According to the Swedish news Web site, The Local, Monday's decision ended a high-profile case in which the Swedish Prison and Probation Service tried to prevent a convicted rapist from receiving sexually explicit material in his cell.

The inmate is serving an eight-year jail sentence.

Although prison officials argued pornography posed a security risk at the jail and predicted it would disrupt the treatment of sex offenders, the district administrative appeals court ruled last year restricting an inmate's right to information was potentially more dangerous than the fallout might be from allowing him to look at pornography.

The Prison and Probation Service sought to overturn that decision, but the Supreme Administrative Court upheld the original verdict.
