(a) Delegates shall enter into multistate discussions on behalf of the State of Alabama to consider whether the state should enter into an agreement with one or more states to do the following:
(1) Simplify and modernize tax administration in order to substantially reduce the burden of tax compliance for sellers and for all types of commerce and to provide a means by which sales and use taxes may be collected from remote sellers.
(2) Establish requirements for multistate sellers.
(b) The agreement may provide a mechanism among the member states to establish and maintain a cooperative, simplified system for the application and administration of sales and use taxes from remote sellers under the duly adopted law of each state. No law of this state, nor the application thereof, may be declared invalid as to any person or circumstance on the ground that the provision or application is inconsistent with the agreement. No provision of this division, in whole or in part, invalidates or amends any provision of law in Alabama. Implementation of any condition of any agreement, whether adopted before, at, or after membership of this state in the agreement, must be made by law enacted by the Legislature of this state.
