The lawyer for Carson Yeung has asked for the Birmingham owner's case to be thrown out.
Harris says police delays have resulted in an unfair trial. He told the judge that the police started investigating Yeung's financial transactions in 2008 but did not arrest him until June 2011, 10 years after the transactions began.
Harris claims the elapsed time means the lawyers were unable to obtain the relevant documents to help his defense as financial institutions in Hong Kong are only required to hold on to documents for the previous seven years.
