One of the first actions as a minister was to establish an obligatory program at every Reichs-Rundfunk-Gesellschaft broadcasting company called the "hour of the government". Every day between 6:30 and 7:30 p.m. the companies had to provide 30 minutes of transmission time for representatives of the government. Papen used this opportunity eighteen times in the six months of his term in office while he never spoke at the Weimar German Parliament Gayl was one of the initiators of the Preußenschlag against the Social Democratic government in Prussia in June 1932 but strongly opposed any cooperation with Hitler's Nazi Party.

After Chancellor von Papen had resigned on 17 November, Gayl lost his position with the appointment of Kurt von Schleicher's cabinet on 3 December 1932.
