The State's appeal against the six-month sentence handed down to sex attacker Anthony Lyons will be heard today.
It will be argued that the penalty imposed on the 52-year-old businessman was too lenient.
The father of four was found guilty by a jury of sexually assaulting a woman on a Dublin street in the early hours of the morning of October 3, 2010.
He admitted the attack but claimed he was overcome with an "irresistible urge" due to the combination of alcohol, cholesterol medicine and cough syrup.
