Owen J. Roberts, Hansen v. Haff — Opinion of the Court
“ Indeed, the court's opinion implies that, if concubinage were her principal or primary purpose, she ought to be excluded, even though she intended regularly to pursue her work as a domestic. The making of exclusion to depend upon the determination whether the immoral purpose is dominant or subordinate goes far to strike down the statute by making its enforcement difficult and in many cases practically impossible. Congress undoubtedly intended to exclude those who entertain a purpose here to practice prostitution or immorality of that sort. ”
