When Evidence Disappears: How Nevada’s Spoliation Rules Shape Injury Claims

Casino surveillance systems often record over footage within days. A trucking company’s electronic logs can be overwritten on a routine schedule, and a wrecked car can be crushed at a salvage yard before anyone downloads its data. In many injury cases, the most persuasive proof sits in the hands of the party most likely to be blamed. Nevada law addresses what happens when that proof goes missing, and for our Las Vegas personal injury lawyers, these rules often decide whether a claim rests on solid ground or stalls over a hole in the record.

What Spoliation Means in Practice

Spoliation is the destruction, alteration, or failure to preserve evidence once litigation is reasonably foreseeable. That duty can arise well before a lawsuit is filed. A hotel that writes an incident report the night a guest falls has little room to argue it had no reason to keep the hallway video. The question is usually not whether a business knew about the injury, but when it knew and what it did next.

Two Standards, Two Very Different Outcomes

Nevada separates willful destruction from careless loss, and the difference matters.

Under NRS 47.250(3), Nevada recognizes a disputable presumption that evidence willfully suppressed would be adverse if produced. NRS 47.180 explains the weight of that presumption: the party it is directed against carries the burden of proving the presumed fact is more likely untrue than true. In practical terms, a defendant who deliberately destroyed footage must now disprove what that footage would have shown.

When evidence is lost through negligence rather than intent, Nevada courts have allowed a softer remedy. Jurors may be instructed that they are permitted, but not required, to infer the missing evidence would have been unfavorable to the party who lost it. Courts can also impose discovery sanctions, and in serious cases those sanctions can reach a party’s ability to present its defense. Nevada has declined to treat negligent spoliation as a standalone lawsuit, so these remedies play out inside the injury case itself.

Evidence That Tends to Vanish First

• Surveillance and dashcam video, frequently recorded over in days or weeks
• Vehicle event data recorder information, which can be lost during repairs or salvage
• Commercial truck driver logs, inspection reports, and maintenance records
• Physical objects such as a collapsed chair, a failed ladder, or a rug later replaced
• Phone records, text messages, and social media activity

The Rule Cuts Both Ways

Injured people carry preservation duties too. Repairing a car before it is inspected, throwing away a defective product, or deleting posts about the accident can hand the defense the same arguments described above. The analysis also turns heavily on timing. A written preservation demand sent in the first week creates a clear record that the other side knew what to keep. Once that record exists, a later loss looks far less like an accident and far more like a choice, which can push the case from a permissive inference toward the stronger statutory presumption.

Protect the Proof Before It Is Gone

At Mainor Ellis Injury Lawyers, we send preservation demands early and follow up on them, because the most important evidence in a case is often on a countdown no one announces.
