The Swedish website The Pirate Bay has long billed itself as “The world’s most resilient Bit Torrent site” – and more recently suggested it was “The galaxy’s most resilient Bit Torrent site,” but it has come under increased pressure from copyright holders in recent weeks.

Three of file-sharing website The Pirate Bay’s founders -- Fredrik Neij, Peter Sunde, and Carl Lundstrom -- will not be able to argue their case before the Swedish Supreme Court, meaning their previous jail sentences and fines imposed by a lower court of appeals will remain in effect.

According to court documents, a key investor of The Pirate Bay file sharing site appealed to the country's highest court on Monday to overturn his four-month prison sentence and fines to the music and movie industry.

A Swedish appeals court upheld the copyright convictions of three men behind The Pirate Bay, which is a popular file-sharing site that remains in operations.

On Monday, the Pirate Bay's lawyer said the owners of the Swedish file sharing website will seek a retrial after a Dutch court temporarily banned its activities in the Netherlands.
