The Maritime Piracy Humanitarian Response Programme (MPHRP) called it "crazy" to hand over thousands of euros to nine gunmen who attacked a French cruiseship and yacht in 2008.
The European Court of Human Rights ruled last week that the French government did not put the pirates before a court quickly enough, violating their human rights.
MPHRP programme director Roy Pal said: “This decision would be unbelievable if it wasn’t made by the European Court of Human Rights.
“The claim that this constituted a 'violation of their rights to freedom and security' is an insult to the seafarers and yachtsmen they attacked as surely this is the true violation of the seafarers’ rights to freedom and security.
“These pirates, in my opinion, gave up any of their rights when they set sail to attack innocent seafarers who were simply doing their essential work”.
Paul wants the decision reversed by member states.
He called it an “insult to all in the maritime industry, especially as the judgement was made just before a Vietnamese seafarer was murdered by pirates in an attack on board his vessel.”
The men will be paid up to EUR 9,000 ($11,000).
French authorities were found to have kept them in custody for an extra 48 hours, violating the European Convention on Human Rights.
