In civil cases, what does "expert evidence" refer to?

Expert evidence refers specifically to testimony provided by individuals who possess specialized knowledge or expertise relevant to the case at hand. This type of evidence is essential in civil cases where the issues being litigated require understanding of complex subject matter that is beyond the knowledge of an average juror.

For instance, in cases involving medical malpractice, a medical expert can provide insights into standards of care and whether these were adhered to. Similarly, in technical disputes, an engineer might be called upon to explain complex engineering principles. The credentials, experience, and particular expertise of these witnesses allow them to offer informed opinions that can help the court understand the intricacies of the subject matter involved.

The other options do not accurately define what constitutes expert evidence. General opinions from the public or witness testimonials without specialized knowledge do not provide the necessary depth of insight intended by expert evidence. Data provided by the court does not fall under the category of evidence given by expert witnesses, as it pertains to information rather than the interpretative expertise that expert witnesses provide. Thus, the choice that correctly identifies expert evidence is the one that highlights testimony from individuals with relevant specialized knowledge.
