pertinent du point de vue de la causalité

CONT: A source of perplexity has been encountered in certain anomalous situations where there is good reason for saying what an event was caused by a particular act, though it still would have happened without that act. Such cases serve as a reminder that, though the ""but for"" test is satisfactory enough for most purposes, a factor may yet be causally relevant without being a condition sine qua non.
