Substantive German Criminal Law

Sources and the Basic Law Framework

German criminal law (Strafrecht) is codified in the Strafgesetzbuch (StGB), which traces its origins to the Criminal Code of the German Empire of 1871 (Reichsstrafgesetzbuch), substantially reformed in 1975 and amended numerous times since. The StGB is divided into a General Part (Allgemeiner Teil, §§ 1-79b) and a Special Part (Besonderer Teil, §§ 80-358). The General Part sets out fundamental principles, the structure of liability, theories of punishment, rules on attempt, participation, and the system of sanctions. The Special Part defines specific offences, generally organised by the legal interest (Rechtsgut) protected. Constitutional constraints are paramount: Article 103(2) of the Basic Law (Grundgesetz, GG) codifies the principle of nulla poena sine lege, requiring that an act be declared punishable by law before it was committed. Article 1(1) GG guarantees human dignity, which the Federal Constitutional Court (Bundesverfassungsgericht) has held requires that punishment be proportionate and respect the offender’s personhood.

The Three-Part Structure of Criminal Liability

German criminal law doctrine analyses liability through a rigorous three-part structure. The first level, Tatbestandsmäßigkeit (commission of the statutory elements), requires that the defendant’s conduct satisfies all objective and subjective elements of the offence definition. The objective Tatbestand includes the act or omission, its consequences, causation, and any circumstances specified by the offence. The subjective Tatbestand generally requires intention (Vorsatz), defined as knowledge and will to realise the elements of the offence, encompassing three forms: intent (dolus directus of the first and second degree) and conditional intent (dolus eventualis), where the actor seriously considers the possibility that the elements will be realised and accepts that possibility.

The second level, Rechtswidrigkeit (wrongfulness), examines whether conduct that satisfies the Tatbestand is justified. If the conduct satisfies an offence definition, wrongfulness is presumed but rebutted by the presence of a justification ground. Recognised justifications include self-defence (Notwehr, § 32 StGB), which is broader than in many common law systems, permitting any force necessary to repel an imminent unlawful attack without a proportionality requirement; necessity (rechtfertigender Notstand, § 34 StGB); lawful arrest; and consent (Einwilligung), which can justify conduct where the legal interest is capable of waiver.

The third level, Schuld (culpability), requires that the defendant can be personally blamed for the wrongful act. Schuld requires capacity for guilt (Schuldfähigkeit), which may be excluded or diminished by mental disorder (§§ 20-21 StGB). The defendant must have had the ability to appreciate the wrongfulness of the conduct and to act in accordance with that appreciation. Beyond capacity, Schuld encompasses awareness of wrongdoing (Unrechtsbewusstsein) and the absence of excusing circumstances such as duress (entschuldigender Notstand, § 35 StGB). An unavoidable mistake of law (Verbotsirrtum, § 17 StGB) excludes Schuld; an avoidable mistake may reduce punishment.

Classification and the Principle of Legality

The StGB classifies offences into two categories under § 12. Verbrechen (crimes) are unlawful acts punishable by a minimum of one year’s imprisonment. Vergehen (misdemeanours) are unlawful acts punishable by a lesser sentence or a fine. The classification determines jurisdiction, rules on attempt (attempt liability applies only to Verbrechen unless expressly provided), and ancillary consequences. The principle of legality (Gesetzlichkeitsprinzip) under § 1 StGB and Art. 103(2) GG comprises four elements: the requirement of a written law (nullum crimen sine lege scripta), the prohibition of customary law as a basis for punishment, the prohibition of retroactive criminal law (nullum crimen sine lege praevia), and the requirement of certainty (nullum crimen sine lege certa). The prohibition of analogy (Analogieverbot) forbids courts from extending criminal provisions by analogy to the detriment of the accused, though analogies in favour of the accused are permitted.

