Judge's decision on Lauri Love's computers will be heard today
Love, who lives in Newmarket with his parents, wants the return of two laptops, two desktop tower PCs, an SD card, an external hard drive and one of the laptops' hard drives, which were seized from his family home when he was arrested in October 2013.
Today's hearing comes after Love successfully appealed against a 2018 US extradition attempt, which alleged he had hacked a number of government agencies including the FBI and NASA.
Love, who has Asperger syndrome, could have faced a 99 year jail sentence if sent to the US.
The judge will make the ruling later today at at Westminster Magistrates' Court.
