Ala. Code § 37-2-32
Whenever any freight shall be received by any transportation company in this state to be delivered to any consignee within this state, and a portion of the same shall not have been received at the place of destination, it shall be unlawful for the company to demand any part of the charges for freight or transportation due for such portion of the shipment as shall not have arrived at the place of destination. The company shall be required to deliver to consignee such portion of the consignment as shall be required to deliver to consignee such portion of the consignment as shall have been received upon the payment or tender of the freight charges due upon such portion, unless otherwise agreed upon between the consignee and company, but nothing in this article shall be construed as interfering with or depriving a consignor, or other person having authority, of his rights of stoppage in transitu.
