Goncalo Amaral had worked on the investigation to find Maddie after she disappeared in May 2007

MADDIE McCann’s parents have lost their new court appeal to silence the ex-cop who claims they covered up their daughter’s death. 

Portuguese Supreme Court judges met this morning to resolve the couple’s fight against a lower court’s decision last April to reverse their 2015 libel win against Goncalo Amaral.

The hearing took place in private in Lisbon this morning. 

The couple could now face a huge legal bill, which had been frozen until the outcome of the final appeal.

It marks a major milestone in Gerry and Kate McCann’s eight-year fight over a book written by Amaral, who led the initial hunt when then-three-year-old Madeleine vanished from their Algarve holiday apartment in May 2007. 

Amaral was ordered to pay Kate and Gerry £430,000 plus interest in damages after losing round one of their libel battle in April 2015 over his hurtful book ‘The Truth of the Lie.’

Appeal judges reversed the initial ruling by a court in Lisbon in April last year, siding with the former police chief and overturning a ban on his book. 

The decision sparked a fresh appeal by the McCanns to the country’s highest law court. 

The McCanns’ Portuguese lawyer Isabel Duarte lodged the couple’s new appeal last May after vowing to fight the U-turn by judges over Amaral’s book.

Criticising the ruling in favour of the ex-police chief, which a friend of the McCanns said had left them “seething,” she said: “This decision was an appreciation of the law and not the facts.

“We can appeal to the Supreme Court which we will do as we have instructions from our clients.”

The judge who ruled in the McCanns’ favour in April 2015 said Amaral’s right to freedom of speech were conditioned by the fact he had been in charge of the investigation into Maddie's disappearance until shortly before the publication of his book.

She concluded he played on his status as a long-serving police officer to present personal opinions and claims about the high-profile case as fact.

The appeal judges said Amaral’s right to express his opinions overruled any duty of confidentiality he had as an ex-police chief heading the Madeleine McCann investigation once the case files were put into the public domain.

Kate, 48, from Rothley, Leics, said Madeleine’s twin siblings Sean and Amelie, now 12, knew about Amaral’s allegations. 

She told the court in July 2014 after applying to make a statement: “I believe that’s what's in Mr Amaral’s book and the documentary is very distressing to adults. To a child it could be very damaging.”

Asked by the judge how she felt after reading the book, she said: “I was devastated. It made me feel quite desperate because of the injustice I felt towards my daughter and our family as a whole.

"It was very painful to read and I felt sad for Madeleine. I also felt anxious and fearful because of the damage I felt it was doing in Portugal.”

She went on to accuse Amaral of “consistently smearing” her and Gerry and claimed they feared the book may have stopped people coming forward with information about their daughter’s whereabouts. 

The full extent of the hunt for the missing Brit was recently revealed with a total of 8.685 across 101 countries and territories.
