A hearing to determine if there's sufficient evidence for a trial was adjourned to May 13.
Jamshidi's lawyer, Alberton Richelieu said the prosecution was responsible for the delay.
"The prosecution indicated that they were not ready because they were not in possession of a file," he said, "Although I was ready, and they have been given seven days from now to disclose the file."
Jamshidi, who appeared in court accompanied by his parents, is charged with causing death by gross negligence or recklessness.
Jamshidi has denied the charges, saying that he tried to rescue the boy from drowning after spotting his head bobbling in the water of Bois Shadon beach in the southern town of Vieux Fort.
He remains free on bail.
