PARIS (AFP) -- France's highest administrative court will decide Friday whether to overturn bans on wearing the full-body burkini swimsuit which have sparked controversy at home and abroad.
The State Council has heard arguments from the Human Rights League and an anti-Islamophobia group which are seeking to reverse a decision by the southern town of Villeneuve-Loubet to ban the Islamic garment.
The ruling, due at 3:00 pm (1300 GMT), is likely to set a precedent for around 30 French towns which have banned the burkini, mostly along the southeast coast.
A court in the Riviera resort of Nice upheld the Villeneuve-Loubet ban this week.
The burkini bans have triggered a fierce debate about the wearing of the full-body swimsuit, women's rights and the French state's strictly-guarded secularism.
President Francois Hollande said Thursday that life in France "supposes that everyone sticks to the rules and that there is neither provocation nor stigmatisation".
The court's ruling will be watched closely abroad as well.
John Dalhuisen, Amnesty International's Europe director, said the French justice system should overturn "a discriminatory ban that is fuelled by and is fuelling prejudice and intolerance".
"French authorities should drop the pretence that these measures do anything to protect the rights of women," he said.
Anger over the issue was further inflamed this week when photographs in the British media showed police surrounding a woman in a headscarf on a beach in Nice as she removed a long-sleeved top.
The office of Nice's mayor denied that the woman had been forced to remove clothing, telling AFP she was showing police the swimsuit she was wearing under her top, over a pair of leggings, when the picture was taken.
The police fined her and she left the beach, the officials added.
Prime Minister Manuel Valls on Thursday condemned any "stigmatisation" of Muslims, but maintained that the burkini was "a political sign of religious proselytising".
"We are not at war with Islam... the French republic is welcoming (to Muslims), we are protecting them against discrimination," he told BFMTV.
But in a sign of the divisions within the Socialist government on the issue, Education Minister Najat Vallaud-Belkacem said the "proliferation" of burkini bans "was not a welcome development".
Vallaud-Belkacem, who is of Moroccan origin, took issue with the wording of the ban in Nice which linked the measure to the jihadist truck attack in the resort last month in which 86 people were killed.
"In my opinion, there is nothing to prove that there is a link between the terrorism of Daesh and what a woman wears on a beach," she said, using another term for Islamic State.
But Valls contradicted his minister's claims, saying the bans were necessary to maintain "public order".
Former president Nicolas Sarkozy who this week launched his bid to regain the presidency, has described the burkini as a "provocation".
The administrative court in Nice ruled Monday that the Villeneuve-Loubet ban was "necessary" to prevent public disorder after the Nice attack and the murder of a Catholic priest by two jihadists in northern France.
The so-called burkini bans never actually mention the word burkini, although they are aimed at the garment which covers the hair but leaves the face visible and stretches down to the ankles.
The vague wording of the prohibitions has caused confusion.
Apart from the incident in the photographs in Nice, a 34-year-old mother of two told AFP on Tuesday she had been fined on the beach in the resort of Cannes wearing leggings, a tunic and a headscarf.
"I was sitting on a beach with my family. I was wearing a classic headscarf. I had no intention of swimming," said the woman, who gave only her first name, Siam.
France firmly separates religion and public life and was the first European country to ban the wearing of the Islamic face veil in public in 2010.
