had a near-monopoly on America's phone system, even controlling the equipment attached to its network. In this era, Americans had to lease equipment from "
Ma Bell" or use approved devices. At this time Hush-A-Phone had been around for 20 years without any issues. However, when an AT&T lawyer saw one in a store window, the company decided to sue on the grounds that anything attached to a phone could damage their network.
AT&T, citing the
Communications Act of 1934
The Communications Act of 1934 is a United States federal law signed by President Franklin D. Roosevelt on June 19, 1934 and codified as Chapter 5 of Title 47 of the United States Code, et seq. The Act replaced the Federal Radio Commission with ...

(FCC) ruled in AT&T's favor. It found that the device was a "foreign attachment" subject to AT&T control and that unrestricted use of the device could, in the commission's opinion, result in a general deterioration of the quality of telephone service.
Finding
A federal appeals court dismissed AT&T's claim. The court's decision stated that AT&T's prohibition of the device was not "just, fair, and reasonable," as required under the Communications Act of 1934. Per the judgment, the device "does not physically impair any of the facilities of the telephone companies," nor did it "affect more than the conversation of the user." The court thus exonerated Hush-A-Phone and prohibited further interference by AT&T toward Hush-A-Phone users.
After the ruling, it was still illegal to connect some equipment to the AT&T network. For example, modems could not electronically connect to the phone system. Instead, Americans had to connect their modems mechanically by attaching a phone receiver to an
