Camden, N.J. — New Jersey's federal district court has postponed judgment in a case that pits the American Trucking Associations (ATA) against a regulation banning interstate truck travel on New Jersey's highway system. Under the regulation, trucks involved in "intrastate access travel" are free to use the state's highway system, but trucks involved in "interstate through travel" are limited to the use of federal highways. The ATA says this violates the Commerce Clause of the U.S. Constitution by favoring in-state economic interests over out-of-state interests. However, the court said it needed more data before issuing a decision on the regulation's descriminatory effects.
