HUNTINGTON — A federal judge says Marshall University must identify seven students who the music industry claims have illegally downloaded music from the Internet.

U.S. Magistrate Maurice G. Taylor refused on Monday to quash a subpoena obtained by the music industry that seeks the students' names. Taylor gave Marshall 30 days to comply after an amended subpoena is filed.

Marshall had argued that the subpoena was too broad and placed an undue burden on the university's limited resources. In court filings, Marshall said it would cost an estimated $337.50 to investigate each of the seven Internet protocol addresses.

Marshall also contended that identifying the students would violate privacy laws.

The recording industry said companies only wanted identifying information that Marshall already acknowledged having. In a court filing, the industry said it believed Marshall "responded to a virtually identical subpoena less than a year ago, with no cries of undue burden.''

Twelve people were identified as a result of the previous subpoena granted by a federal judge in 2007. The Recording Industry Association of America sued three of those people for copyright infringement. Two of the lawsuits were settled and a default judgment was entered in the third case.

The music industry has sued more than 30,000 people for illegal downloading, many of them college students using university Internet services. Many of the cases have been settled by the defendants agreeing to pay record companies a few thousand dollars apiece.
