If the Mc's arguido status is dropped they would be entitled to see what evidence the pj had against them to make them arguidos in the first place. This is was the McCanns are hoping. If the arguido status is extended they will not be allowed to see the evidence against them, however, if they are charged the legal team will be given the prosecution's evidence against their clients to allow them to be in a position to defend them in court against the charges.
