A verdict is expected today in the trial of Dublin man Ibrahim Halawa.
The 21-year-old has been in jail in Egypt for the past four years after being arrested during a political protest.
The verdicts of around 500 other defendants are also expected to be announced.
Colm O'Gorman from Amnesty International Ireland has said the outcomes of mass trials like this are very unpredictable.
"In many mass trails involving hundreds of defendants, we've also seen mass sentences handed down sometimes mass life sentences and indeed mass death sentences," he said.
"It's gong to be a very nervous time for Ibrahim's family, friends and supporters."
Ahead of today's verdict, Ibrahim's sister Nosaybathanks those who have been supporting her brother.
"Hopefully we'll hear good news but I want to thank all of the people that have been supporting us, without their support we wouldn't be at this level," she said.
The Taoiseach confirmed at the weekend that he was scheduled to speak with the Egyptian president today to secure the young man's return to Ireland following the delivery of the verdict. President Abdel-Fattah el-Sissi had earlier stated that he would return
Ibrahim Halawa to Ireland when the trial was completed.
