Custuma Antiqua Sive Magna Law and Legal Definition
Custuma antiqua sive magna is an ancient custom were the duties on wool, sheep-skins, or woolfells, and leather, exported were payable by all merchants, both native and strangers. It was by Act of Parliament granted to King Edward the First his heirs and successors for transportation of three things, wools, woolsels, and leather exported out of England. They were payable by every merchant native, as well as stranger, with this difference, that the stranger paid a higher duty than that charged on an Englishman.
