An inmate at the nation's most secure prison has won a lawsuit challenging the Bureau of Prisons' restrictions on the types of reading materials inmates are allowed to receive by mail.

Thirty-year-old Mark Jordan, who is serving time at Supermax for bank robbery and the June 1999 stabbing death of another inmate, sued the agency in 2003.

He claimed his rights were violated when officials refused to give him some materials that had been mailed to him.

On Thursday, U.S. District Judge Phillip Figa agreed with Jordan that a prison regulation over permissible sources of reading materials was unconstitutional.

Jordan sued after officials refused to deliver to him an Internet printout of a series of essays titled "Justice Denied."

He also was refused mail containing photocopies of magazine articles and newspaper clippings.

Figa has ruled that the regulation did not meet standards set by the U.S. Supreme Court, and ruled that Internet printouts and newspaper and magazine clippings should be treated the same as personal letters and other permissible mail.
