Lawyers for a young woman whose arrest for wearing a full-face veil sparked riots have argued in court that France's contentious ban on such coverings is unconstitutional and targeted Muslims.
The case relates to Cassandra Belin, 20, who was stopped by police in the gritty town of Trappes, west of Paris, on July 18 for wearing the veil in public.
The incident, in the midst of the Muslim fasting month of Ramadan, led to an altercation and her husband Michael Khiri was arrested and accused of insulting a police officer.
He was later found guilty and got a three-month suspended sentence. The incident sparked two nights of rioting in Trappes, which has a large immigrant population.
Belin's lawyer Philippe Bataille told the court in the western suburb of Versailles on Wednesday that the ban on the veil, which came into force in 2011, impinged on freedom of religion and of movement and went against human dignity.
"How can a woman who is entirely veiled be considered a threat to public order?" Bataille said, adding that the law was discriminatory as "it only applies to Muslims."
France argues that the ban, which was approved by the Constitutional Council in 2010 after three years of intense debate, is necessary for security reasons and to uphold the country's secular traditions.
Critics of the ban say if security is a consideration, then motorcycle helmets should also be outlawed. In theory the ban covers all face coverings but in practice the only arrests have been of women wearing Muslim veils.
Belin's trial for defying the ban and insulting a police officer opened at the end of October but was immediately deferred to Wednesday after her lawyer requested a special procedure under which the Constitutional Council would review a law that has already been passed.
The public prosecutor has asked the court to throw out the request for a review of the ban on the ground that it has already been declared constitutional.
Belin shunned Wednesday's hearing. Her lawyer said she did not want to be wrongly seen as a "symbol of rampant Islamisation."
She has admitted telling the police officers to "shut up" but denied saying, "Allah will crush you."
The police officers claim she also used swear words.
