Democracy, Debt, and the Bench: Political Ideology in Sovereign Immunity Cases

Abstract

Following pressure from investors, Congress passed the 1976 Foreign Sovereign Immunities Act (FSIA) to facilitate lawsuits by nonstate commercial actors against sovereign states in US courts. This legislation redefined sovereign debt as a commercial activity, seemingly favoring creditors. Yet case outcomes proved variable. While the FSIA established clear procedural guidelines, judicial discretion remained, raising questions about what factors influence outcomes. How deep is the effect of judges’ partisan leanings? To what extent does a left–right divide exist in this issue area? Although sovereign debt of other countries rarely sparks US political debate, I argue that partisan influence persists in these cases, particularly when defendants are democracies. Republican-nominated judges consistently apply the FSIA’s pro-creditor framework regardless of defendant characteristics, reflecting their party’s historical support for transnational commercial actors and contract enforcement. Democratic-nominated judges, however, exhibit conditional deference: when democracies demonstrate fiscal restraint before defaulting—signaling genuine economic distress—Democratic-nominated judges more readily defer to the sovereign defendant within the FSIA’s constraints. When democracies maintain high government consumption while defaulting, suggesting strategic choice rather than necessity, Democratic-nominated judges enforce more strictly. By contrast, both Democratic- and Republican-nominated judges converge on pro-creditor positions when adjudicating autocratic defaults because the absence of credible fiscal signals eliminates conditions for conditional deference. I test this argument with an original data set of sovereign debt litigation cases brought to the United States from 1977 to 2022.
