SPOT issues: which concerns whether the expert's opinion has sufficient factual basis?

• A. Proper Subject
• B. Proper Person
• C. Proper Opinion
• D. Proper Testimony

Answer: (C)

The key idea here is whether the expert’s conclusion is grounded in a solid factual foundation. In SPOT, the Proper Opinion element focuses on the adequacy of the data or facts the expert relied on and whether the relevant principles and methods were applied reliably to those facts. A valid expert opinion isn’t just a guess; it must be supported by sufficient underlying information—data, observations, tests, or records—and the methods used to reach the conclusion must be applied properly. For example, if an engineering expert testifies that a structure failed due to corrosion, the opinion is acceptable only if it rests on concrete data like inspection reports, material tests, and analyses using accepted methods. If those facts aren’t there, the opinion lacks the necessary factual basis. The other SPOT elements cover different safeguards: proper subject ensures the topic is admissible, proper person checks qualifications, and proper testimony examines whether the reasoning and presentation meet admissibility standards.
