Under section 228 StPO, the main trial is public as a rule. Section 229 StPO permits exclusion only for specific reasons and only to the extent required to protect prevailing legitimate interests. The judgment must always be pronounced publicly.

This post explains when exclusion may be considered because of public order, national security, private or confidential matters, or protection of a person’s identity. It also explains who may apply, how the order is announced and which persons may remain in the courtroom. It distinguishes this issue from the general course of a main trial and from a trial in the absence of the accused. Further information is available in the related posts below.

Public nature of the criminal trial

Assessing exclusion of the public.

01

A partial exclusion may be considered before private or confidential matters are discussed.

Section 229(1)(2) StPO refers to the private life or secrecy of an accused person, victim, witness or third party. The assessment must identify precisely which part of the trial concerns that information. The exclusion can be limited to that part where a complete exclusion is unnecessary.

The statutory grounds →
02

The public may be excluded to protect the identity of a witness or third party.

Section 229(1)(3) StPO refers to the reasons for identity protection set out in section 162 StPO. The concrete risk and the part of the trial concerned are therefore decisive. The reasons should connect the protected interest with the requested scope of the exclusion.

How the court decides →
03

A risk to public order or national security is a separate ground for exclusion.

Section 229(1)(1) StPO covers a risk to public order or national security. This ground requires a concrete assessment of the expected risk. The court must also decide whether the exclusion should cover the whole trial or only a particular part.

All statutory grounds →
04

The exclusion order and the judgment must still be announced publicly.

Under section 229(3) StPO the exclusion order and its reasons are announced in a public sitting. Section 229(4) StPO requires the judgment to be pronounced in public in every case. After the public announcement of the exclusion order, the audience must leave unless section 230 StPO permits protected persons to remain.

Why the main trial is public as a rule

Section 228(1) StPO provides that the main trial is public, failing which the proceedings are subject to nullity. Public access allows scrutiny of criminal justice and forms part of the basic rules of the procedure. The principle concerns the access of members of the public to the trial.

Public access has limits. As a rule, only unarmed persons may participate or attend. Minors may be excluded if their presence could endanger their personal development. Television and radio recordings or broadcasts, as well as film and photography of court proceedings, are prohibited under section 228(4) StPO. These rules concern access and the conduct of the trial. The specific exclusion under section 229 StPO additionally requires one of the grounds listed there.

The grounds listed in section 229 StPO

Section 229(1) StPO permits exclusion because of a risk to public order or national security. It also permits exclusion before the private life or secrecy of an accused person, victim, witness or third party is discussed. The third ground protects the identity of a witness or third party for the reasons referred to in section 162 StPO.

The assessment must relate to the concrete part of the trial. A private or confidential sphere may be affected only during a particular discussion. Where there is a risk, the court must identify when it arises and how long it lasts. This distinction matters because section 229(2) StPO allows exclusion of the whole trial or only part of it.

The exclusion is tied to prevailing legitimate interests that require protection. The court must therefore relate the statutory ground, the interests affected and the necessary scope to one another. A general wish for less attention does not replace this assessment.

Section 229(1) StPO

The three statutory grounds for exclusion

The reason determines which protection issue the court must examine.

Statutory grounds for excluding the public from the main trial
Ground What it covers Scope
Public order or national security A concrete risk to public order or national security. The risk must be connected to the trial and assessed in scope.
Private life or secrecy Protection before private or confidential matters of an accused person, victim, witness or third party are discussed. The court must identify the affected part and whether a partial exclusion is sufficient.
Protection of identity Protection of a witness or third party for the reasons in section 162 StPO. The concrete risk and necessary scope must be understandable.

Who may apply and who decides

The court may order exclusion on its own initiative. Under section 229(1) StPO, a participant in the proceedings or a victim may also apply. The application should identify the statutory ground, the part of the trial concerned and the requested scope. It may concern the whole trial or a specific part.

The court with lay judges decides on exclusion by order at any stage of the proceedings. This also applies when the issue first arises during the main trial. The order and its reasons must be announced in a public sitting. The public announcement makes the decision understandable before the audience leaves the courtroom.

There is no separate remedy against the exclusion order that suspends the further conduct of the trial. This rule concerns the order about public access. It does not determine which remedies may be available against the judgment or other decisions in the criminal proceedings.

Who may remain after exclusion

After the public announcement of the exclusion order, all members of the audience must generally leave. Section 230(2) StPO creates exceptions. Judges and public prosecutors in active service, judicial trainees and legal trainees may never be excluded. The same applies to the persons named in section 48(1)(5) StPO.

An accused person, victim, private party or private prosecutor may demand that three persons of their confidence be admitted. This creates a statutory possibility of keeping support from trusted persons during a non-public trial. The persons chosen and the practical arrangements in the courtroom should be clarified with the court in good time.

Section 230(2) StPO also applies section 160(2) and (3) StPO by analogy. The case file therefore remains important for the precise implementation. Exclusion of the general public does not mean that every person who is not a participant may stay without further examination.

Why the judgment remains public

Under section 229(4) StPO, the judgment must always be pronounced in a public sitting. This also applies where the public was excluded for individual parts or for the remainder of the trial. The judgment is therefore pronounced during a public part of the sitting.

The exclusion order itself is also announced publicly together with its reasons. The audience must then leave unless a person is legally protected or a trusted person is admitted under section 230(2) StPO. The public decision and the non-public discussion of protected content are kept separate in this way.

Exclusion changes access to the main trial. It does not decide whether the accused is personally present. For that separate procedural issue, see the post on a trial in the absence of the accused. The general course of the main trial is explained in the post on the main trial in criminal proceedings.

The application turns on the specific protection issue. Describe which information or person is to be protected, which part of the trial is concerned and why the requested scope is necessary. The order and the judgment remain subject to public announcement.

The main trial is public as a rule under section 228(1) StPO. Section 229 StPO allows exclusion for specific reasons, including protection of private or confidential matters or a witness’s or third party’s identity. The exclusion may cover the whole trial or only part of it.
