thanks for polishing my composition!!! The widely-concerned “Amendment (IX) to the Criminal Law” (hereinafter to be referred as “Amendment IX”) shall come into force on Nov. 11th, 2015, which brings about a question that in what sense and to what extent theories of criminal law should play a part in legislation. Research in legislation theory had prevailed for the last 2 decades in the 20th century, as a result, much more interests had been attracted to scholars in study on legal criticism than on effective guidance in juridical practice. Over a decade later, theory of interpretation took over the lead and came to be the mainstream paradigm where scholars had a conviction that “The law is not the object of ridicule”, and to criticize law is a demonstration of the incompetency to interpret it. Under this circumstance, theory of criminal law has been reduced to silence on legislation, and so has its leading and critical role in legislation.
