• Rule 404(b) notice amended Dec 1 2020 — prosecutor must provide written notice of permitted purpose and reasoning.
• Rule 702 amended Dec 1 2023 — clarifies preponderance standard for admissibility, expert opinion must reflect reliable application.
• Rule 107 Illustrative Aids added effective Dec 1 2024 — aids that assist jury understanding, ordinarily not sent to deliberation room absent consent/good cause. Distinct from Rule 1006 summaries which ARE substantive evidence.
• Rule 106 remainder amended Dec 1 2023 — completing statement fairness.

The Core Gatekeeping Architecture

Systematic admissibility: Identify item → proponent → purpose → relevance (401/402) → 403 balancing → policy exclusions → character/Habit → witnesses/opinions/impeachment → hearsay layers → confrontation → privilege → authentication → best evidence → limiting instructions → preservation → definitive ruling.

“Identify the item, identify the purpose, apply every independent rule, finish with a ruling.”

Steps 1–5: Item, Proponent, Purpose, Relevance & Rule 403

Step 1 Item: Classify evidence before naming a rule.
Step 2 Proponent: Plaintiff/prosecution/defense alters character & confrontation analysis.
Step 3 Purpose: “Offered to prove ___.”
Step 4 Relevance: Rule 401 tendency + 402 general admissibility.
Step 5 Rule 403: Probative substantially outweighed by unfair prejudice — damaging ≠ unfair.

Steps 6–11: Policy, Character, Habit, Witnesses

Step 6 Policy: 407 remedial, 408 compromise, 409 medical offers, 410 pleas, 411 insurance, 412 sexual behavior.
Step 7 404(a) vs 404(b): Propensity prohibited vs MIMIC nonpropensity (motive, intent, plan, absence of accident) — explain chain, Rule 105 limiting instruction, 403 balancing, and 404(b)(3) notice (2020 amendment).
Step 8 406 Habit: Regular, specific, semi-automatic response to repeated situation vs general disposition.
Step 9 Foundation: 602 personal knowledge, 603 oath, leading, speculation.
Step 10 Opinions: 701 lay perception vs 702 Daubert/Kumho (2023 amendment: preponderance, sufficient facts, reliable principles/methods reliably applied). 703 hearsay reliance.
Step 11 Impeachment: Bias, 613 prior inconsistent, 608 untruthfulness, 609 convictions, contradiction, sensory defects.

Steps 12–14: Hearsay & Confrontation

Step 12: Isolate declarant, timing, assertion, purpose.

Step 13 Truth: 801(d)(1) prior witness (requires oath at prior proceeding for 801(d)(1)(A)), 801(d)(2) opposing party (no personal knowledge required), 803 (availability immaterial), 804 (unavailability required), 807 residual, 805 every layer needs basis!

Step 14 Confrontation: Criminal case — hearsay exception ≠ 6th Amendment satisfied. Testimonial hearsay for truth against accused requires declarant testimony + cross or unavailability + prior cross (unless forfeiture). Forensic reports prepared for prosecution are testimonial (Melendez-Diaz 2009, Bullcoming 2011).

Steps 15–20: Privilege, Authentication, Best Evidence & Ruling

15 Privilege: Protects communications, not facts; check confidentiality, waiver, crime-fraud.
16 Authentication: 901 threshold; 902 self-auth; digital attribution; chain of custody.
17 Best Evidence: 1001–1008 applies ONLY when proving contents of writing/recording/photo. Distinguish 1006 voluminous summary (substantive, goes to jury) vs 107 illustrative aid (Dec 1 2024, non-substantive, ordinarily not to deliberations).
18 Limiting/Conditional: 105 limiting use; 104(b) conditional relevance.
19 Preservation: 103(a)(1) timely specific objection; 103(a)(2) offer of proof.
20 Ruling: Definitive: Admitted, Excluded, Admitted only for impeachment with limiting instruction, Redacted, Conditionally admitted.

Chronology

1. Before Trial: Motions in limine, Daubert, 404(b) notice (2020), authentication stipulations, privilege.

2. Case-in-Chief: Direct, exhibits, expert reliability, cross, impeachment.

3. Defense: Party identity alters character/constitutional analysis.

4. Rebuttal: Respond to new matters, not replay.

5. Closing: Reasonable inferences from admitted evidence. Rule 107 aids assist argument, ordinarily do NOT enter deliberations.

Common Traps

• Damaging ≠ unfair prejudice under 403.

• Identify relevance before 403.

• Name specific 404(b) purpose + chain, not just “404(b).”

• Habit (406) vs character.

• 407 feasibility only if genuinely disputed.

• No speculation about unobserved mental states.

• Refreshing (612) vs recorded recollection (803(5)).

• Check truth purpose before calling hearsay.

• Opposing-party (801(d)(2)) vs statement against interest (804(b)(3)).

• 803 needs no unavailability; 804 does.

• Hearsay exception ≠ Confrontation satisfied.

• Privilege protects communications, not facts.

• Original only when proving contents.

• 1006 summary (substantive) vs 107 illustrative aid (2024).

• Always finish with definitive ruling!
