WASHINGTON (AP) — The Supreme Court has refused to take up a Boston University student's constitutional challenge to a $675,000 penalty for illegally downloading 30 songs and sharing them on the Internet. The high court on Monday refused to hear an appeal from Joel Tenenbaum, of Providence, R.I., who was successfully sued by the Recording Industry Association of America for illegally sharing music on peer-to-peer networks. In 2009, a jury ordered Tenenbaum to pay $675,000, or $22,500 for each song he illegally downloaded and shared.
