Hugo Black,
City of Detroit v. Murray Corporation City of Detroit…
“ For until today the line between property and privilege taxes, if 'drawn by an unsteady hand,' was at least visible. A State could not tax government property, even though the property was in the hands of, and the tax was collectible only from, private persons. However, it now appears that not all property taxes are indeed 'property' taxes for purposes of constitutional immunity, even though so characterized or construed by state authorities. ”
