The empirical literature has consistently shown that judicial ideal points can be estimated in a one‐dimensional space that reflects the traditional conservative‐progressive dichotomy. In this article, we develop an empirical methodology to analyze some features that may characterize bi‐dimensional courts when dissenting opinions are not frequent. We apply the analysis to the particular case of the Consell de Garanties Estatutàries de Catalunya (Catalan Constitutional Court). The results illustrate that judicial preferences on conservative‐progressive grounds are likely to affect the decision outcome of the Court on issues having significant public policy content. Conversely, judicial preferences regarding Spanish‐Catalan sovereignty tend to encroach on judgments concerning public policy, thus affecting the outcome of all judgments of the Court regardless of content type. Furthermore, we find that judicial preferences in the Spanish‐Catalan sovereignty dimension are pervasive enough to shift the outcome of all types of decisions in favor of Catalan institutions. Policy conclusions are derived.

估计二维法院的司法理想点：来自加泰罗尼亚的证据

经验文献一致表明，可以在反映传统保守-渐进二分法的一维空间中估算司法理想点。在本文中，我们开发了一种经验方法，可以分析在不经常出现意见分歧时二维法院可能具有的特征。我们将分析应用于加泰罗尼亚宪法法院（Consell de GarantiesEstatutàriesde Catalunya）的特定案件。结果表明，基于保守-渐进理由的司法偏好可能会影响具有重大公共政策内容的法院的判决结果。相反，关于西班牙-加泰罗尼亚主权的司法偏爱往往会侵犯有关公共政策的判决，因此，无论内容类型如何，都会影响法院所有判决的结果。此外，我们发现，西班牙-加泰罗尼亚主权方面的司法优先权普遍存在，足以使所有类型判决的结果转向加泰罗尼亚机构。得出政策结论。
