Federal Rules of Evidence
Introduction
Transition from the demanding 'general acceptance' standard set by Frye v. United States (1923) to the more structured framework of the Federal Rules of Evidence (FRE).
Historical context prior to the 20th century: laws were primarily based on common law, or decisional law, where judicial rulings established precedent (stare decisis).
Common law evidence rules were uncodified, often leading to inconsistency across jurisdictions and continued reliance on these uncodified concepts even post-Frye.
Codification of Evidence Rules
Process of Establishment: The push for standardized federal law led to the formation of an advisory committee established circa 1965 by the Judicial Conference of the United States.
Composition: Included leading US lawyers, judges, and legal scholars dedicated to modernizing evidentiary procedure.
Goal: To develop a uniform, comprehensive set of rules governing evidence in federal courts, moving away from fragmented common law.
Enactment: The proposed rules underwent extensive review and modification, including Congressional consideration mandated by statute.
Emergence of the Federal Rules of Evidence (Public Law 93-595), which became law and effective in 1975.
Note: While earlier drafts were approved (e.g., 1973 by the Supreme Court), Congress asserted authority and the final, adopted version became effective in 1975, marking a significant transition point in federal jurisprudence.
Overview of Federal Rules of Evidence (FRE)
Purpose: To govern the admissibility of evidence and regulate procedural fairness in federal trials, applicable to both civil and criminal cases.
Applicability:
Federal courts (District Courts, Courts of Appeals, Supreme Court) are required to follow the FRE.
State courts maintain sovereignty; they may choose to follow the FRE, adapt state-specific evidence codes, or continue using standards like Frye or Daubert.
Structure: The FRE contains 11 comprehensive articles covering different aspects of evidence. Key areas frequently studied include:
General provisions
Relevancy and Its Limits (Article IV).
Witnesses (Article VI), addressing competency and impeachment.
Opinions and expert testimony (Article VII), crucial for scientific evidence.
Objective of FRE: To secure fairness in administration, eliminate unjustifiable expense and delay, and promote the growth and development of the law of evidence to the end that the truth may be ascertained and proceedings justly determined.
Key Themes and Objectives of FRE
Designed to:
Promote fair judicial proceedings by providing clear, uniform standards.
Reduce financial burdens and delays in the legal process by streamlining evidentiary disputes.
Enhance the predictability and development of the law of evidence, aiding in the just resolution of disputes.
Limitations:
The FRE does not supersede all prior common law; rather, it codified and modified central principles.
Aimed at assisting legal professionals and triers of fact (judges and jury) in resolving disputes by providing necessary tools.
Flexibility: Courts maintain interpretive discretion, allowing them to adapt evidentiary laws to various legal circumstances rather than rigidly discarding established common laws, especially where the FRE is silent.
Introduction to Specific Rules of Evidence
Rule 104: Preliminary Questions
This rule specifies how the court determines questions of admissibility.
Rule 104(a): Admissibility Generally: The judge determines qualifications of expert witnesses and the admissibility of evidence. In deciding these preliminary questions, the judge is not bound by the FRE (except those concerning privilege).
Rule 104(b): Relevance That Depends on a Fact (Conditional Relevancy): Evidence may be admitted if sufficient evidence is introduced to support a finding that the related fact exists.
Criteria for admissibility may include considerations of privilege (e.g., doctor-patient, priest-parishioner communications), which the judge must decide immediately.
Prior bad acts (e.g., crimes or wrongs) may be conditionally allowed by the judge under 104(b) if later proof links them to establish motive, identity, or absence of mistake.
Risks of jury prejudice are high with the introduction of prior bad acts regarding whether the jury can properly limit its use to non-propensity issues.
Relevancy of Evidence
Rules 401 and 402: Establish the foundation for what evidence courts will consider.
Rule 401: Test for Relevant Evidence: Defines relevant evidence with a low threshold, often called the "any tendency" test.
A) Has any tendency to make a fact more or less probable than it would be without the evidence; and/or
B) The fact is of consequence in determining the action (i.e., material to the dispute).
Rule 402: General Admissibility of Relevant Evidence: Relevant evidence is generally admissible unless specifically excluded by the US Constitution, a federal statute, the FRE, or other Supreme Court rules. Irrelevant evidence is inadmissible.
Example:
Testimony regarding a full moon's presence on the night of a crime can be relevant if it impacts visibility, thus aiding or hindering the crime's commission, fulfilling the "tendency" requirement.
