In 1945, the Czechoslovak leaders decided to expatriate Hungarian and German minorities from Czechoslovakia. Cardinal Mindszenty invested all his ethical authority into protests against violations of human rights in both Czechoslovakia and Hungary. In his protests, he attempted to influence representatives of Hungarian and foreign governments and secure their support for the Hungarian issue. Mindszenty argued before various competent forums that the principle of collective guilt was unjust and caused harm to innocent people. He demanded decency and impartial justice for the Czechoslovak Hungarians. Mindszenty pointed out that the church always raised its voice when God's laws, both written and verbal, were broken. He defended the Christians regardless of their origin, nationality, religion or social status. He was most concerned with the fate of Czechoslovak Hungarians. However, he only reached limited results in a few sporadic cases and the expatriation, replacement of citizens and re- Slavonicisation were not terminated in spite of his various proposals.
