I think the above answer is correct. If I remember correctly, causation is essentially a 2 part test. You obviously have to show cause in fact, but to fully establish causation, you must also show proximate cause.
In establishing causation, must ask TWO QUESTIONS:
1. Cause in Fact: Historical Q - was the D's conduct a cause for the P's injury?
- "but for"
- Alternatives to the "but for"
- Substantial Factors
2. Proximate Cause: If so, is there a reason the legal system should prevent the D from paying? (scope of liability)
