Criminal cases in which someone is found standing over a corpse with a smoking gun are rather rare. Most verdicts are therefore not based on direct, irrefutable and obvious evidence, such as a clear witness account. The question of guilt or innocence – or at least of guilt that cannot be proven – is then answered via indirect, so-called evidentiary signs, i.e. circumstantial evidence.


In its FOCUS-SPEZIAL series, Focus magazine has surveyed the top commercial law firms for 2023. We are again listed in the category “multidisciplinary top business law firms” as well as for the specialties Compliance and Commercial Criminal Law. Our partner Prof. Dr. Heiko Ahlbrecht is named as one of the top lawyers in criminal law for the West.
