Conditio sine qua non or in correct Latin: condicio sine qua non is a Latin expression, which means "condition without which (the result) not (would have occurred)". The form "conditio" is medieval pseudo-latin in analogy with the many Latin words ending on ~ itio, cf. the French condition. (Conditio also exists in Latin, but means fruit or herbal dishes.)
It is a term used in the legal world to indicate the causal link between injurious behavior and the damage. Furthermore, the term causality is used in different fields.
The causal link is of civil law to determine the extent to which damage can be attributed to the debtor. If a conditional-qua non-connection exists, damage may be so far removed from the damage-causing event that the damage is no longer attributable to the perpetrator. Conversely, however, if no conditional-qua non-connection exists, in principle, the damage can not be attributed to the perpetrator. After all, the damage was caused without the damage-causing event.
The term is also used outside of the jurisprudence, more in common as a synonym for the necessary condition. Literatuurverwijzingen
