Lesson 30: Presentation of Evidence

Welcome to Lesson 30 of our instructable on The Trial Process in criminal procedure. In this lesson, we will explore how evidence is presented during a criminal trial, the rules that govern the admissibility of evidence, and the roles of the various parties involved in presenting evidence.

What is Evidence?

Evidence is any type of proof legally presented at trial through witnesses, records, or exhibits to convince the judge or jury of the facts in the case. Evidence can be classified into various types including:

  • Direct Evidence
  • Circumstantial Evidence
  • Real Evidence
  • Documentary Evidence
  • Testimonial Evidence

Types of Evidence

Understanding the different types of evidence is crucial for both prosecutors and defense attorneys. Here's a simple diagram to illustrate the types of evidence:

Rules Governing Admissibility of Evidence

Not all evidence can be presented in court. The admissibility of evidence is governed by rules designed to ensure fairness and reliability in the judicial process. These rules include:

  • Relevance: Evidence must be relevant to the case.
  • Materiality: Evidence must have a significant impact on the case.
  • Competency: Evidence must come from a competent source.
  • Hearsay Rule: Hearsay evidence is generally inadmissible unless it falls under an exception.

Role of the Judge and Jury

The judge plays a crucial role in determining the admissibility of evidence, while the jury evaluates its weight and credibility. The process can be illustrated as follows:
