The trial of Ibrahim Halawa in Egypt has been adjourned for the 26th time.
Mr Halawa, who is from Dublin, was jailed after being arrested during protests in Cairo in August 2013.
According to Amnesty International, the trial was adjourned today after defence lawyers for some of the 330 defendants asked for more time to challenge video evidence.
The Minister for Foreign Affairs Simon Coveney has welcomed progress in the trial.
"Diplomats from the Irish Embassy were in the court again in Cairo earlier today for the latest hearing in the court case, and there is further encouraging news of progress in the trial," said Mr Coveney.
"The last of the prosecution witnesses were called today, and the judge confirmed that no further prosecution witnesses will be called," he said.
"The presiding judge made clear his determination to move the trial forward quickly and indicated that the defendants and their lawyers, including Ibrahim and his Egyptian legal team, will have their opportunity to put forward their case before the panel of judges in the coming weeks," said Mr Coveney.
Mr Coveney also said that he raised his concerns about Mr Halawa's situation in a telephone call to Egyptian Foreign Minister Sameh Shoukry today.
Colm O'Gorman, of Amnesty International Ireland, said: "Amnesty researchers in Cairo on the night of his arrest confirm that he [Halawa] was sheltering in the Al Fath mosque and could not have committed the violent acts he has been charged with."
Earlier this year the judge referred video evidence to a technical committee for further examination, said Amnesty.
Their report, seen by Amnesty International, suggests that out of the at least 330 defendants currently detained in the case, there is only information relating to two defendants. It does not even mention Ibrahim Halawa, said Amnesty.
Amnesty said that Mr Halawa has spent 1,423 days in prison since his arrest at the age of 17.
The next hearing, scheduled for 16 July, will be spend examining this video evidence, added Amnesty.
