What Is an Order to Open Oral Trial Proceedings?

Few judicial decisions generate as much concern as an order to open oral trial proceedings (auto de apertura de juicio oral). Receiving it marks a very clear turning point in criminal proceedings: it means that the investigation has concluded, that the prosecution considers there is sufficient evidence to sustain a trial, and that the case will be heard by a court that must rule on the guilt or innocence of the accused. For the person receiving it, the immediate question is always the same: what exactly does this mean and what will happen next?

The order to open oral trial proceedings is a key resolution in the structure of the Spanish criminal process. It is not a conviction, nor even a definitive accusation: it is the judicial decision that determines that the criminal proceedings have sufficient basis to advance to their most important and visible phase. Understanding what it is, what it contains, who issues it, when it is issued, and what consequences it entails is essential in order to face the stage that begins from that moment with proper guarantees.

In this article, we explain in a complete and clear way everything you need to know about the order to open oral trial proceedings: its legal nature, the procedural stage in which it appears, its content, the differences with other similar resolutions and, above all, what the person who receives it must do to protect their rights and build the best possible defence.

What Exactly Is an Order to Open Oral Trial Proceedings?

The order to open oral trial proceedings is a judicial resolution issued by the investigating judge—or, where appropriate, by the criminal court judge—by means of which the holding of the oral trial in criminal proceedings is formally agreed. Its issuance brings the intermediate phase of the process to an end—that stage which separates the investigation from the trial—and gives way to the oral hearing, which is the central act of the proceedings in which evidence will be presented, the parties will be heard, and the court will decide on the guilt or innocence of the accused.

From the perspective of its legal nature, the order to open oral trial proceedings is a procedural resolution, not a substantive one. This means that it does not prejudge the outcome of the trial nor does it declare the accused guilty of anything: it simply confirms that the necessary procedural requirements exist for the criminal proceedings to move forward to their final stage. The decision on the guilt or innocence of the accused corresponds exclusively to the court that holds the oral trial, not to the judge who issues the order.

For the suspect—who from this moment becomes formally accused—the order to open trial represents the beginning of the most delicate stage of the process. But it also marks the moment when the defence has all the necessary information to prepare its strategy: it is now known exactly what facts are being alleged, under which criminal classification those facts are framed, what evidence the prosecution proposes, and what penalty is being requested.

At What Stage of the Process Is the Order Issued?

To properly understand the order to open oral trial proceedings, it is essential to place it within the structure of the abbreviated criminal procedure, which is the framework in which it most frequently appears. This procedure has three major phases: the investigation (preliminary proceedings), the intermediate phase, and the oral trial. The order to open proceedings is precisely the resolution that closes the intermediate phase and opens the trial.

The intermediate phase begins when the investigating judge declares the preliminary proceedings concluded and gives notice to the parties so that they may file their submissions. At that point, the public prosecutor and, where applicable, the private prosecution must decide whether to file an indictment—formally setting out the charges against the suspect—or to request dismissal of the case. The defence, for its part, files its defence statement, in which it may deny the facts, present an alternative version, propose exculpatory evidence, or argue mitigating or exonerating circumstances.

Once all submissions have been received, the judge assesses whether the necessary requirements to open the oral trial are met. If at least one prosecuting party maintains the accusation and the judge finds that there are reasonable indications of criminality, the order to open proceedings is issued. If, on the contrary, no party sustains the accusation or the judge considers the evidence insufficient, a dismissal order is issued and the case is closed without going to trial.

What Must the Order to Open Oral Trial Proceedings Contain?

The order to open oral trial proceedings is not a lengthy document, but its content is extremely important because it defines the framework within which the oral trial will take place. It must include the following elements:

• The identification of the accused person or persons against whom the proceedings are directed
• The facts considered sufficiently established to justify holding the trial, described with sufficient precision so that the accused knows exactly what they are being held responsible for
• The offence or offences charged, with reference to the relevant provisions of the Criminal Code
• The penalty or penalties requested by the prosecution, which is one of the most important aspects for the accused as it allows them to assess the maximum risk they face
• Any precautionary measures that are maintained or adopted in relation to the oral trial
• The court competent to hear the case: the Criminal Court or the Provincial Court, depending on the seriousness of the offence

Carefully reading the order—and especially the indictments that accompany it—is essential to fully understand the accused’s procedural situation and to allow their lawyer to prepare the defence with all relevant elements available.

Who Issues the Order and Before Which Court Is the Trial Held?

In abbreviated proceedings, the order to open oral trial proceedings is issued by the investigating judge who conducted the investigation phase. However, and this is a fundamental procedural guarantee, the judge who issues the order is not the same judge who conducts the oral trial or delivers the judgment.

Once the order is issued, the case is transferred to the Criminal Court if the offence carries a maximum sentence of up to five years’ imprisonment—or up to ten years for non-custodial penalties—or to the Provincial Court if the penalty exceeds that threshold. For certain particularly serious or complex offences, such as terrorism or offences involving high-ranking public officials, jurisdiction lies with the National Court.

This separation between the investigating authority and the adjudicating court is not a mere technicality: it is an essential guarantee of impartiality. The court that decides on the accused’s guilt has not had prior access to all the information gathered during the investigation—particularly material that will not be admissible at trial—allowing it to assess the case with the objectivity required.

How Does It Differ from Other Similar Judicial Orders?

The order to open oral trial proceedings is sometimes confused with other resolutions in criminal proceedings:

Order to Open Proceedings vs. Order Initiating Preliminary Proceedings

The order initiating preliminary proceedings marks the beginning of the investigation. The order to open trial marks its end and the start of the trial.

Order to Open Proceedings vs. Indictment Order (Auto de procesamiento)

The indictment order applies in ordinary proceedings (for more serious offences) and serves a similar function, but in a different procedural framework.

Order to Open Proceedings vs. Dismissal Order

The dismissal order is the opposite: instead of opening trial, it closes the case due to lack of evidence or absence of a criminal offence.

What Are the Consequences for the Accused?

Receiving this order has immediate and practical consequences:

• The accused now knows precisely the facts, charges, and requested penalties
• The time frame to prepare the defence and propose evidence is activated
• Only evidence proposed at this stage may be admitted at trial
• Precautionary measures may be maintained or modified

Defence Strategy After the Order: Why Every Decision Matters

This is one of the most critical stages for the defence. The lawyer must:

• Analyse the indictment in detail
• Assess the strength of the prosecution’s evidence
• Design a trial strategy
• Prepare the accused for testimony

A key decision is whether to accept a plea agreement (conformidad). This involves admitting the facts in exchange for avoiding trial and potentially receiving a reduced sentence. It may be advisable in certain cases, but it entails accepting a conviction and must be carefully considered.

If the case proceeds to trial, preparation must be meticulous. Improvisation at trial can be extremely costly.
