The president of New Caledonia's largest pro-independence party Daniel Goa will not be prosecuted for alleged calls for violence and sedition.
Last month, a coalition of anti-independence parties had lodged a formal complaint with the public prosecutor over a speech given by Goa at a party meeting.
Goa had said there was a risk of there being no more provincial elections if the restricted rolls are opened to people who arrived after the signing of the 1998 Noumea Accord.
The anti-independence coalition had also accused Goa of sedition, after he said his side might turn to foreign powers.
After questioning Goa, the prosecutor decided there were insufficient elements to lay charges.
The anti-independence parties want Paris to abolish the restrictions by changing the French constitution and granting voting rights to the estimated 40,000 migrants who have settled since the Accord signing.
In March, the French interior minister Gerald Darmanin said the 2024 provincial elections would not go ahead with the restricted rolls.
Earlier this month, another Caledonian Union politician Gilbert Tyuienon warned that dialogue would end should Goa be taken to court for expressing what the party membership felt.
