The government accuses Prince Hamza, who was heir to throne until King Abdullah removed him from the position in 2004, of liaising with people linked to foreign parties in a plot to destabilize Jordan and that he had been under investigation for some time.
The decision to dismiss the case was taken on Monday during a closed-door parliamentary session.
In the hemicycle, it is clear that lawmakers heeded a statement by Hamzah about his oath to be loyal to Abdullah II.
Marginalized in 2004 from his right to the throne, the prince denounced he was subjected to house arrest from which he posted on social media an array of criticisms against poor governance and corruption in the country.
Deputy Saleh al-Armouti said the prince will avoid a trial, while another 16 detainees will face justice on charges of attempts to destabilize Jordan.
According to Prime Minister, the case of Prince Hamzah found a solution within the royal family.
