The case of convicted murderer Catherine Nevin, which was due before the Court of Criminal Appeal this morning, will now be heard tomorrow.
It will be the first stage of her attempt to have her conviction declared a miscarriage of justice.
Mrs Nevin is arguing that material which was not given to her lawyers at the time of her trial in 2000 contained information casting doubt on the credibility and motivation of key prosecution witnesses.
Catherine Nevin, 55, is serving a life sentence for the murder of her husband, Tom, at their Co Wicklow pub, Jack White's in March 1996.
She was also convicted of soliciting three men to kill her husband in 1989 and 1990.
In 2003, her appeal against her conviction was dismissed. But she has now brought proceedings under the 1993 Crime Procedure Act to have her case declared a miscarriage of justice.
She argues her conviction should be overturned on the grounds of 'newly discovered facts'.
Her lawyers will be seeking the disclosure of documents, which she claims were withheld from her defence team at her trial on the grounds that they were not relevant.
She will be arguing the documents, including garda security files and documents relating to her husband, would help her to undermine the credibility of the three men who say she asked them to kill her husband and of another State witness.
And she says they would provide an alternative motive for the murder.
