Syyseurausvaikutus

Syyseurausvaikutus, often translated as causal linkage or causal connection, refers to the principle in Finnish law and legal reasoning that establishes a demonstrable relationship between an action or omission and a resulting harm or consequence. It is a fundamental concept in determining legal responsibility, particularly in civil and criminal cases.

To establish syyseurausvaikutus, it must be proven that the act or failure to act was a necessary condition for the occurrence of the harm. This is often assessed through a "but-for" test: would the harm have occurred if the action or omission had not taken place? If the answer is no, then a causal link is likely established.

However, the concept is not always straightforward. Finnish legal practice also considers the adequacy of causation, meaning that even if an action was a but-for cause, the connection might be deemed too remote or improbable to establish legal responsibility. This can involve assessing foreseeability of the harm and the directness of the causal chain.

In criminal law, syyseurausvaikutus is crucial for proving guilt. For example, in a homicide case, the prosecution must demonstrate that the defendant's actions directly caused the victim's death. In civil law, it is essential for awarding damages, as compensation is generally only granted for harm directly resulting from the defendant's wrongful act. The burden of proof for establishing syyseurausvaikutus typically rests with the party making the claim.
