Wiley Blount Rutledge, Toomer v. Witsell — Concurrence
“ The requirement that owners of boats fishing in the maritime belt dock at a South Carolina port, unload, pack, and stamp their catch (for tax purposes) , before 'shipping or transporting it to another state,' is not merely a regulation of commerce burdening it in the sense of materially increasing the shipper's costs. Many valid regulations of commerce do this. ”
