Identity ordinarily connotes exactness.

Explanation

(English-origin maxim.) Proof of identity requires exactness — invoke this maxim to challenge an identification that rests on approximate or general similarities rather than precise correspondence.

Where this applies

• A witness identifies the suspect as approximately six feet tall with dark hair, but the defense argues that such a vague description fails the standard of exactness required for positive identification.
• A bank refuses to release funds because the name on the withdrawal slip is spelled slightly differently from the account holder's name, insisting that identity requires precision.
• A forensic analyst testifies that a partial fingerprint with only seven matching points is insufficient because identity demands exactness, not mere similarity.
