When people think about personal injury trials, they often imagine dramatic testimony, emotional stories, and lawyers arguing about who was at fault.
But experienced trial lawyers know something many people do not: the outcome of a trial is often shaped by the rules of evidence long before the jury begins deliberating.
Evidence rules determine what the jury is allowed to hear—and what it is not. Here in Connecticut, those Rules are Found in the Connecticut Code of Evidence.
These rules exist for an important reason. Courts want trials to be fair, reliable, and focused on facts that help a jury decide the case. Without rules limiting what evidence can be presented, trials could easily become confusing, misleading, or unfair.
In personal injury cases, evidentiary decisions can affect issues such as:
- whether photographs or videos may be shown to the jury
- whether prior statements from witnesses can be used
- whether repairs made after an accident can be discussed
- whether certain documents can be received by the Jury
- whether witnesses can testify to certain information or opinions
These issues arise in every type of case—including motor vehicle crashes, medical malpractice claims, nursing home negligence, and premises liability cases.
For example, imagine a situation where a poorly maintained stairwell causes someone to fall and suffer serious injuries. Shortly after the incident, the property owner repaired the stairs.
Many people assume that by repairing the stairs, the owner knew the stairs were dangerous. But the law does not necessarily allow that repair to be shown to the jury to prove the owner was negligent.
Why?
Because evidence rules are not only about truth. The rules also reflect important public policies.
In this example, courts want property owners to fix dangerous conditions quickly. If repairs could always be used as evidence of negligence, people might hesitate before correcting hazards—potentially leaving dangerous conditions in place longer.
Evidence rules are therefore designed to balance two important goals:
- allowing juries to hear reliable and helpful information
- encouraging responsible behavior that promotes public safety
Trial lawyers must think carefully about what evidence will be admissible, for what purpose, and how it will be presented. In many cases, important evidentiary issues are decided long before trial through pretrial motions and legal arguments.
One area where these issues frequently arise involves what the law calls “subsequent remedial measures.”
This legal concept addresses a simple but important question:
If a defendant fixes a dangerous condition after an accident, can that repair be used as evidence of negligence in court?
In Connecticut, this situation is controlled by Connecticut Code of Evidence Rule 4-7, which states:
(a) General rule. Except as provided in subsection (b), evidence of measures taken after an event, which, if taken before the event, would have made injury or damage less likely to result, is inadmissible to prove negligence or culpable conduct in connection with the event. Evidence of those measures is admissible when offered to prove controverted issues such as ownership, control, or the feasibility of precautionary measures.
(b) Strict product liability of goods. Where a theory of liability relied on by a party is strict product liability, evidence of such measures taken after an event is admissible.
In reading the Rule, the answer appears to be no—, but there are important exceptions, and the subsequent remedial measures can be used as evidence for another relevant purpose.
And even when excluded initially by the Rules to prove evidence of negligence, if the Defendant were to “open the door” to this issue during the trial, the court can hold that the Defendant waived the protections this Rule affords.
Understanding these rules can make a significant difference in how injury cases are investigated, prepared, and tried before a jury.
In the next article in this series, we will take a closer look at the general rule governing post-incident repairs and why courts typically do not allow those repairs to be used as evidence of negligence.
