An oath has in it three component parts — truth, justice, and judgment: truth is requisite in the party swearing, justice and judgment in the judge administering the oath.

Explanation

The oath binds both the swearer and the officer — the swearer must speak truth, and the judge must administer the oath justly and with sound judgment.

Where this applies

• A witness lied under oath — both the witness and the judge who administered the oath have duties.
• The oath-taker must speak truth and the judge administering it must do so justly.
