In dubio pro reo

 Meaning: When in doubt, for the accused.
Explanation: A criminal law rule requiring that if evidence leaves reasonable doubt, the accused should be acquitted. It protects against wrongful convictions and enshrines the presumption of innocence. Courts use it when evidence is balanced or unclear.
Example: If witness accounts of an event contradict and no forensic evidence resolves the conflict, a court may acquit under in dubio pro reo.
