Dublin Lord Mayor Christy Burke wants the Good Friday ban on alcohol to be lifted in time for Easter 2016.
He believes that stopping the sale of alcohol on Good Friday is "an outdated and draconian law".
"The Vatican doesn't shut down its bars or services for Good Friday, so why should we?" Mr Burke asked.
"My understanding is that hopefully that particular law will be abolished by next year.
"I think it's an old fashioned law. It's draconian."
Mr Burke, who is regularly gifted barrels of Guinness for the Mansion House, believes The Intoxicating Liquor Act actually encourages people to drink more in the run-up to Good Friday.
"I guarantee you, the day before Good Friday the supermarkets will be overloaded with people stocking up as if the city was going to shut down forever," he said.
"And then you have an excess of alcohol consumption."
