The Tribunal de Relação de Lisboa (Court of Appeal) justices put much emphases on the archiving report quoting as follows:-
In the archiving dispatch that is signed by two Public Ministry Magistrates, it is written that "From the analysis of the set of depositions that were made it became evident that important details existed which were not fully understood and integrated, which needed to be tested and verified on the location of events itself, thus rendering it possible to establish the apparent failures to meet and the lack of synchronisation, even divergences, in a diligence that is suited for that effect, which was the reconstitution, which was not possible to perform, despite the commitment that was displayed by the Public Ministry and by the PJ, to attain that purpose…"
The justices then discuss at length the dog alerts stating, "The dogs' indications cannot be used as evidence in court, but in multiple cases they provided precious help in terms of collection of evidence for the Scotland Yard and the FBI, with positive results.
... In possession of that new data, and crossing it with the data that had been collected before, the Portuguese authorities - the Public Ministry and the Judiciary Police - tried to perform a reconstitution of the facts, they did and tried everything, but due to the lack of availability of the McCann couple and their friends, who did not show up, said diligence could not be performed and those facts still remain to be clarified.
Concerning that matter, it is written in the final dispatch that "(…) despite the fact that the national authorities took all measures to render their travelling to Portugal possible, due to motives that are unknown, after the many doubts that they raised concerning the need and the opportunity of their travelling were clarified several times, they chose not to show up, which rendered the diligence impossible to perform.
We believe that the main damaged party were the McCann arguidos, who missed the possibility to prove what they have protested since they were made arguidos: their innocence towards the fateful event; the investigation was also hindered, because said facts remain unclear (…)".
They thus put the blame squarely at the feet of the complainants.
