Federal Rule of Evidence 702 Expert Reports & Joint Statements
Experts instructed in federal and state courts litigation owe paramount duties to the court under Federal Rule of Evidence 702 and Daubert. Reports must identify instructions, materials reviewed, key assumptions, and limitations - with fair exposition where reasonable experts disagree.
Joint meetings and joint statements isolate areas of agreement and disagreement on methodology, datasets, and quantum ranges, narrowing trial issues efficiently.
| Report element | Why it matters | Common pitfall |
|---|---|---|
| Instructions scope | Defines the question answered | Over-broad remit |
| Data lineage | Reproducible spreadsheets | Black-box models |
| Alternative assumptions | Daubert-compliant range disclosure | False precision |
| Joint statement | Agreed facts vs opinions | Late surprises at trial |
