The Waidhofen Resolution was an addendum to The Aryan Clauses adopted by German-national fraternities in the late 1880s.

The Resolution declared jews unqualified to give satisfaction in a duel:

"Every son of a Jewish mother, everyone in whose veins flows Jewish blood, is without honor by birth, devoid of any sublime emotion. He cannot differentiate between what is filth and what is poor. He is a morally unworthy person. Therefore associating with a Jew is dishonorable; one must avoid the company of Jews. One cannot insult a Jew, therefore a Jew cannot demand satisfaction for insults suffered."
