So can I conclude by the silence of both DCI and Brietta that there is no evidence that the PJ, including Paiva, didn't follow leads before marking them ' not relevant'.
Glad we've cleared that one up 
End of mind games for me

Ricardo Paiva received information in Madeleine McCann's case from other policing authorities.
Ricardo Paiva ignored all such information.
Ricardo Paiva marked all such information as irrelevant."Ignored" evidence may lead to re-opening of Madeleine case Algarve ResidentSpecial Report by CHRIS GRAEME at Lisbon Civil Court
Updated: 11-Feb-2010
Lawyers acting on behalf of Kate and Gerry McCann and Gonçalo Amaral admitted in Lisbon on Wednesday (February 10) that evidence ignored by police investigators could pave the way for the Madeleine Case to be reopened.
The lawyers were speaking outside the Lisbon Civil Court, Tribunal Civel de Lisboa, on the last day of an injunction case which the McCanns hope will permanently ban publication of Madeleine – the Secret of the Lie, the book which purports that the three-year-old toddler died in a tragic accident in their holiday apartment in Praia da Luz on May 3, 2007, and that the parents tried to conceal the body.
Isabel Duarte, representing the McCanns, who were in Lisbon at the hearing, said that there was "evidence that could compromise the Polícia Judiciária investigation" in Portimão and pave the way for "the reopening of the Madeleine Case".
The firebrand lawyer, who caused a sensation in the highly-charged court room in her passionate summing up deliberations by using emotive words against the book, the author, its publishers and a television channel, such as vultures, crows and vampires attracted to the "smell of fresh meat" said that she had attempted to show that the PJ had "undervalued successive sightings of a child" which the British police had given credence too.
"What I saw was various relevant pieces of information, photographs, some of them shocking, similar to the girl, places and car number plates," she said, which the McCanns had not been called in to identify, but which could show that a girl like Madeleine could have been in Spain or Italy.
When pressed further, Isabel Duarte said that Inspector Ricardo Paiva, the Chief Investigator in the case after Gonçalo Amaral's removal for allegedly criticising British police, "had been reported as having received sightings of Madeleine" but then later, in court, changed his story.
"What I heard, and this is taped (in court), is that Inspector Paiva said he believed the girl was dead and so, straight off, that means no one is going to investigate a girl that's alive, don't you think?” she said.
Isabel Duarte said that French, Spanish and British investigators had confirmed that the leads "were promising" but that the Portuguese investigators "didn't take them seriously and follow them up".
In a statement outside the court house, Gerry McCann said that the couple would be delighted if the case were reopened.
"We have no problem with that but what we need is real investigation not dismissal," he said as both issued a fresh plea for the Portuguese to come forward with any information about Madeleine.
