written statements;
documents;
maps, plans and photographs;
sound and video recordings;,
business records;
certificates;
material objects, such as parts of machinery.
In order for this evidence to be admitted, you must follow the correct rules and procedures. Some documents may 'speak for themselves'; others may need to be presented by a witness before becoming receivable in evidence.
The collection of documentary and real evidence ("Physical evidence") is dealt with in the Investigation Stage of the Enforcement Guide in the `Collecting Physical Evidence' section.
