Competence to Testify

Competence to Testify in Court

Introduction to Competence to Testify

• Courts have a long-standing principle that a person may not testify if they:

  • Cannot remember or accurately report what they saw.

  • Cannot grasp the importance of depicting information accurately.

Distinction from Other Competencies

• Competence to testify is unique because it impacts more than just the defendant.

  • It can be evaluated for victims and witnesses, essentially anyone who will testify in a court case.

  • It arises in both civil and criminal trials.

  • In criminal court, one's competence to plead guilty can be questioned, but this does not apply in civil trials, marking another difference.

Legal Requirements: Federal Rules of Evidence Rule $601$

• Concerns about a person's competency to testify are addressed by the fact finder, usually the judge, who determines the truthfulness of information.

• The Federal Rules of Evidence added Rule $601$ in $1975$, which states: "every person is competent to be a witness unless their testimony is irrelevant or likely to mislead the fact finder, or the person is unable or unwilling to promise to testify truthfully."

Modern Trend and Exceptions

• The modern legal trend presumes that everyone is competent to testify unless there is a specific reason to believe otherwise.

• Exception: Someone testifying as a victim of abuse is considered "irrebuttably competent," meaning their testimony will not be questioned on competence grounds.

Five Capacities of Competence to Testify

• The criteria for competence to testify include five fundamental capacities. It is presumed that each area only requires a minimum capacity, making it rare for a person's competency to be questioned.

I. Ability to Observe an Event

• The capacity to observe is sufficient unless:

  • A child or a person with developmental disabilities has a hearing or vision impairment, which could prevent an accurate recollection of events.

  • A person lacks the ability to process all events, similar to how children process information differently than adults.

II. Ability to Remember the Event (Memory and Suggestibility Prong)

• The capacity to remember is as critical as the capacity to observe.

• Most research in this area originated and has been conducted on children.

• Inquiries often distinguish between two types of memory:

  • Recognition memory: Involves identifying information from given choices (e.g., multiple-choice questions).

  • Recall memory: Involves independently recollecting and stating what happened without prompts (e.g., asking "what happened?").

III. Ability to Communicate What Happened

• This capacity is essential because even if an event was observed and remembered, the court cannot understand what transpired if the person cannot clearly articulate it.

• A person's ability to form ideas and concepts regarding the event is crucial for effective communication.

IV. Ability to Tell the Difference Between True and False

V. Ability to Understand the Obligation to Tell the Truth in Court (Moral Development Prong)

• Together, these capacities relate to the moral development prong, focusing on the duty to tell the truth.

• If a witness can recall an event, it is paramount that they do so truthfully.

• Courts emphasize the ability to:

  • Differentiate between truth and falsehood.

  • Comprehend the fundamental duty to tell the truth.

  • Understand the potential consequences of failing to tell the truth.

Psychological Research: Categories for Testimonial Capacity Evaluation

• Four categories of individuals are most likely to trigger a testimonial capacity evaluation:

  • $1$. Children: Their cognitive processing differs from adults, leading to questions about their understanding of testimony.

  • $2$. Individuals with intellectual and developmental disabilities: May have challenges with observation, memory, communication, or understanding truth.

  • $3$. Individuals with mental illnesses: Certain conditions might affect their ability to accurately perceive, remember, or report events.

  • $4$. Individuals with substance abuse issues: Substance use can impair cognitive functions relevant to testimonial competence.

Guidelines for Evaluation

• Courts generally show reluctance to order psychological evaluations of witnesses, viewing it as an invasion of privacy.

• However, such evaluations will be ordered if deemed necessary.

• If an evaluation is conducted, it should primarily focus on the first four capacities:

  • Observation

  • Memory

  • Communication

  • The ability to distinguish between what is true and what is false

Assessing Testimonial Skills

• Assessing Observational Skills: Can be done by asking the individual to recall simple details related to an event.

• Assessing Memory Skills: Involves asking simple questions about both recent and long-past events.

• Assessing Communication Skills: Accomplished by having the witness recall events and evaluating how effectively they describe aspects like time, space, and other details. Recalling the event multiple times may also reveal communication consistency.

• Assessing Understanding and Commitment to Tell the Truth: This can be evaluated by asking direct questions such as:

  • "What does telling the truth mean to you?"

  • "Why is telling the truth important?"

  • The responses help determine their grasp of the significance of truthfulness.

• An optional supplementary video discussing the specifics of competence to testify in regards to children is available. It is approximately $10$ minutes and $46$ seconds long and provides a deeper dive into evaluating child witnesses, building on the initial research focus on children mentioned in this presentation.
