The Mexican Supreme Court has turned down an application to release a French woman from a 60-year jail sentence, in a case that has soured diplomatic relations between the two countries.
Florence Cassez was convicted in 2008 of leading a notorious kidnapping gang.
One of the five Supreme Court judges, Arturo Zaldivar, argued that Cassez’s rights had been infringed denying her a trial.
A key sticking point is the period after her arrest, when instead of being taken to a prosecutor, police made her take part in a staged reconstruction where she was portrayed as the kidnapper. The reconstruction was later aired on TV as a real event.
Cassez has always said her only connection with kidnapping was that her boyfriend at the time was a gang leader.
A majority of the judges did, however, acknowledge violations of her rights and police misconduct which could lead to a retrial.
