The US regulator's 'Click to Cancel' was supposed to take effect next week. But an appeals court has ruled it invalid after cable companies and industry groups sued.

Just days before federal government was to enforce the so-called click-to-cancel rule, an appeals court struck it down, finding the Federal Trade Commission had failed to follow procedural requirements under the law.
