Intro to Forensic Case Law - Precedent Power Play

  • Case law: Law established by judicial decisions in past cases (precedents).
  • Vital in forensics: Guides admissibility, interpretation, and impact of scientific evidence in court.
  • Binding authority: Higher court rulings obligate lower courts in the same jurisdiction.
  • Persuasive authority: Decisions from other jurisdictions can influence, but aren't mandatory.
  • Dynamic: Evolves with new scientific methods and legal interpretations.

⭐ The principle of stare decisis (to stand by decided cases) is fundamental, ensuring consistency and predictability in legal judgments concerning forensic evidence.

  • Ensures fairness and uniformity in applying legal principles to forensic findings across cases.
