Cause-in-Fact
Did the violation actually cause harm?
But-For Causation
Rule
RTT: when a single Δ is potentially liable for Π’s harm, Δ caused-in-fact the harm if the harm would not have occurred but for the negligence or liable conduct.
The burden is generally on the Π and is a preponderance of the evidence standard (more likely than not) (Grimstad);
exception: when Δ’s negligence prevented / destroyed evidence that would suggest causation (“insult to injury”), rebuttable presumption of causation (burden shifts to Δ) (Haft).
Analysis
But-For Causation
The relevant causation is heavily dependent on underlying liability; if Δ is liable because drove truck where it didn’t belong, Π must prove weight was enough to harm pipes. But if Δ is liable because drove truck exceeding max weight, Π must prove the excess weight caused harm.
Burden Shifting
The “insult to injury” rule is designed to “stick it to the breacher”; if the Δ’s negligence is the reason why Π can’t prove causation, the Δ should have to.
Posner in Indiana Harbor Belt notes that destroyed evidence may lead to strict liability.
Cases
N.Y. Cent. R.R. v. Grimstad (2d Cir. 1920, 451): Π drowned and wife saw him drowning but boat did not have life buoy on board; no but-for causation, since no guarantee Π would more likely than not have survived with one.
Squibs
But-For
Ford v. Trident Fisheries (Mass. 1919): Δ not liable for not having accessible lifeboats since no proof boat would have saved Π in time.
Kirincich v. Std. Dredging Co. (3d Cir. 1940): whether Δ is liable for inadequate lifesaving equipment is question for jury.
Reyes v. Vantage Steamship Co. (5th Cir. 1980): question of fact whether, had Δ had rocket-powered line thrower (in line with statute), Δ would have saved drowning sailor; since only 15% chance it would have saved Π, Δ not liable.
Burden Shifting
Haft v. Love Palm Hotel (Cal. 1970): Δ has burden to prove no causation when Π drowned in pool without lifeguard, since the lifeguard would have at least witnessed how Π died.
Schuabe v. Custer’s Inn Ass’n (Mont. 2000): Δ had a sign warning that pool had no lifeguard, but no CPR-trained personnel nearby as required; still, burden does not shift, since Π was underwater for long time and CPR-trained personnel would not have saved him anyway.
Substantial Factor Test
Rule
California / Minority Rule: cause-in-fact satisfied if the liable conduct was a substantial factor in the injury:
if Δ’s act was wrongful because it increased the risk of a harm, and that type of harm occurred (e.g. negligence per se or Herzog) there is at least a permissive inference of causation (Zuchowicz).
The opinion could also be read to provide in strong cases for a rebuttable presumption of causation and burden shift to Δ to disprove causation (Shugerman).
Manufacturing defects: the product departs from the intended design.
If the malfunction is ordinarily a result of a defect and not due to the Π or other causes (similar to res ipsa), there is an inference of causation (RTT:PL § 3).
Analysis
The “substantial factor” test is generally used when there is uncertainty; may be a supplement for the but-for test and function as a risk multiplier, e.g., if Δ’s conduct was a substantial factor in multiplying the risk of Π falling, Δ may be liable. (Reynolds; FFTL 104).
California uses this rule instead of the but-for test because the but-for test is overly prejudicial to Πs.
Shugerman believes this should replace all but-for causation because it is less formalistic and overcomes the problems with multiple Δs.
Cases
Zuchowicz v. United States (2d Cir. 1998, 455)(Calabresi): Δ violated FDA regulation concerning “overdose” that aimed to prevent risk of harm that resulted; permissive inference of causation (no direct evidence needed).
Reynolds v. Tex. & Pac. Ry. (La. 1885): 250-lb Π fell down unlighted staircase; Δ might have but-for caused fall by not lighting stairs, but certainly multiplied risk (substantial factor).
Lost Chance
Rule
When Δ is a doctor who increased Π’s risk of harm, and harm occurred (lost chance) Δ is proportionally liable for the change in Π’s odds of survival if the change is below 50 percent (Pearson concurring, Herskovitz);
common rule: calculate change by subtracting new chance from old chance.
if it is not more likely than not that but for the negligence, Π would not have been harmed (e.g. chances fall from 85% to 61%), Π gets proportionate damages (e.g. 24%);
if it is more likely than not that but for the negligence, Π would not have been harmed (e.g. chances fall from 85% to 20%), Δ responsible for 100% of damages;
minority: Π always gets proportionate damages (65% here)(Fennell).
