Byron White, Cox v. Louisiana (379 U.S. 559…
“ If the crowd was entitled to obstruct in order to demonstrate as the Court holds, it is nevertheless unnecessary to hold that the demonstration and the obstruction could continue ad infinitum. Here the demonstration was permitted to proceed for the period of time that the demonstrators had requested. When they were asked to disband, Cox twice refused. If he could refuse at this point I think he could refuse at any later time as well. But in my view at some point the authorities were entitled to apply the statute and to clear the streets. ”
