b. Selected Legal Precedents

Selected Legal Precedents in Forensic Law
Legal precedents shape the landscape of forensic law, establishing guidelines and principles for the admissibility and use of forensic evidence in court. The following are selected legal precedents that have had a significant impact on the intersection of law and forensic science:

  1. Daubert v. Merrell Dow Pharmaceuticals, Inc. (1993):
    Background: This landmark U.S. Supreme Court case established the Daubert Standard for the admissibility of scientific evidence. The case involved birth defects allegedly caused by a drug, and the court ruled that judges should act as gatekeepers, ensuring that expert testimony is based on scientifically valid principles.
    Impact: Daubert significantly influenced the criteria for admitting expert testimony, emphasizing the need for scientific validity, peer review, and error rates.
  2. Frye v. United States (1923):
    Background: In this early 20th-century case, the court introduced the Frye Standard, requiring that scientific evidence must have gained general acceptance in the relevant scientific community to be admissible.
    Impact: Frye had a lasting impact on the admissibility of novel scientific techniques, shaping the approach to expert testimony for decades. While some jurisdictions have moved away from the Frye Standard, its influence is still felt in legal discourse.
  3. Melendez-Diaz v. Massachusetts (2009):
    Background: The U.S. Supreme Court ruled that forensic analysts must be available for cross-examination in criminal trials. The case centered on the admissibility of certificates of analysis in drug cases without the presence of the analyst.
    Impact: Melendez-Diaz underscored the importance of the confrontation clause of the Sixth Amendment and the right of defendants to cross-examine the individuals producing forensic reports.
  4. Missouri v. McNeely (2013):
    Background: The Supreme Court ruled that the natural dissipation of alcohol in the bloodstream does not create a per se exigency that justifies a warrantless blood test for DUI cases.
    Impact: McNeely reinforced the Fourth Amendment protections against unreasonable searches and seizures, emphasizing the need for a case-by-case analysis of exigency in blood-alcohol testing.
  5. People v. Castro (1985):
    Background: In this California case, DNA evidence was used for the first time in a criminal trial. The court allowed DNA evidence to be admitted, marking a pivotal moment in the acceptance of DNA profiling in legal proceedings.
    Impact: Castro played a crucial role in establishing the admissibility of DNA evidence, paving the way for its widespread use in subsequent criminal cases.
  6. R v. Cunningham (1957):
    Background: This British case is notable for the first use of forensic odontology in a criminal trial. Bite mark analysis was presented as evidence to link the accused to a crime scene.
    Impact: Cunningham set a precedent for the use of bite mark analysis in legal proceedings, influencing the acceptance of this forensic technique in subsequent cases.
  7. People v. Jennings (2007):
    Background: The case addressed the admissibility of firearm and toolmark identification evidence. The court emphasized the importance of establishing scientific reliability in such forensic evidence.
    Impact: Jennings contributed to the ongoing discussion about the scientific basis of forensic disciplines, particularly in the context of firearm and toolmark analysis.

These selected legal precedents reflect pivotal moments in the evolution of forensic law, influencing the admissibility and standards for various types of forensic evidence in legal proceedings. Each case has contributed to the ongoing refinement of the intersection between forensic science and the legal system.
