I agree its the "but-for" causation in law:
[...]
In legal matters, "but-for", "sine qua non", causa sine qua non,<a href="Sine qua non - Wikipedia"><span>[</span>9<span>]</span></a> or "cause-in-fact" causation, or condicio sine qua non, is a circumstance in which a certain act is a material cause of a certain injury or wrongdoing, without which the injury would not have occurred. It is established by the "but-for" test: but for the act having occurred, the injury would not have happened.
>The defendant's negligent conduct is the actual cause of the plaintiff's injury if the harm would not have occurred to the plaintiff "but for" the negligent conduct of the defendant. (Perkins)>
