The majority of the exemptions were issued in 1943, after the deportations were over, and covered as many as 6,000 people, according to Ivan Kamenec's research. However, although these exemptions spared the holder from the requirements of the Jewish Code, such as having to wear a yellow badge, they did not save anyone's life. The exemptions were not honored after the German invasion of Slovakia in August 1944, after which about half of the remaining Jews were deported and murdered. Angry that some exemption holders had joined the partisans, Tiso cancelled many of them.
