Stanley Matthews, Moran v. City of New Orleans — Opinion of the Court
“ The Louisiana statute declares expressly that if he refuses or neglects to pay the license tax imposed upon him, for using his boats in this way, he shall not be permitted to act under and avail himself of the license granted by the United States, but may be enjoined from so doing by judicial process. The conflict between the two authorities is direct and express. What the one declares may be done without the tax, the other declares shall not be done except upon payment of the tax. In such an opposition, the only question is, which is the superior authority? ”
