The highest French administrative court has rejected a challenge to the use of the French flag in the campaign for next month's referendum on independence from France.
Several top pro-independence politicians wanted the court to stop the anti-independence side from including the tricolore in its campaign material.
They argued that if approved, the use of the French flag would introduce a bias and risked undermining the outcome of the plebiscite.
By law, French political parties are not allowed to use the tricolore in their material as not to convey the notion that they represent the state.
However in this case, the court dismissed the concern that voters would be confused.
The use of the FLNKS or Kanak flag is also allowed.
In the previous referendum, in 2018, just under 57 percent voted for the status quo.
Should voters again reject independence this year, another referendum can be called by New Caledonia's Congress within the following two years.
