Expert Testimony Summarization

Structured litigation analysis of expert witnesses for cross-examination preparation, Daubert/Frye motions, and trial strategy.

Required Inputs

1. Expert report(s) — initial, rebuttal, supplemental
2. Deposition transcript(s) — page/line numbers intact
3. Curriculum vitae
4. Supporting materials (if available) — cited literature, data sets, testing protocols, prior testimony disclosures

Workflow

1. Expert Profile

Capture: name/title, retaining party, compensation disclosed, prior testimony history (case count + plaintiff-vs-defense ratio), areas of claimed expertise.

2. Opinions Inventory

For each opinion:

• Ultimate conclusion — verbatim or close paraphrase with source cite (report section or depo page:line)
• Supporting sub-opinions — numbered
• Source citation — report section or depo page:line

3. Methodology Analysis

For each methodology, assess:

• Technique/framework used
• Peer-reviewed (Yes / No / Partial)
• Industry standard (Yes / No)
• Novel or proprietary
• Independently replicable
• Error rate disclosed

4. Factual Basis

• Documents and data sources relied upon
• Independent verification performed vs. assumed facts
• Key assumptions — flag unverified or contested assumptions

5. Strengths & Weaknesses

Strengths — credentials match opinion subject, peer-reviewed methodology, internal consistency, independent testing/analysis.

Weaknesses checklist:

• Opinions exceed CV-supported expertise
• Unsupported or contested assumptions
• Methodology not peer-reviewed or generally accepted
• Reliance on inadmissible or unreliable data
• Inconsistencies with published literature
• Inconsistencies with expert's prior testimony or publications
• Advocacy bias indicators (extreme retention ratio, hired-gun history)
