130 U.S. 581 (1889) (U.S. Supreme Court)
Chae Chan Ping v. United States—commonly called the Chinese Exclusion Case—is a cornerstone of U.S.
Whether Congress may, consistent with the Constitution and applicable treaties, bar the reentry of Chinese laborers and invalidate previously issued reentry certificates by enacting the Scott Act of 1888, thereby preventing the holder of such a certificate from returning to the United States.
The political branches possess plenary authority to exclude noncitizens as an incident of national sovereignty and self-preservation, and the judiciary will not second-guess such determinations. For domestic law purposes, treaties and statutes are of equal dignity; where they conflict, the later-in-time rule applies, allowing a subsequent statute to supersede prior treaty obligations. Government-issued permissions to enter or reenter are subject to subsequent legislative revocation and do not create vested rights immune from later congressional action.
Yes. The Supreme Court upheld the Scott Act, holding that Congress had the constitutional authority to exclude Chinese laborers and to invalidate previously issued reentry certificates, even if this action conflicted with earlier treaties with China. Consequently, Chae Chan Ping had no enforceable right to reenter the United States.
Chae Chan Ping is the foundational case for the immigration plenary power doctrine, under which the judiciary affords extraordinary deference to the political branches on admission and exclusion decisions. It also solidifies the last-in-time rule in the immigration context, confirming that later federal statutes control domestically over prior treaties. The case has had enduring influence, paving the way for decisions like Nishimura Ekiu v. United States (exclusion decisions as conclusive), Fong Yue Ting v. United States (extending plenary logic to deportation), and later deference cases including Kleindienst v. Mandel and Trump v. Hawaii. At the same time, the opinion is a cautionary exemplar of how sweeping deference can entrench discriminatory policies. It is routinely criticized for its racialized rhetoric and for enabling exclusion based on national origin. Modern law students should understand both its doctrinal legacy and the subsequent development of constraints—such as recognition of due process protections for persons within the country (e.g., Yamataya v. Fisher) and statutory or constitutional limits on detention (e.g., Zadvydas v. Davis)—that partially temper, but do not eliminate, the core plenary power framework.
