Abstract

This dataset compiles seventeen judicial decisions from Brazil, Chile, and Ecuador (2016–2023) concerning the collective expulsion of migrants in contexts of irregular entry. The cases are coded according to twelve variables. The data allow for the evaluation of judicial dialogue along two dimensions: Visibility of Judicial Dialogue (Form) and Substantive Alignment (Outcome). Additionally, the dataset incorporates qualitative background information from twenty-one interviews conducted between December 2025 and June 2026 with key actors involved in the litigation and adjudication processes across the three jurisdictions. By identifying similarities and differences in the application of regional norms, this dataset supports the findings presented in the article, Vertical Judicial Dialogue and Collective Expulsions in South America: The Cases of Brazil, Chile, and Ecuador.
