Federal and State Rules of Evidence
Federal and state rules of evidence serve as the legal framework that governs the admissibility of forensic evidence in court proceedings. These rules vary between jurisdictions but generally aim to ensure that only relevant, reliable, and properly obtained evidence is presented.
At the federal level, the Federal Rules of Evidence (FRE) provide a standardized set of guidelines that courts follow nationwide. These rules address issues such as relevance (Rule 401), the testing of scientific methods (Rule 702), and the exclusion of evidence obtained unlawfully or through unreliable techniques. State rules often mirror the FRE but may include variations tailored to specific legal contexts within each state.
Legal standards like the Daubert standard further influence the admissibility of forensic evidence, emphasizing scientific reliability and peer review. Overall, the interplay between federal and state evidence rules ensures that forensic evidence meets established legal criteria, maintaining fairness and integrity in judicial proceedings.
The Daubert Standard and Scientific Reliability
