McKinnon, 46, of north London, was indicted in 2002 at the U.S. District Court in Virginia for hacking into 97 military and NASA computers between February 2001 and March 2002.

McKinnon's extradition, though approved by the British government in 2006, has been delayed by years of court reviews and legal maneuvering. His case stirred controversy over the fairness of the extradition treaty between the U.S. and U.K., although a legal review completed last October found it was not British defendants.

In 2010, Home Secretary Theresa May of McKinnon's case that had been due to take place in the High Court. Since then, the U.K. government has been conducting an inquiry into McKinnon's medical record. He suffers from Asperger's syndrome, a neurological disorder related to autism characterized by deficiencies in social interaction, as well as depression.

If his extradition is approved the case will proceed to the U.K. High Court, which has scheduled hearings for Nov. 28 and 29, according to Karen Todner, McKinnon's lawyer.

McKinnon has admitted to hacking the computers but asked that his prosecution be conducted in the U.K. The Crown Prosecution Service has declined to prosecute, contending the U.S. wants jurisdiction and that most of the evidence is held by the U.S.
