Joseph McKenna, Erickson v. United States — Opinion of the Court
“ The United States is one of the plaintiffs and joined in the suit by way of asserting and seeking to enforce a right in whcih it claims to have a direct and legal interest. Judged by the complaint, the claim made by the United States is not frivolous or wholly without support but is real and substantial. In other words, it calls for consideration and determination. This involves an exercise of jurisdiction, whether the ultimate decision sustains or rejects the claim. Jurisdiction is power to decide the case either way, as the merits may require. ”
