Carlebach reported how the Upper Silesian Franz Bernheim succeeded to prompt the League of Nations (Bernheim petition [https://archive.today/20120707010834/http://www1.yadvashem.org/odot_pdf/Microsoft%20Word%20-%206006.pdf]) to coerce Germany to abide by the "German-Polish Accord on East Silesia". According to that treaty each contractual party guaranteed in its respective part of Upper Silesia equal civil rights for all the inhabitants. So in September 1933 the Reich's Nazi government suspended in Upper Silesia all anti-Semitic discriminations already imposed and excepted the province from all new such invidiousnesses to be decreed, until the Accord expired in May 1937.
