French Polynesia's Green Party is the latest to express alarm at this week's sacking of Bruno Barrillot, who headed the territory's body concerned with the aftermath of the French nuclear weapons tests.
In an open letter to the French Polynesian president, Gaston Flosse, the party says no objective justification was given to Mr Barrillot for being dumped.
The Greens dismiss suggestions that the one million US dollars paid to Mr Barrillot's organisation was excessive, saying without his work the French Polynesians would never have learnt about France's incessant lies about the tests.
The party says without him no defence secrets would have been lifted and the public would not know that the surveillance of Moruroa is deficient.
It says the cost is insignificant measured against the abuse of public funds by Mr Flosse, for which he has been sentenced and fined.
