Seneca Native Americans in the mail-order cigarette business are awaiting a judge's ruling on whether they will have to comply with a new federal law.

The Senecas say the Prevent All Cigarette Trafficking Act is unconstitutional.

The law prevents businesses from shipping cigarettes through the mail.

It took effect June 29, but the Seneca businesses have not had to comply because of a temporary restraining order that expires at midnight Friday.
