RULE 703
BASES OF OPINION TESTIMONY BY EXPERTS

The facts or data in the particular case upon which an expert bases an opinion or inference may be those perceived by or made known to the expert at or before the hearing. If of a type reasonably relied upon by experts in the particular field in forming opinions or inferences upon the subject, the facts or data need not be admissible in evidence.

Note:

The rule is identical to the federal rule and former Rule 43(m)(2), SCRCP, and former Rule 24(b), SCRCrimP. This rule makes it clear that an expert may rely on facts or data in giving an opinion which are not admitted into evidence.
