The firm's site says: "The Board of Directors of the Argentine Central Bank announced...that the Superintendence of Financial and Exchange Institutions was instructed to apply the legal principle of retroactivity of the 'more favorable criminal law' on the ground of law precedents set forth by the Supreme Court of Justice (in re Cristalux and Docuprint). According to this principle, subsequent rules that are more favourable to the prosecuted persons or entities apply to cases that were before deemed a criminal offence by the Criminal Exchange Regime."

The account also hints that 'rules' - possibly regulatory rules - are also part of this.
