Every defendant in a wreck case would like to have been scenery. “My client’s negligence merely furnished a condition” is the sentence that asks a court to treat a speeding car, a stopped truck or an unlit trailer as part of the landscape in which the real cause happened. Texas law has a test for it, and this week the Fifth Circuit said who applies the test: the jury.
The test is two questions, and this is the first one. In Texas, “Proximate cause requires a showing of both cause in fact and foreseeability.” Cause in fact “turns on ‘whether the act or omission was a substantial factor in causing the injury without which the harm would not have occurred.’” And then the line: “If the defendant’s negligence merely furnished a condition that made the injuries possible, there can be no cause in fact.” Foreseeability, the second question, “requires that a person of ordinary intelligence should have anticipated the danger created by a negligent act or omission,” and is “a highly fact-specific inquiry” (Payne v. City of Houston, quoting the Texas Supreme Court). The foreseeability half, the one a judge named Cardozo built on a train platform, is Proximate Cause. This entry is the other half.
Substantial factor has two parts, and the defense usually attacks only one. The first is but-for: the harm would not have occurred without the negligence. The second is substance: the negligence did some of the work, rather than merely being present. A condition is a thing that was there and did nothing. A cause is a thing that was there and did something. A pole beside the road furnished a condition for the car that left the road and hit it; the pole did not move. A car doing seventy in a thirty-five did move, and the turn across its path that would have been safe at the limit was not, which is the arithmetic Distance Lies lays out. The difference between the two is not where the defendant was. It is whether the defendant’s negligence changed what happened.
The Fifth Circuit’s Houston case is the clean example. A patrol car doing up to 70 in a 35, lights and siren off, its driver looking at his laptop, struck the passenger side of a car turning left across its lanes, and the driver of that car died. The City argued that the officer neither breached a duty nor caused the collision. The opinion also recites that the man who died was diabetic, was having a heart attack and was under the influence of marijuana, the kind of facts a defense builds a condition argument from. The panel did not resolve it. It named it: “Whether Cabrera’s speeding and inattention were substantial factors in causing Payne’s injuries, or ‘merely furnished a condition that made the injuries possible,’ is perhaps the quintessential dispute driving this case,” and because the family’s expert had testified that at the speed limit the patrol car “would not have collided with Payne’s vehicle,” the question belonged to a jury, not to a motion. “That the City disputes these facts merely proves the point: Summary judgment is improper in this instance” (Payne v. City of Houston; the entry is here).
The move: answer the two halves separately, because the defense will try to make the second one sound like the first. The but-for half is arithmetic, and the sentence that wins it is the expert’s: at the lawful speed the car would not have been there yet; with the triangles out the driver would have had two seconds he did not have; with the load braced the cab would have held. That sentence is built from the event data recorder, the point of impact, the distances and the times, which is why the first letter in the case asks for the recorder (Spoliation). The substance half is a story about what the negligence did, told in the present tense: the speed takes the gap away, the missing triangle takes the warning away, the unbraced load becomes a second vehicle. A condition sits still in that story. A cause acts. Then remember three things the defense would rather you forgot. Texas does not require the only cause; it divides fault in whole numbers among everyone whose negligence was a cause (Comparative Fault), so the turn being a cause does not make the speed a condition. A stopped truck is not always a condition, because a truck that stopped where it did, with no warning out, when the rule gave its driver ten minutes to put one out, did something, which is Warning Devices. And the victim’s own condition, the heart, the blood, the medicine, is a fact for the jury to weigh beside the defendant’s, not a trapdoor under the case; the Houston opinion recited those facts and sent the question to trial anyway. One caution. The argument is sometimes right. A car that was speeding and is hit from behind while stopped at a red light did furnish a condition, because the speed had already ended when the harm began. The test is honest; the task is to show which side of it the facts are on, and the arithmetic usually knows.
