NEGATIVE. This word has several significations. 1. It is used in 
contradistinction to giving assent; thus we say the president has put his 
negative upon such a bill. Vide Veto. 2. It is also used in 
contradistinction to affirmative; as, a negative does not always admit of 
the simple and direct proof of which an affirmative is capable. When a party 
affirms a negative in his pleadings, and without the establishment of which, 
by evidence, he cannot recover or defend himself, the burden of the proof 
lies upon him, and he must prove the negative. 8 Toull. n. 18. Vide 2 Gall. 
Rep. 485; 1 McCord, R. 573; 11 John. R. 513; 19 John. R. 345; 1 Pick. R. 
375; Gilb. Ev. 145; 1 Stark. Ev. 376; Bull. N. P. 298; 15 Vin. Ab. 540; Bac. 
Ab. Pleas, &c. I. 
    202. Although as a general rule the affirmative of every issue must be 
proved, yet this rule ceases to operate the moment the presumption of law is 
thrown into the other scale. When the issue is on the legitimacy of a child, 
therefore, it is incumbent on the party asserting the illegitimacy to prove 
it. 2 Selw. N. P. 709. Vide Affirmative Innocence.
