scientific testimony
Technical courtroom statements
Scientific testimony is expert evidence presented in legal proceedings, where specialists explain technical findings to judges and juries.
Unlike ordinary witness testimony about observed events, scientific testimony interprets data, methodology, or conclusions requiring specialized knowledge: The forensic scientist's testimony linked the DNA to the defendant.
Courts apply standards to ensure such testimony is reliable and based on sound science.
