A presumption of law and from the law — a conclusive presumption.

Explanation

Certain presumptions are so firmly established in law that no contrary evidence is permitted to rebut them; the law treats the presumed fact as conclusively established.

Where this applies

• There's a legal presumption being used against me that I'm told I can't fight.
• The court says this presumption is conclusive and I'm not allowed to present contrary evidence.
• A presumption of law is being treated as absolute and unchallengeable.
