The late Bobby Ryan (left) and Patrick Quirke (right)
Mary Lowry was an "extraordinarily compromised witness" who was bitter towards Patrick Quirke and gave inconsistent and unreliable evidence, an appeal into the farmer's murder conviction heard on Tuesday.
Quirke (51), of Breanshamore, Co Tipperary was convicted last year of the murder of popular DJ and father-of-two Bobby "Mr Moonlight" Ryan (52) at Fawnagowan in Tipperary. Mr Ryan disappeared on June 3, 2011 after he left Ms Lowry's home early in the morning.
His badly decomposed body was discovered in a disused, underground tank on 30 April 2013 on farmland owned by Ms Lowry and leased by Quirke. Quirke had previously had an affair with Ms Lowry and the prosecution argued that he murdered Bobby Ryan so he could rekindle their affair.
Bernard Condon SC for Quirke told the three-judge court that there are 52 grounds of appeal and the hearing will take four days. Outlining his arguments he said his client did not receive a fair trial and was convicted by circumstantial evidence, some of which should not have been heard by the jury.
He said evidence was introduced that wasn't properly proved and he complained that prejudicial comments by gardai during interviews with Quirke should not have been heard by the jury.
Mr Condon said that the circumstantial case relied on blocks of evidence that supported one another and if one of those blocks is removed, "there is a serious question over the overall verdict."
The trial was, counsel said, unsatisfactory, and, "the remedy for an unsatisfactory trial is a satisfactory trial, which I say I am entitled to."
Focusing on Ms Lowry's evidence Mr Condon said that she had presented herself during garda interviews and in her evidence in court as vulnerable and Mr Quirke as controlling.
This was, he said, unsupported by any other evidence and was coming from a woman who Mr Condon described as an "extraordinarily compromised witness".
She was, counsel said, allowed to pick and choose what prejudice she wanted to advance on Mr Quirke, including an accusation that he had assaulted her in 2010.
Counsel added: "That would be bad enough but the guards took ownership of that and ran with it like demons."
There was clear animus and bitterness between Ms Lowry and Mr Quirke, the barrister said, and gardai should therefore have treated her statements with caution.
Mr Condon argued that given what gardai knew from Ms Lowry's inconsistent statements they should have viewed her as an "unusual" and "unreliable" witness and should have video taped her so that the defence would be able to see how her statements came to be made.
He added that gardai should have been more circumspect in accepting what she told them and should not have adopted the position in later interviews with Pat Quirke that Ms Lowry was vulnerable and he was controlling.
The garda approach, he said, had allowed prejudicial evidence to be put before the jury.
In particular he complained of a comment by interviewing gardai that Quirke had "cash on demand and sex on demand" from Mary Lowry.
This comment had generated tabloid headlines, counsel said, because it was "striking". But he said it was unfair and the trial judge should not have allowed it to go to the jury.
Mr Condon said the prosecution also relied on a suggestion that Quirke was financially dependent on Ms Lowry but no forensic accountant was brought in to look at their accounts.
He said the jury was invited to draw inferences from the fact Mr Quirke and Ms Lowry had jointly invested in contracts for difference (CFDs) and that he was leasing her land while claiming a single farm payment. The suggestion was made that this was evidence of Mr Quirke doing something wrong, Mr Condon said, but the prosecution did not call any expert witnesses to give evidence on CFDs or single farm payments.
Mr Condon also complained that "Tittle tattle" regarding "who looked crooked at who" at Lowry family get-togethers was heard by the jury.
During the trial there was a difference of opinion between pathologists. Former Deputy State Pathologist Dr Michael Curtis said the most likely cause of Mr Ryan's injuries was impact with a motor vehicle while former Northern Ireland State Pathologist Professor Jack Crane said there was "no real evidence to support this".
Professor Crane said he had seen similar injuries caused by blunt force trauma with a heavy weapon such as a baseball bat.
Lorcan Staines SC for Mr Quirke told the Court of Appeal that the defence had to call Dr Curtis because the prosecution refused to call him and the trial judge refused to compel the prosecution to call him.
Mr Staines said Michael Bowman SC for the prosecution had taken advantage of being allowed to cross examine Dr Curtis to introduce speculation to suggest that Bobby Ryan was "lured" to a cowshed to be murdered in an area that would be easy to clean up.
Mr Staines said the prosecution would not have been allowed to introduce such speculative evidence if they had called the pathologist and to do so under cross examination was "unfair and wrong".
Entomologist Dr John Manlove told the trial that a fly larva found on Mr Ryan's body had been laid at least 11 days prior to the body being discovered. Engineer Michael Reilly told the trial that the tank that held Mr Ryan's body was airtight when closed and covered with cow droppings left by cattle that were grazing in the area.
The prosecution argued that the presence of the larva showed Quirke had inadvertently let flies into the tank when checking on the body at least 11 days before he staged the discovery of the body.
Mr Staines today said it "beggars belief" that then Deputy State Pathologist Dr Khalid Jaber took only one larva for the entomologist to examine.
There were, Mr Staines said, multiple flies in various stages of development on the body. He also said that the infestation could have been caused by a flood some weeks earlier that caused water to run into the tank from a pipe.
He pointed out that Dr Manlove had accepted that the flood could have caused an opening large enough for flies to get in and argued that the evidence was not admissible because the only reasonable explanation was the one offered by the defence as opposed to the "highly speculative theory" put forward by the prosecution.
The appeal hearing continues on Wednesday in front of Mr Justice George Birmingham (presiding) and Mr Justice Patrick McCarthy and Ms Justice Isobel Kennedy.
