Louis Brandeis, Swift Company v. United States…
“ The argument is that, as the government made no proof of facts to overcome the denials of the answers, and stipulated both that there need be no findings of fact and that the decree should not constitute or be considered an adjudication of guilt, it thereby abandoned all charges that the defendants had violated the law; and hence the decree was a nullity. The argument ignores the fact that a suit for an injunction deals primarily, not with past violations, but with threatened future ones; and that an injunction may issue to prevent future wrong, although no right has yet been violated. ”
