 A group of Muslims requested the Constitutional Court to review the law, arguing unstunned ritual slaughter was a key part of the Islamic religion and therefore protected by the freedom of religion.However, the Court unanimously upheld the Act in 2018, stating that 'the Constitution did not allow easily preventable suffering to be inflicted on animals without a justified cause', and that this provision did 'not disproportionally interfere' with religious freedom.Animal welfare is controlled under the provisions of the "Animal Welfare Act 32/2007, of November 7th".
