epa07223571 (FILE) - The European Central Bank (ECB) in Frankfurt Main, Germany, 27 April 2017 (reissued 11 December 2018). The Court of Justice of the European Union (CJEU) issued a press release 11 December 2018 saying 'The PSPP (public sector purchase programme) does not exceed the ECB's mandate'. German plaintiffs had brought the European Central Bank's policy called 'quantitative easing' (QE) bond-buying programme before court, saying the bank had exceeded its mandate in 2015 when it started to purchase European government bonds to quell the risk of deflation.
