In Brief: Expert Evidence

OJEN In Brief resources are designed to provide high school students with an introduction to basic legal concepts. Each resource includes a short lesson plan for the teacher; a plain language description of the legal topic; and activities that provide students with the opportunity to apply their knowledge of the topic.

This handout provides an introduction to the law on expert evidence, including what expert evidence is and what makes someone an expert. Students are also introduced to the Mohan test which is the legal test for determining whether an expert opinion should be admitted into evidence. Related classroom activities encourage students to apply their knowledge to discussion-based scenarios and case studies.
