IDJI 2.30.2
Proximate cause – “substantial factor,” without "but for" test.
When I use the expression "proximate cause," I mean a cause that, in natural or probable sequence, produced the injury, the loss or the damage complained of. It need not be the only cause. It is sufficient if it is a substantial factor in bringing about the injury, loss or damage. It is not a proximate cause if the injury, loss or damage likely would have occurred anyway.
There may be one or more proximate causes of an injury. When the negligent conduct of two or more persons or entities contributes concurrently as substantial factors in bringing about an injury, the conduct of each may be a proximate cause of the injury regardless of the extent to which each contributes to the injury.
