It is frequently said that the burden of proof "shifts," that is, that when the affirmative has produced enough evidence to make out a prima facie case, and has shown reason why the plan ought to be adopted, then the burden of proof shifts to the negative and it becomes the duty of the negative to show why the plan should not be adopted. This is not the correct view of the situation, for the affirmative is bound to prove the proposition, in the face of all opposition.
