Which global constitution? The illiberal globalism of the US Supreme Court’s Dobbs decision

Fostering global constitutional discourse has long been anathema to the conservative legal movement within the United States. In Dobbs v Jackson Women’s Health Services, which overturned Roe v Wade’s right to an abortion, the court’s conservative justices relied on a globalized analysis. In this article, I identify three potential hypotheses to explain this deviation from conservative orthodoxy. Dobbs’ conservative globalism could be explained by attitudinal preferences, legitimation concerns or the influence of illiberal legal networks. I compare the proceedings of Dobbs against Carson v Makin and Kennedy v Bremerton School District, the other significant Constitutional cases from the court’s 2021–22 term, to deal with religious issues. These two other cases did not feature global citations, despite such citations being able to advance the Justices’ policy preferences or blunt legitimation concerns. Lending credence to the illiberal network hypothesis, Alito’s Dobbs opinion was reliant on a unique amicus briefing by a global network of anti-abortion scholars advocating on behalf of the natural family. Such network campaigns were absent from the proceedings of Carson and Kennedy.
