Does the inquest prosecutor take days to decide? Not usually. Current DOJ rules direct that a complete inquest referral be resolved within the day it is assigned, with the resolution forwarded for approval on the next working day.
Can a person under inquest ask for a full preliminary investigation instead? Yes, but only by signing a waiver of the Article 125 protections in the presence of counsel; the person may still apply for bail, and the investigation must then be finished within fifteen calendar days.
What happens if the Article 125 period expires before the person is brought to inquest? The rules direct that the arrested person be released and the case returned to the referring agency for possible refiling, and the responsible officer may face liability for the delay.
