Longtime (in internet years) readers will recall my interest in the validity of the 'do-not-call' registry. The 10th Circuit, having vacated the lower court's injunction, has now issued its ruling on the merits, and it upholds the registry. A quick look suggests this case doesn't break new ground. It doesn't try to untangle the confused Supreme Court jurisprudence on content discrimination. Rather, it just says that what the government did here is reasonable (and more likely to be effective than the rule struck down in Hudson Valley, the newsracks case) and that the action is permitted by the statute.
