The punishment: This offender shall be punished with detention for a period not exceeding one year and a fine not exceeding five hundred Egyptian pounds or either penalty. An action shall not be brought versus him except upon a complaint from the concerned party. If, after a ruling is pronounced against him, another action is brought concerning the same crime, his penalty shall then be that of detention for a period not exceeding one year.
