This research branch examines the constitutional status of the Mainland Area, the legal significance of the ROC government’s loss of effective control after 1949, and the consequences of long-term de facto administration.
No status theory is predetermined. Constitutional displacement, competing-government, succession, de facto-government, civil-war and occupation-related theories must each be tested against controlling ROC authority, historical evidence, international law and serious contrary arguments.
The branch links directly to FCLR Constitutional Opinion 2026-1 and preserves separate analysis of constitutional title, governmental effectiveness, international recognition, public acts and private-rights continuity.
