12 Os 124/25i

OG · Nov 3, 2025

Direct answer

What happened in this matter?

The Austrian Supreme Court identified that the defendant's counsel submitted a filing containing numerous fabricated docket numbers and misrepresented legal authorities. The court formally criticized this conduct for failing to meet the required standard of argumentation for a high court, though it did not impose a specific professional sanction in this decision.

Why the court cared
Fabricated: Case Law | Numerous cited decisions contained incorrect Prüfzeichen (wrong docket numbers) and were relied on by the complaint. || Misrepresented: Case Law | Citation 13 Os 15/17f was cited for the concept of 'Kuriertätern', but the court found the cited decision did not contain that asserted content. || Misrepresented: Case Law | Citation 13 Os 99/15f was cited regarding 'Alias Namen' of telephone calls, but the court found the decision did not support that assertion. || Misrepresented: Case Law | Citation 13 Os 81/07x was cited for a so-called 'Verschleifungsverbot', which the court determined the decision did not establish as claimed. || Misrepresented: Case Law | Citation 14 Os 11/09p was cited for an 'umfassendes Geständnis' and the 'präventive Wirkung der Ersthaftierung', but the court found those content-attributions inaccurate.

Why this matter is tracked

In a criminal proceeding before the Austrian Supreme Court (Oberster Gerichtshof), the court dismissed a fundamental rights complaint filed by a defendant. The court explicitly noted that the complaint contained a high frequency of fabricated case law citations, including incorrect docket numbers (Prüfzeichen) and misrepresentations of the content of cited decisions. The court stated that these errors caused the filing to fall below the standard of argumentation expected of a high court. The court proceeded to address the merits of the complaint where possible, ultimately finding no violation of the defendant's fundamental right to personal liberty and upholding the detention order based on the risk of reoffending.
