A drivers license is issued by a constitutionally created government agency and based on state statute.The difference is that driving a little faster than 65 isn't prohibited by the terms of your drivers license. Having receivers in multiple residences under the same account is expressly prohibited.
The transaction between a customer and a business is a contract between two people or entities and is subject to interpretation by both with disputes settled by mediation, arbitration or civil proceeding. And in all cases both parties are equal before the court.
In other words Dish can prohibit my ass.
Sorry for the harsh language but business disputes are a whole different kettle of fish than violations of law and I tend to resent the imperious tone some take when explaining Dish's view on a matter.
I believe Dish has the same clause in their lease agreement which is why I told the OP that he should only move equipment he owns.The terms over at DIRECTV are similar and they have the additional condition in their equipment lease addendum that demands that you not physically relocate a receiver.
