'Formal Suspect' - The Portuguese Law
Updated: 13:09, Tuesday May 15, 2007
The Portuguese police now consider Robert Murat to be an Arguido, which translates as a formal suspect.
That means he is considered a suspect but can retain his liberty.
Murat retains libertyMr Murat can be referred to as a defendant but it does not mean he has been accused of a crime.
He is considered important to any future trial whether as an accused or a vital witness.
He is now is part of the judicial process, so he can either be called upon as a man charged with a crime or a man who is a witness vital to a case.
Under "arguido" he now has to obeys the following rules:
:: remain in the country
:: must report to police every 5 days - with proof of residence and ID
:: he cannot change his residence
:: may have the right to an attorney, and if he does he can stay silent
The process leading up to this would have involved an investigation, questioning by the Judicial Police and an order from a judge to search his home
