The negation of a conclusion is error in law.

Explanation

To deny a conclusion that follows necessarily from established premises is itself a legal error; the law demands that reasoning be carried to its logical end.

Where this applies

• Denying a conclusion that logically follows from the premises is itself an error.
• If the premises are established, the conclusion must be accepted.
• You can't accept the reasoning but reject the result.
