Rezaian`s lawyer, Leila Ahsan, said Saturday that this hearing would likely be the last, and would be given over to the defense.
It is not clear when the court will issue its verdict. Rezaian faces 10 to 20 years in jail if convicted, but can appeal.
Rezaian, his wife, Yeganeh Salehi, and two photojournalists were detained on July 22, 2014, in Tehran. All were later released except Rezaian, who has Iranian-American nationality.