Theories of Punishment

German sentencing law under § 46 StGB reflects a synthesis of retributive and preventive theories. The absolute theory (absolute Straftheorie) holds that punishment is justified solely as retribution (Vergeltung) for the wrong committed, restoring the legal order disturbed by the offence. The relative theories (relative Straftheorien) justify punishment by its preventive effects: general prevention (Generalprävention) deters the public from committing crime, while special prevention (Spezialprävention) aims to rehabilitate the offender and incapacitate the dangerous. The Federal Constitutional Court has held that punishment must respect human dignity, require a proportionate relationship to the gravity of the offence, and serve the social reintegration of the offender (Lebach judgment, BVerfGE 35, 202). Section 46(1) StGB provides that the court shall weigh the circumstances in favour of and against the accused, considering the offender’s motive, criminal history, conduct after the offence, and efforts at restitution.

Core Offences

Murder (Mord, § 211 StGB) is distinguished from manslaughter (Totschlag, § 212 StGB) by the presence of specific characteristics (Mordmerkmale): the killing is motivated by murderous lust, sexual gratification, greed, or other base motives; is committed by stealth or with cruelty; uses dangerous means to enable or conceal another offence; or is directed against a particular protected class. The distinction is crucial because Mord carries mandatory life imprisonment, while Totschlag receives a range of five to fifteen years. The Federal Constitutional Court has held that the mandatory life sentence for Mord is constitutional only because of the possibility of early release after fifteen years if the offender’s dangerousness has ceased.

Theft (Diebstahl, § 242 StGB) requires the taking of a movable thing belonging to another with the intent to appropriate it unlawfully. Aggravated theft (§ 243) includes cases involving breaking and entering, use of weapons, or gang membership. Fraud (Betrug, § 263 StGB) requires deception that causes the victim to make a disposition of property resulting in financial loss, with intent to obtain an unlawful material benefit. Assault (Körperverletzung, § 223 StGB) criminalises physical mistreatment or harm to another’s health, with graduated penalties for dangerous assault, serious assault, and assault causing death.

Inchoate Liability and Participation

Attempt (Versuch, § 22 StGB) exists where the perpetrator takes steps toward the commission of the offence according to their conception of the act. The Federal Court of Justice (Bundesgerichtshof) has held that direct commencement occurs when the perpetrator subjectively crosses the “threshold of the now” and objectively takes an act that immediately precedes commission without further intermediate steps. Voluntary withdrawal (Rücktritt, § 24 StGB) from attempt results in impunity if the perpetrator voluntarily abandons further preparatory acts or voluntarily prevents completion.

German criminal law distinguishes between perpetration (Täterschaft) and participation (Teilnahme). Perpetrators include direct perpetrators (unmittelbare Täterschaft), co-perpetrators (Mittäterschaft), who commit the offence jointly on the basis of a common plan, and indirect perpetrators (mittelbare Täterschaft), who commit the offence through another person, typically an innocent agent or a person lacking culpability. Incitement (Anstiftung, § 26 StGB) requires intentionally inducing another to intentionally commit an unlawful act and is punished as if the inciter were a perpetrator. Aiding (Beihilfe, § 27 StGB) requires assisting another in the intentional commission of an unlawful act and carries a reduced penalty. The distinction between co-perpetration and aiding depends on the degree of functional contribution to the offence and the common will to treat the offence as one’s own.

The German Sanctions System

German law imposes two categories of legal consequences for criminal conduct: punishments (Strafen) and measures of rehabilitation and incapacitation (Maßregeln der Besserung und Sicherung, §§ 61-72 StGB). Punishments include imprisonment (Freiheitsstrafe) for a fixed term (one month to fifteen years) or life imprisonment, and fines (Geldstrafe) calculated on a system of daily rates (Tagessätze) reflecting the offender’s net daily income. The court may suspend a sentence of up to two years for probation (Strafaussetzung zur Bewährung), imposing conditions including restitution, community service, or supervision by a probation officer.

The measures of rehabilitation and incapacitation under §§ 61-72 StGB are preventive, not punitive, and address the offender’s dangerousness. They include placement in a psychiatric hospital, placement in a detoxification facility, preventive detention (Sicherungsverwahrung) for dangerous repeat offenders, supervisory conduct instruction (Führungsaufsicht), and forfeiture or confiscation. The Federal Constitutional Court has imposed strict procedural and proportionality requirements on preventive detention, particularly after the European Court of Human Rights held in M v. Germany (2009) that retrospective preventive detention violated Article 7 ECHR, leading to comprehensive reform of the Sicherungsverwahrung regime.
