Late Objection to Irrelevant Footage
Flora Ford sued Fulton Shipping after a cargo mishap. More than thirty days before trial the parties exchanged pretrial disclosures. Fulton Shipping failed to object within fourteen days to a dashcam clip that showed only routine port activity unrelated to the mishap. At the final conference Fulton Shipping raised a relevance objection. The court permitted the objection because it rested on FRE 402.
Bias Evidence Tied to Witness Motive
Freya Freeman testified for the prosecution against Fernando Farrell. Defense counsel sought to introduce proof that Freeman belonged to the same gang as the defendant and therefore had a motive to lie. The evidence made Freeman's credibility less probable and therefore satisfied the threshold for admission.

Prior Conviction Details Versus Stipulation
Francisco Frost faced a felon-in-possession charge. The government offered the full judgment of his earlier robbery conviction. Frost offered to stipulate to the fact of conviction.

Other Stolen Goods to Show Knowledge

Common questions
Frequently Asked
5
What is the basic test for relevance under FRE 402?+
Evidence is relevant if it has any tendency to make a fact of consequence more or less probable. Relevant evidence is admissible unless another rule or constitutional provision excludes it. Irrelevant evidence is never admissible.
Does a dramatic demonstrative exhibit automatically satisfy relevance?+
No. A demonstrative aid must still be tethered to a fact of consequence. A generic marketing reel offered only to evoke emotion fails the test even if vivid.
When may a party raise a pure relevance objection after the pretrial disclosure deadline?+
Objections based on FRE 402 may be raised at trial even if not listed within the fourteen-day window. All other objections to deposition designations and exhibits are waived absent good cause.
Is evidence of a party's unrelated prior conduct relevant to due care in a negligence case?+
No. A parking ticket issued months earlier does not tend to prove or disprove whether brakes were defective or properly repaired. Such evidence fails the relevance threshold.
How does conditional relevance under Rule 104(b) interact with FRE 402?+
When relevance depends on a preliminary fact, the proponent must introduce evidence sufficient for a reasonable jury to find that fact exists. The assistant's remark about cracked bats satisfied this standard because the assistant handled the equipment during the season.
