Term and definition of disqualification in criminal proceedings

Disqualification (Strafausstand) is a technical term from German criminal procedure law. It refers to the temporary or permanent exclusion of certain persons—particularly judges, public prosecutors, or lay judges—from participating in a specific criminal proceeding due to statutory or actual grounds for removal. The purpose of disqualification is to ensure impartiality and fairness in criminal proceedings and is a central tool for safeguarding the right to a fair trial under Article 6 of the European Convention on Human Rights (ECHR) and Article 101(1) sentence 2 of the Basic Law (GG).

Legal foundations for disqualification

Statutory basis in German law

The applicable rules for disqualification are primarily found in the German Code of Criminal Procedure (StPO):

  • Sections 22–30 StPO set out the grounds and procedures for disqualification.
  • Section 22 StPO regulates the mandatory grounds for exclusion (absolute grounds for disqualification).
  • Sections 23 ff. StPO regulate the procedure for exclusion due to concerns of bias (relative grounds for disqualification).

Function and purpose

Disqualification protects the neutrality and objectivity of decision-makers involved in the criminal process. Its main function is to prevent both actual and apparent bias and thus to maintain the confidence of the parties involved in the justice system.

Types of grounds for disqualification

Absolute grounds for disqualification (§ 22 StPO)

Absolute grounds for disqualification are circumstances that, by law, exclude the person concerned from participation. Absolute grounds for disqualification include, among others:

  • Involvement of the relevant person as an injured party, witness, complainant, or expert in the same proceedings.
  • Family or other close personal relationships with a party.
  • Previous work as counsel, adviser, or legal representative of the accused.

In the case of absolute grounds for disqualification, the person concerned is prohibited from participating; a formal application procedure for removal is not required, but exclusion occurs ex officio.

Relative grounds for disqualification (bias, § 24 StPO)

Relative grounds for disqualification exist, for example, when there is concern of bias. This means that objective reasons must exist which, when reasonably evaluated, could give rise to doubts about the impartiality or objective decision-making of the participant.

Those entitled to file an application for bias are generally the parties to the proceedings (the accused, defense, prosecution).

Procedure for application on grounds of bias

The procedure begins with a formal application alleging bias. The grounds must be presented in detail. The person concerned has an opportunity to respond to the application. The decision on the application is taken by the remaining members of the court without the participation of the challenged member.

Persons involved in disqualification

Disqualification can be requested or occur by operation of law for:

  • Judges (professional judges, lay judges/Schöffen)
  • Public prosecutors
  • Court clerks, judicial officers (in certain situations)

Unlike in civil proceedings, criminal law has specific regulations tailored to the particularities of criminal procedure.

Legal consequences of disqualification

Prohibition of participation

If grounds for disqualification exist, the person concerned must generally be excluded from participating in the proceedings. Violations may affect the validity of a decision or even lead to an appeal (§ 338 No. 3 StPO).

Repetition of procedural acts

If procedural acts were carried out with the participation of an excluded or disqualified person, these acts may be invalid and, if necessary, must be repeated.

Procedural particularities

Application for rejection and its handling

The application for rejection must be filed with the court at the latest before the start of the taking of evidence. If grounds for rejection become known later, the application can also be made subsequently. Applications that are obviously unfounded or constitute an abuse of rights may be rejected without detailed examination.

Appeals and reviewability

Decisions on disqualification cannot generally be challenged immediately by separate appeal, but may be subject to review together with appeals against the final judgment (see § 28 StPO).

Disqualification in comparison: International law and German particularities

While the institution of disqualification exists in comparable form in many legal systems, German law places special emphasis on a clearly regulated and formalized procedure for asserting and reviewing grounds for disqualification. The close link to procedural guarantees under the Basic Law and the ECHR is reflected in the design of the legal institution.

Importance of disqualification for the rule of law

Disqualification is an essential pillar of the rule of law in criminal justice. It ensures not only the neutrality and impartiality of the key decision-makers, but also the public’s confidence in a just and fair criminal trial.

