Stephen Johnson Field,
Wan Shing v. United States — Opinion of the Court
“ The evidence offered to show that the petitioner was a merchant was weak and unsatisfactory; but the statute itself does away with the necessity for any investigation by the court as to its sufficiency, for it declares that, while the certificate may be controverted by the authorities of the United States, and is to be taken by them only as prima facie evidence, it shall constitute the only evidence permissible on the part of the person producing the same to establish hig right to enter the United States. ”
