In a statement on Wednesday, Seyed Abbas Mousavi said only Iranian courts have jurisdiction over Iranian nationals.
“Only Iranian courts are judicially competent to look into crimes committed by Iranian nationals,” said Mousavi.
“This case has been examined by the court in accordance with regulations, and Ms. Adelkhah has enjoyed her citizenship rights (during the legal procedure),” the spokesman added.
“The ruling issued is a verdict of first instance and Ms. Adelkhah can appeal the ruling through legal channels,” he added.
Mousavi underlined that the Judiciary of the Islamic Republic of Iran has full independence as stipulated in the Constitution.
He said unilateral interpretations of independent judicial verdicts will be “unconstructive” for relations between the two countries.
“Any threatening and meddlesome tone will further complicate this case, and the Islamic Republic of Iran brooks no disrespect of its sovereign principles, including the independence of the Judiciary,” he added.
