This is different from the system usual in common-law countries, including the United States, in which courts of general jurisdiction from the trial level up to the court of last resort frequently have powers of constitutional review. Following increasing political controversy about some positions of the Constitutional Court of Austria, Kelsen faced increasing pressure from the administration which appointed him to specifically address issues and cases concerning the providence of divorce provisions in state family law. Kelsen was inclined to a liberal interpretation of the divorce provision while the administration which had originally appointed him was responding to public pressure for the predominantly Catholic country to take a more conservative position on the issue of the curtailment of divorce. In this increasingly conservative climate, Kelsen, who was considered sympathetic to the Social Democrats, although not a party member, was removed from the court in 1930. Kelsen and his European years between 1930 and 1940 Sandrine Baume has summarized the confrontation between Kelsen and Schmitt at the very start of the 1930s. This debate was to reignite Kelsen's strong defense of the principle of judicial review against the principle of an authoritarian version of the executive branch of government which Schmitt had envisioned for national socialism in Germany. Kelsen wrote his scathing reply to Schmitt in his 1931 essay, "Who Should Be the Guardian of the Constitution?", in which he defended in plain terms the importance of judicial review over and against the excessive form of executive authoritarian government which Schmitt was promulgating in the early 1930s. As Baume states, "Kelsen defended the legitimacy of the constitutional court by combating the reasons that Schmitt cites for assigning the role of the guardian of the Constitution to the President of the Reich. The dispute between these two lawyers was about which body of the state should be assigned the role of guardian of the German Constitution. Kelsen thought that this mission ought to be conferred on the judiciary, especially the Constitutional Court." Although Kelsen was successful in drafting sections for the Constitution in Austria for a strong court of judicial review, his sympathizers in Germany were less successful. Both Heinrich Triepel in 1924 and Gerhard Anschütz in 1926 were unsuccessful in their explicit drive to instill a strong version of judicial review in Germany's Weimar Constitution. Kelsen accepted a professorship at the University of Cologne in 1930. When the National Socialists came
