The Supreme Court refused Monday to consider an appeal by satellite television provider EchoStar Communications Corp. of a nationwide injunction barring it from transmitting network television signals.

The Court’s decision is the latest step in a nine-year legal battle between Englewood, Co.-based EchoStar, which operates the DISH satellite network, and the major television broadcast networks and their affiliates. Federal law allows satellite television companies to provide network signals to their customers who are unable to receive local network broadcasts. Such customers are usually rural residents who live beyond local network broadcast areas.
