The Supreme Court is expected to deliver its decision tomorrow on an appeal by Seán Quinn Junior against his conviction and imprisonment for contempt of court.
Mr Quinn Jnr is appealing the three-month jail term imposed in July for breaches of court orders not to interfere with the Quinn family's €500m International Property Group (IPG).
He was jailed after the High Court found he failed to take steps to reverse an asset-stripping conspiracy to put funds beyond the reach of IBRC, formerly Anglo Irish Bank.
Lawyers for Mr Quinn argued before the Supreme Court that he was wrongfully convicted of contempt and jailed.
They say the approach taken by the High Court in jailing him indefinitely until the contempt is purged by his father is legally unsound. They also argued there was insufficient evidence to convict him of contempt.
IBRC's lawyers had asked the court to consider what it described as significant new evidence, which they said showed Mr Quinn Jnr had far more control over companies involved in the asset-stripping conspiracy than he previously admitted.
