The Court of Criminal Appeal has reserved judgment in the appeal by Joe O'Reilly's against his conviction for the murder of his wife.
The 36-year-old is serving a life sentence for murdering his wife Rachel at their home in the Naul in Co Dublin on 4 October 2004.
Joe O'Reilly's legal team had initially put forward 11 grounds for appeal, but the court heard this morning that it would not be pursuing five of those grounds.
The seven grounds put forward today by O'Reilly's lawyers include claims that evidence of emails he had sent should not have been admitted by the trial judge.
O'Reilly's legal team said the emails, sent four months before Rachel's murder, could not fairly be said to show his state of mind when she was killed.
Other submissions included that interviews given by Mr O'Reilly while in garda custody should not have been admitted in evidence because it was clear he had exercised his right to silence.
Patrick Gageby SC said the trial judge was wrong to allow evidence of statements made by Joe O'Reilly to gardaí before his arrest because he was a suspect at the time; the statements had not been made under caution.
He said analysis of CCTV footage of a car matching the description of O'Reilly's car should not have been admitted because a comparison with not carried out with any other vehicle than a Fiat Marea, which O'Reilly drove
O'Reilly's legal team is also challenging evidence in relation to the location of his mobile phone because of a dispute over the licensing of the operator, o2
Replying to the submissions on behalf of the Director of Public Prosecutions, Denis Vaughan Buckley SC said the emails showed the accused absolutely detested his wife and was having an affair.
He said statements made to gardaí before his arrest were perfectly admissible because a person would only be cautioned if a decision had been made to charge them.
