US Supreme Court weighs dismantling birthright citizenship: a systemic threat to constitutional democracy and global precedents

Indigenous nations within the US have long contested the federal government’s monopoly on citizenship, asserting their own sovereign definitions of belonging rooted in treaties and cultural sovereignty. The 14th Amendment’s citizenship clause was never intended to erase indigenous sovereignty, yet its interpretation has often been used to assimilate Native peoples into a unitary state framework. The current legal challenge risks further eroding indigenous self-determination by subordinating citizenship to federal whims, undermining the trust relationship between tribes and the US government.

The 14th Amendment’s citizenship clause (1868) was a direct response to the Dred Scott decision, which denied Black Americans citizenship, and was designed to ensure that freed slaves and their descendants could not be stripped of rights. This case echoes earlier attempts to redefine citizenship, such as the Naturalization Act of 1790, which limited citizenship to 'free white persons,' and the Chinese Exclusion Act of 1882, which targeted Asian immigrants. The Supreme Court’s role in this case is reminiscent of its complicity in *Plessy v. Ferguson* (1896), where it upheld racial segregation under the guise of 'separate but equal.'

Globally, birthright citizenship (*ius soli*) is the norm in most countries, including France, Germany, and Canada, where it has not led to the demographic or cultural crises feared by nativists in the US. In contrast, countries like Australia and Switzerland have experimented with restrictive citizenship models, often tied to assimilationist policies that marginalize minorities. The US’s unique history of racialized exclusion—from slavery to Jim Crow to modern immigration restrictions—makes its birthright citizenship a fragile but critical bulwark against authoritarian retrenchment.

Empirical research on birthright citizenship shows no correlation between *ius soli* and economic decline or cultural fragmentation; in fact, countries with inclusive citizenship policies tend to have higher social cohesion and economic dynamism. Studies on the 14th Amendment’s impact reveal that it reduced statelessness and provided a legal pathway for marginalized groups to claim rights. The legal arguments against birthright citizenship rely on speculative claims about 'anchor babies' that are not supported by demographic or economic data.

Artists and spiritual leaders have long framed citizenship as a sacred covenant between people and place, not a bureaucratic transaction. Writers like James Baldwin and poets like Audre Lorde have critiqued the violence of exclusionary citizenship, while indigenous activists like Winona LaDuke have reclaimed belonging as a spiritual and ecological relationship. The current legal battle can be seen as a clash between a mechanistic, transactional view of citizenship and a holistic, relational one that honors land, lineage, and collective memory.

If the Supreme Court upholds Trump’s challenge, the US could see a bifurcated citizenship regime where some groups are permanently vulnerable to statelessness, echoing the precarity of undocumented immigrants today. This could trigger a global race to the bottom, with other nations adopting similar policies to curry favor with nationalist movements. Conversely, a ruling affirming birthright citizenship could galvanize transnational movements for inclusive democracy, linking US struggles to those in Europe and Latin America fighting against xenophobic policies.

The voices of Black Americans, whose citizenship was once denied by the Supreme Court, and indigenous peoples, whose sovereignty predates the US Constitution, are entirely absent from this legal debate. Immigrant families, particularly those from Latin America and Asia, face the immediate threat of having their children rendered stateless, yet their perspectives are sidelined in favor of elite legal discourse. The framing also ignores the experiences of children in mixed-status families, who would bear the brunt of such a ruling, perpetuating intergenerational trauma.