Shugerman / FFTL rule: calculate change by dividing change in odds due to negligence by Π’s new odds of harm;
if it is not more likely than not that but for the negligence, Π would not have been harmed (e.g. chances fall from 85% to 71%, or negligence is responsible for [14/29]% or 48.3% of the harm), Δ responsible for proportionate damages (e.g. 48.3%).
if it is more likely than not that but for the negligence, Π would not have been harmed (e.g. chances fall from 85% to 20%, or negligence is responsible for [65/80]% or 81.2% of the harm), Π gets 100% damages.
Analysis
The idea behind the lost-chance doctrine is it give doctors an incentive to administer quality care to critical patients, since even though patients may already be more likely than not to die without the doctor’s help, the doctor will be liable if this percentage increases due to their negligence (Holton v. Memorial Hospital (Ill. 1997)).
Generally does not apply to non-medical contexts; if the non-existent lifesaver in Kirincich would have increased Π’s survival odds from 0% to 33%, Δ would still not be liable.
Cases
Herskovitz v. Group Health Cooperative (Wash. 1983, 470): Π was negligently treated for tumor and chance of survival fell from 39% to 25%; Δ liable for reducing chance of survival by 14%, even though did not make it more likely than not that Δ died.
Squibs
Verdicchio v. Ricca (N.J. 2004): in case where Π had 85% chance of surviving before cancer spread but only 20% after misdiagnosis, Π gets 100% damages.
Fennell v. S. Md. Hosp. Cent., Inc. (Md. 1990): when doctor’s negligence reduces Π’s chances from 51% to 0%, Π should only get 51% of recovery (minority).
Probable Future Consequences
Rule
When Δ is more than 50% likely to contract a disease because of Δ’s negligence, Π may recover for “probable future consequences.”
Analysis
This is obviously super hard to prove. For Damages, see infra.
Cases
Jackson v. Johns-Manville Sales Corp. (5th Cir. 1986): Π with asbestosis can receive damages for “probable future consequences” since Π is more than 50% likely to get cancer.
Joint and Several Liability
Rule
RTT: if multiple Δs each could have caused harm to Π, each Δ faces joint and several liability.
joint and several liability = each Δ individually responsible for the entire harm (Δs may split or indemnify burden);
Exceptions:
RST: if acts may be apportioned among two or more causes discretely or in terms of degree, damages may be divided among Δs proportionally;
if one act was large enough to subsume the other (e.g. a giant fire), only the greater tortfeasor is responsible (Kingston);
old exception: if one act was natural, the other actors are not liable (Kingston);
RST: if one act was of unknown origin, burden shifts to Δ to prove act was not the cause of damage (which is obviously impossible);
Analysis
The idea behind JSL is that two tortfeasors should not be allowed to escape just because they fail a formalistic test, when they were each clearly liable for Π’s harm.
Cases
Kingston v. Chicago & Nw. Ry. (Wis. 1927, 477): fire caused by Δ mixed with fire of unknown origin, burning Π’s house; burden is on Δ to prove that the other fire was not much larger or naturally caused.
Squibs
Smith v. J.C. Penney Co. (Or. 1974): Π was injured by Δ1’s flammable coat and Δ2’s gasoline fire; both Δs are JSL.
Browning v. Ringel (Idaho 2000): when Π had preexisting conditions that Δ exacerbated, but it was unclear how much new pain was actually caused by Δ, Δ should only be partially liable.
Piner v. Super. Ct. (Jones RPI) (Ariz. 1998): where two successive accidents injured Π and both Δs negligent, JSL since the result is indivisible.
Alternative Causation
Rule
RST: if only one of a few possible Δs harmed Π but there is uncertainty about which Δ, the burden shifts to each Δ to prove own act did not cause harm;
old rule: when Π can’t prove which of two Δs was liable, neither is (Adams v. Hall (Vt. 1829));
old exception: where Δs acted in concert, both liable (Summers).
Analysis
This rule generally applies when there are only a few possible Δs. If three Δs are each 33% likely to have caused Π’s harm, courts recognize that each less-likely-than-not caused the harm, but Π should not be responsible.
Cases
Summers v. Tice (Cal. 1948, 485): two hunters shot Π accidentally, but only one of the two hit Π in the eye; JSL, and the Δs have burden to allocate responsibility between themselves.
Enterprise Liability
Rule
If connected actors in an industry acted in concert to avoid liability, Π may establish that any of the actors caused harm to hold all actors liable (Du Pont);
Π must be able to identify the wrongdoers or Δs that acted in concert (Skipworth);
If Δs acted in concert and there is...
