Yugoslav jurist Borislav Blagojevic noted that a "great number of legal institutions and legal relations remain the same in socialist law", further stating that it is "necessary and justified" to put them to use if they are "in conformity with the corresponding interests of the ruling class in the state in question." Importantly, socialist law has retained civil law institutions, methodology and organisation. This can be discerned by the fact that East Germany retained the 1896 German civil code until 1976 while Poland used existing Austrian, French, German and Russian civil codes until its adoption of its own civil code in 1964. Scholar John Quigley wrote that "ocialist law retains the inquisitorial style of trial, law-creation predominantly by legislatures rather than courts, and a significant role for legal scholarship in construing codes."
