I know that Schmitt was a Nazi jurist, but did his political theories themselves have a measurable influence on Nazi policy, either through his jurisprudence or through his ideological influence?
It is outside my area of interest, but I remember meeting someone called Dr. Simona Renata who was working on the political legacy of Schmitt a few years ago. If you can find her work on academia.edu or through journals it might help answer your question.
