The facts
- Cost
- Free. The Federal Rules of Evidence are public and are published in full, with notes, by Cornell's Legal Information Institute.Figure read 2026-09-12 from www.law.cornell.edu/rules/fre/rule_702
- Prerequisites
- Legal training. This is primary source material, not a course.
- Format
- Rule text with committee notes. Rule 702, as amended effective 1 December 2023, now requires the proponent to demonstrate to the court that it is more likely than not that each reliability condition is met, and that the expert's opinion reflects a reliable application of the principles and methods to the facts. Rule 901(b)(9) admits evidence describing a process or system and showing that it produces an accurate result. Rules 902(13) and 902(14) allow self-authentication of records generated by an electronic process and of data copied from a device, each on a qualified person's certification meeting Rule 902(11) requirements, including its notice obligations.

Strengths
- Free, authoritative and short. These four provisions govern whether the forensic work in your case is admitted at all.
- The 2023 amendment to Rule 702 is the single most important recent change for challenging an expert, because it puts reliability squarely at admissibility rather than weight.
- Rules 902(13) and (14) are what let you get electronic records in without a live witness — and what let you object when the certification is thin.
- Reading the rules is also how you work out which training an examiner you are retaining actually needs.
Limitations
- Federal rules only. State evidence codes differ, and a Frye jurisdiction does not apply the Daubert framework at all.
- Rule text is not instruction: it tells you the standard, not how to build or attack a record under it.
- No CLE credit, and no credential.
- We verified this text against Cornell's LII. We could not retrieve the uscourts.gov transmittal page for the December 2023 amendment package, so cross-check the official source before quoting it in a brief.
