Catherine Nevin has lodged an appeal at the European Court of Human Rights in an effort to overturn her conviction for the murder of her husband.
Nevin has brought the case to the court on the basis that she did not get a fair trial before the Central Criminal Court.
It is understood that she will argue that her case was prejudiced by adverse publicity prior to and during the trial.
Documentation in relation to the case has been lodged already with the European Court and it has accepted that it will hear the matter. However, it is likely to be several months before the case is heard.
Nevin (52) is serving a life sentence following her conviction. Her husband, Tom Nevin, was shot dead at their pub, Jack White's Inn, near Brittas Bay, Co Wicklow, on March 19th, 1996.
In April 2000 Nevin was found guilty of murder and also convicted of soliciting three men to murder her husband on various dates prior to his fatal shooting. She later lost an appeal before the Court of Criminal Appeal against her conviction.
Jack White's Inn was owned jointly by Thomas and Catherine Nevin. Mr Nevin died without leaving a will and the pub was sold by his wife in November 1997 for £620,000.
However, Mr Nevin's estate was later "frozen" by High Court order on the application of members of the late Mr Nevin's family pending the outcome of the criminal proceedings. That order is being challenged by Catherine Nevin in the Supreme Court.
Moves by the Nevin family to get an early hearing of that appeal came before the Supreme Court yesterday but were adjourned for six weeks.
The original proceedings relating to the estate were taken in 1998, when the late Mr Nevin's mother, Mrs Nora Nevin, of Tynagh, Loughrea, Co Galway — who is since deceased — sought a number of declarations from the High Court, including one that Catherine Nevin was not entitled to any share of the premises.
