Deltour was handed a 12 month suspended sentence, while Halet was given a nine month suspended sentence. They also received suspended fines of US$1667 and US$1111 respectively. Edouard Perrin, the journalist who shed light on the affair, was acquitted.
The men's supporters say they acted in the public interest in exposing corporate tax avoidance and that the convictions were an affront to freedom of expression and their fundamental human rights to report a wrongdoing.
"These three men have the support of people from numerous countries across Europe who will all gather to show their support for their actions. The original sentences of Mr. Deltour and Mr. Halet were a total disgrace, and we want this injustice to stop," said Tove Ryding, tax justice coordinator at the European Network on Debt and Development (Eurodad).
"You shouldn't have to go to court for exposing the fact that that multinational corporations are dodging taxes. These men deserve praise, not punishment. The information revealed in the LuxLeaks scandal should never have been secret in the first place, and has been praised by many political leaders," she said.
The scandal brought further investigations into tax arrangement run by Apple, Starbucks and other major companies, as well as calls for companies to be forced to pay taxes on the sale of products and services in the country in which each transaction was actually made.
