Antoine Deltour was the main whistleblower behind the Luxembourg Leaks case. The former auditor at PricewaterhouseCoopers (PwC) in Luxembourg copied a large number of documents about a system allowing multinational firms to avoid paying taxes. Their disclosure by the ICIJ in 2014 fostered several initiatives for better tax justice. Despite this, Deltour was charged and convicted in Luxembourg. In 2018, after a lengthy judiciary battle, he received whistleblower status as defined by the European Court of Human Rights.
