Please be aware that in the OP, Note 7 has been amended and Note 9 added.
Note 7 I don't recall what it said previously but the new one states
"Note 7 : The complexity of the filing order, erroneously known as the “AG Report”, is likely related to the difficult task the Public Ministry was facing. And one has to admit that the dispatch is not written as the judges of the STJ remarkably write their rulings. Mr Murat’s arguido status, twice extended, required to put an end to the criminal investigation (the status of arguidos can’t be removed before the end of that investigation phase). Furthermore the acquaintances of the MCs rejected the request of the Prosecutor to go back to PDL in order to be part in a reconstitution of the 3rd of May events, though the Prosecutor clearly warned that it was the last chance for boosting the rather stagnant criminal investigation. These are the significant circumstances involving the writing of the filing order. One has to acknowledge an important point however : the Prosecutors foresaw that their constrained decision, as it couldn’t exonerate the MCs, the crime being undetermined, would reflect the “major damage done to the MCs” by the refusal of the group to collaborate with the PJ."
I still struggle to accept why the McCanns should pay for the non cooperation of the Tapas 7 and Jez Wilkins.
