If they had been "exonerated", what difference would it make to have the files translated? What a lame excuse!
This is a strange pretext. Has Ferryman a source ?
I think, Montclair, they had more than 20 days because of the Justice holidays.
The investigation arguido delay was over, so they could be assistants of the process (necessarily accompanied by a lawyer). As assistants they could require interventions and there, yes, they needed to have the files studied. But they had the financial support of a Fund that had precisely been created on that purpose.
I'm not sure whether, depending on the developments of the instruction inquiry, there was no risk to be arguidos again. It seems that it was their fear or the fear of their lawyers... Otherwise it doesn't make sense they recruited Mr Halligen instead of having the PJ for free! Though two witnesses in the trial stated that the arguido status wasn't the problem for the McCanns, it certainly was for the TP7 when they mentioned the removing of the arguido status as a requisite before collaborating in the reconstitution.