Distinction made between evidence that is relevant (meets 401) but still not admissible in court (excluded by 403 or other rules).
Admissibility and Exclusion of Evidence
Rule 403: Excluding Relevant Evidence for Prejudice, Confusion, Waste of Time, or Other Reasons: Establishes the crucial balancing test for the exclusion of relevant evidence.
The court may exclude relevant evidence if its probative value is substantially outweighed by a danger of:
Unfair prejudice (arousing emotional response or bias against the party).
Confusion of issues (leading the jury down irrelevant paths).
Misleading the jury (suggesting scientific certainty where none exists).
Undue delay, wasting court time, or needlessly presenting cumulative evidence.
Discussion on limited admissibility and the judge's ability to instruct juries to disregard evidence for certain purposes (a complexity in ensuring proper jury perception).
Rule 404: Character Evidence; Crimes or Other Acts: Establishes limitations on introducing evidence of a person’s prior bad acts or character.
In civil or criminal cases, evidence of character or character trait is generally inadmissible to prove that on a particular occasion the person acted in accordance with the character or trait (prohibition on propensity evidence).
Can only be used for specific non-propensity purposes (M.I.M.I.C.): motive, intent, absence of mistake, identity, or common plan/scheme (opportunity is also frequently included).
Example discussed: In a trial for the murder of a prostitute, it is not permissible to introduce the victim's history of prostitution solely to argue that she was inherently susceptible to dangerous situations, as it constitutes unfair character/propensity prejudice under Rule 404.
Opinion and Expert Testimony
Rules 701 and 702: Address opinions and expert testimony specificities, crucial parts of modern litigation.
Rule 701: Opinion Testimony by Lay Witnesses: Non-expert witnesses can provide opinion testimony only if it is rationally based on the witness's perception (e.g., commenting on observable facts like the color of curtains, speed of a vehicle, or apparent emotional state) and is not based on scientific, technical, or specialized knowledge.
Rule 702: Testimony by Expert Witnesses: The judge serves as the gatekeeper, ensuring the testimony rests on a reliable foundation and is relevant to the facts in issue.
An expert witness may testify if:
The expert’s scientific, technical, or other specialized knowledge will help the trier of fact understand the evidence or determine a fact in issue.
The testimony is based on sufficient facts or data.
The testimony is the product of reliable principles and methods.
The expert has reliably applied the principles and methods to the facts of the case.
Qualification assessment typically occurs during a voir dire examination conducted by counsel, often outside the presence of the jury. Challenges to expert testimony and qualifications can be made by opposing counsel based on these foundational requirements.
Basis of Expert Testimony and Challenges
Rule 703: Bases of an Expert’s Opinion Testimony: Concerns the underlying information an expert relies upon.
Experts can base opinions on facts or data they have personally observed or been made aware of (e.g., physical examination, review of records).
Significantly, experts can be queried about the basis for their opinions, and they may rely on inadmissible facts or data if experts in the particular field would reasonably rely on those kinds of facts or data. If the facts are inadmissible, they cannot be disclosed to the jury unless their probative value supporting the opinion substantially outweighs their prejudicial effect.
Rule 706: Court-Appointed Experts: Addresses the inherent difficulty judges face in assessing novel or complex scientific testimony, often described as judges acting as amateur scientists.
To mitigate bias or confusion, the court may, upon motion of any party or its own motion, appoint an expert witness to testify.
Potential solutions include appointing neutral experts agreeable to both sides, or allowing parties to propose experts and letting the court select the most neutral and qualified one.
Evolution of Evidentiary Standards
Historical comparison between Frye and FRE:
Frye v. United States (1923) established an initial, stringent standard for determining scientific evidence admissibility based solely on 'general acceptance' within the relevant scientific community.
The FRE (1975), specifically Rule 702, marked a move toward a more flexible framework focusing on relevance and reliability, evolving the standards much further than the Frye test.
The convergence between Frye, the later Daubert standard (which interprets FRE Rule 702), and common law evidentiary rules reflects a progression in legal standards over time, prioritizing reliability and methodological soundness.
Transition to the Daubert Case
The framework provided by the FRE, particularly Article VII, laid the groundwork for the paradigm-shifting ruling in the Daubert v. Merrell Dow Pharmaceuticals case (1993), which further defined and solidified the judge's "gatekeeper" role regarding scientific and expert testimony.
