Common questions

What happens if an exhibit number is reused or duplicated by mistake?+

It breaks the continuity the numbering system is meant to guarantee, since two items sharing a number can no longer be distinguished in the exhibit log or later testimony, which can be challenged as a chain-of-custody defect.

Does an exhibit number replace the need for a written description of the item?+

No. The number is a reference code, not a substitute for the description of the item, its location, and the circumstances of recovery, all of which must still be recorded in the scene notes and exhibit log.
