What South Korea had to prove was to have acquired stronger title before the Shimane Prefecture incorporation. That is, Korea is necessary to prove that Korean title had substituted to the title by the effective occupation before it was incorporated by Shimane. However, the effective control by Korea has not been proven at all. The discussion such as not being possible to protest is meaningless if Korea cannot prove this.

Prof. Daijyudo
It is meaningless even if it is assumed that Korea was not able to protest after February, 1905. Because Korea did not do though it was able to control effectively before 1904. They did not manage the sea lions hanting. 

Prof. Serita
Japan made the sea lion hanting a licence system. (SYC.)  Peaceful effective control of Japan continued like this till WW2. 

The judicial precedent that supports these insistences has been presented. And, does the judicial precedent that supports the insistence of a dipsy Korean scholer who cannot even the accurate quotation of the book? Thank you.
