May 19 (Bloomberg) – The U.S. Supreme Court upheld a federal law aimed at those who advertise or solicit child pornography, rejecting contentions that the measure will chill free-speech rights. The 7-2 ruling is a victory for the Bush administration and restores one of two charges against a Florida man who admitted possession of sexually explicit images of children. The so-called pandering provision, part of a 2003 child- pornography law, lets prosecutors seek a conviction even when sexually explicit images may be computer generated and might not involve actual children. The Bush administration said the provision, though used sparingly, helps dry up the market for child pornography.