References and case law

For further detailed information, relevant commentaries on the StPO as well as relevant decisions of the Federal Court of Justice (BGH), the Federal Constitutional Court (BVerfG), and the European courts should be consulted. The literature particularly addresses the distinction between absolute and relative grounds for disqualification, the procedure, and the consequences of procedural errors in disqualification.


Summary: Disqualification under German criminal procedural law offers a comprehensive protection mechanism to ensure impartial judicial decisions and is an important instrument of procedural justice. Its regulations, objectives, and enforcement ensure objective decision-making and safeguard effective legal protection for all parties to the proceedings.

Frequently asked questions

What legal requirements must be met for disqualification in criminal proceedings?

For disqualification—that is, the temporary suspension of criminal proceedings—certain legal requirements must be met according to the relevant criminal procedure regulations. Disqualification is generally ordered when there are so-called grounds for disqualification that would compromise the proper conduct of the proceedings. Typical reasons include a party to the proceedings who is heavily pregnant or acutely ill, unavoidable absence of a key participant (such as a witness or defense counsel), pending preliminary questions in another judicial proceeding (e.g., in a civil case upon which the outcome of the criminal case depends), or a judge who is seriously ill. The crucial factor is always that, without disqualification, the proceedings could not continue fairly or in accordance with the law. The decision on disqualification is made by the court through a formal order stating the reasons.

What impact does disqualification have on the course of criminal proceedings?

The order for disqualification leads to the interruption of the ongoing criminal trial at the relevant instance. During this period, no hearings are held and no procedural actions affecting the main proceedings may be conducted. Deadlines running during the proceedings—such as deadlines for filing legal remedies—are generally suspended and resume only after the disqualification has been lifted. As a result, all parties—including the accused, prosecution, and defense—are given the opportunity to adjust to changed circumstances. Important taking of evidence is not conducted, hearings are not held, and judgments are not delivered as long as the disqualification is in effect.

How does the court decide on disqualification and who can file an application for disqualification?

The decision on disqualification is always made by the competent court by means of a formal, reasoned order. The application for disqualification may be filed by defendants, their defense, the prosecution, or in some cases by witnesses or experts, provided they can credibly demonstrate a valid ground for disqualification. The court then examines whether the legal requirements are met and whether the continuation of the proceedings would be unreasonable or impossible. In some cases, the court can also order disqualification ex officio, for example due to its own disqualification grounds of judges or due to mandatory, unforeseen events. An appeal against the order is generally permitted (e.g., complaint), unless the law excludes it.

What happens to detained defendants during disqualification?

In the event of disqualification, special issues arise in relation to detained defendants. In principle, the ordering of disqualification must not result in an unlawful extension of pre-trial detention. The court is obliged, within the deadlines for reviewing detention, to verify whether and for how long the continuation of detention is compatible with the principle of proportionality. In the case of prolonged disqualification, measures for release from pre-trial detention may be ordered or the detention review date must be brought forward accordingly. The right to liberty remains a highly protected interest; thus, the judiciary is obliged, even during periods of disqualification, to regularly examine whether and for how long the detention order is still justified.

Can disqualification be lifted retroactively or declared void?

Disqualification generally cannot be lifted retroactively, as the interruption of proceedings always has a de facto legal effect. However, if it is later established that the underlying ground for disqualification did not exist (e.g., manipulation of a medical certificate confirmed afterward), the proceedings may be resumed, but procedural acts conducted during the disqualification period remain generally invalid. In exceptional cases, the court may, within the bounds of the rule of law, provide for subsequent remedial measures for procedural errors. An explicit reversal of the disqualification, however, does not normally take place.

Are there any time limits for the duration of disqualification?

The duration of disqualification is not generally set by law, but always depends on the particular ground for disqualification. Disqualification persists only as long as the underlying ground continues to exist. The court is required to regularly review the ground for disqualification and lift it without delay as soon as the requirements fall away. In the case of longer disqualifications, for example due to complex preliminary questions or illnesses, it is often checked at short intervals whether the ground for disqualification still exists. Moreover, there is an obligation to limit disqualifications to the absolutely necessary duration so as to avoid unnecessary delays in the criminal process.
