The Basis for the Chen-Soong 10 point consensus is shaky if it's based on the ROC Constitution

In 1895, after China lost the Sino-Japanese war to Japan, China ceded Taiwan to Japan in perpetuity.

The ROC constitution was first drafted when the Republic of China was founded in 1912 after the fall of the Ching dynasty. The China that the Republic of China (ROC) constitution was drafted for clearly did not include the island of Taiwan, since Taiwan was Japanese territory at the time that the Republic of China was founded.

The Republic of China constitution should be considered null and void because it simply was not written for Taiwan nor did the China that it referred to include Taiwan.
