South Dublin County Council has passed a motion calling on the Government to immediately apply for a 'presidential decree' on Ibrahim Halawa's behalf.
The Dubliner has been held in an Egyptian prison, without trial, for nearly three years now.
20-year-old Ibrahim, from Firhouse, was arrested at a protest in Cairo in August 2013.
His hearing was postponed again last month - the 14th time the mass trial has been delayed.
The next court date has been set for October 2nd.
A presidential decree would allow him return to Ireland before a final ruling has been made in his case.
The decree - or Law 140 - is used in cases where a deportation or extradition would serve the ‘higher interest’ of the Egyptian state.
Foreign Affairs Minister has already said the Government intends to lend its "full and urgent support" to a further request for release under presidential decree 140.
Sinn Fein Councillor Enda Fanning says the latest motion sends a clear message that South Dublin County Council will continue to support calls for Ibrahim's release.
Cllr Fanning argued: “The Australian Government applied for the Decree pre-sentencing and Australian journalist Peter Greste, a former cell mate of Ibrahim’s, was released and back home with his family before his trial concluded.
“We can only hope that an application for the Presidential Decree on Ibrahim’s behalf will also be successful and allow Ibrahim to return home to his family as soon as possible," he added.
A letter from Mr Halawa claims he has witnessed torture in jail.
