The home secretary, Theresa May, has approved the extradition of TVShack founder, Richard O'Dwyer, to the US, where he could face up to five years in prison.
The 23-year-old, who studied at Sheffield Hallam University, set up the site nearly four years ago, offering users links to websites which steamed movies and TV programmes.
He was first convicted by Westminster Magistrates Court in January, with the US government claiming the student made more than $230,000 from the site.
A Home Office spokesperson confirmed the extradition request has now been approved.
"On 9 March after the careful consideration of all relevant materials the home secretary signed an order for Richard O'Dwyer's extradition to the US," the spokesperson said.
Pirate Party leader Loz Kaye wrote on Twitter that he was appalled by the decision.
Deeply shocked at the news that #RichardO'Dwyer's extradition has been approved. This govt should be ashamed.— Loz Kaye (@LozKaye) March 13, 2012
The case echoes that of NASA hacker Gary McKinnon who has fought a ten-year battle over extradition to the US, where he could face up to 70 years in a maximum security jail. A final decision on the case is set for the summer.
McKinnon's mother also expressed her disappointment at the decision to extradite O'Dwyer.
The extradition laws between the UK and the US laws have been widely criticised since former Labour prime minister Tony Blair signed up to them in the wake of the terrorist attacks in September 2001.
