Autonomy co-founder Mike Lynch is awaiting a Supreme Court ruling in his appeal against extradition to the US to face fraud charges

Mike Lynch has to await a decision from the Supreme Court judges after his appeal against his extradition to the United States.

Lord Justice Lewis and Justice Julian Knowles last week finished hearing the entrepreneur’s objection to the decision of the then home secretary, Priti Patel, who agreed to extradite Dr Lynch to answer charges of criminal fraud in January 2022.

Her decision came after a Westminster Magistrates Court judge ruled that Ms Patel could decide whether to order extradition.

Dr. Lynch has appealed this ruling by District Judge Michael Snow.

Lawyers representing the US government said Judge Snow made “correct” decisions after Dr Lynch lost a multibillion-dollar fraud case in London’s High Court over the sale of the Cambridge software company he co-founded, Autonomy, to Hewlett Packard (HP) in 2011.

Dr. Lynch, who holds a PhD in signal processing – a form of electrical engineering – has been accused of overvaluing his business before it was acquired by the US tech giant.

HP has sued Dr Lynch and Autonomy’s former chief financial officer, Sushovan Hussain, for around $5bn (£3.7bn), after it bought Autonomy for $11.1bn (£8.3bn) more than a decade ago.

The Supreme Court judge who oversaw the trial said HP was “largely successful” in its various claims against the two men – but would likely get “significantly less” than the amount claimed in damages.

Patel wanted to consider Mr Justice Hildyard’s ruling on HP’s claim before making an extradition decision.

Dr. Lynch denied all charges. Lord Justice Lewis and Mr. Julian Knowles have been told that the civil case which Mr. Justice Hildyard has oversaw is far from over.

They heard there was no decision on the amount of damages and said they didn’t know if Dr. Lynch would appeal.

Dr. Lynch has indicated his intention to appeal Judge Hildyard’s ruling.
