Date of Decision
2 March 1852
The Court divided interstate and foreign commerce into two categories for which separate national and local rules could apply. Federal rules would apply to business of a "character to require uniformity of treatment" while "local peculiarities of ports" could be appropriately left to the "legislative discretion of the several states."
