Relevance > Exclusion of Relevant Evidence > Discretionary exclusion
In a federal contract trial, Naomi wants to impeach a witness by showing that the witness has been hostile toward her for years. Naomi offers to call seven witnesses and introduce records, emails, and accountant testimony about a separate business dispute between Naomi and the witness. The judge allows Naomi to ask the witness directly about hostility but excludes the seven-witness side presentation under Rule 403. Was the exclusion proper?
01 Start with the judge's compromise.
02 Notice that bias can be tested directly.
03 Separate bias relevance from proof volume.
04 Reject the idea that bias evidence can never be limited.
05 Reject the idea that credibility evidence escapes Rule 403.
06 Reject the character-evidence label.
07 Use Rule 403 to control the collateral mini-trial.
08 Choose C.
A / trap
No, because bias evidence can never be limited.
A overstates the bias rule. Bias evidence is important, but the method and volume of proof can still be controlled.
B / trap
No, because once evidence is relevant to credibility, Rule 403 does not apply.
B gives credibility evidence immunity it does not have. Rule 403 still applies to credibility proof.
C / correct
Yes, because the court may allow targeted bias inquiry while excluding a collateral mini-trial whose time and confusion substantially outweigh added probative value.
C preserves both ideas. The judge lets Naomi ask about hostility but blocks a sprawling side dispute with limited additional value.
D / trap
Yes, but only because bias evidence is always inadmissible character evidence.
D reaches the yes result for the wrong reason. Bias is not barred character evidence; the problem is collateral proof that wastes time and confuses the trial.
Red axis: A strong impeachment purpose does not erase Rule 403 control over cumulative or confusing collateral proof.
Purple profile: The traps treat bias as either untouchable, immune from Rule 403, or wrongly reclassified as character evidence.
Blue signal: The judge allowed direct hostility questions but excluded seven witnesses and records about a separate dispute.
Orange repair: Student habit to repair: thinking relevance to credibility automatically permits every supporting side presentation.
Gold Key / GK-EVIDENCE-403-BIAS-MINI-TRIAL-01
Bias impeachment is relevant, but Rule 403 lets the judge limit collateral proof that adds little beyond a direct bias inquiry while consuming time or confusing the issues.
Silver Key / SK-EVIDENCE-PROOF-METHOD-01
Separate whether a fact may be explored from how much proof the court must allow to prove it.
Trap Key / TK-EVIDENCE-CREDIBILITY-NOT-403-IMMUNE
Credibility evidence is not immune from Rule 403 just because it attacks or supports a witness.
01 Name the purpose: bias impeachment.
02 Confirm the judge allowed a direct question about hostility.
03 Spot the proposed seven-witness side presentation.
04 Treat the side dispute as collateral proof.
05 Reject bias-is-untouchable language.
06 Reject credibility immunity from Rule 403.
07 Reject the character-evidence reason.
08 Pick C.
Bias Scope
A party may ask a witness directly about hostility. Must the court also allow seven witnesses to prove a separate dispute?
No. Rule 403 may limit collateral proof that adds little and creates delay or confusion.
Credibility Control
Does evidence become immune from Rule 403 because it relates to witness credibility?
No. Credibility evidence remains subject to Rule 403.
Wrong Reason
Why is it wrong to say bias evidence is always inadmissible character evidence?
Bias is a proper impeachment purpose; the issue is excessive collateral proof, not character inadmissibility.
