Anti-Establishment Grading of Bills: Italy and Czech Republic (2017-2022)

The dataset contains data on the holistic grading of anti-establishment salience for all bills introduced to the Italian Parliament (2018-2022) and the Czech Parliament (2017-2021). To assess how political parties contest constitutional identity through legislation, each bill in the dataset was assigned a grade on an ordinal, holistic scale of 0/1/2. This scale captures the degree to which a bill challenges or remains neutral toward the constitutional identity of the respective system. Legislative anti‑establishment behaviour consists of bills that modify a constitutional identity element (ConIDel) (grade 1) or infringe/repeal its material core (grade 2). Bills that either do not challenge the ConIDel or that touch only technicalities receive grade 0. Anchor texts for each anti-e grade and each ConIDel are prepared for each country to ensure replicability, and can be read in the article System-Affirming Tinkerers? Anti-Establishment Parties, Constitutional Identity, and Resilience in Czechia and Italy [under review], and its appendices.本数据集收录了2018-2022年意大利议会、2017-2021年捷克议会提交的全部法案的反建制显著性（anti-establishment salience）整体评分数据。 为评估各政党如何通过立法活动挑战宪法认同（constitutional identity），本数据集中的每一项法案均被赋予0/1/2的定序整体评分。该量表用于衡量法案对对应政体宪法认同的挑战程度或中立程度。立法层面的反建制行为包含两类法案：修改宪法认同要素（ConIDel）的法案（评分1），以及侵犯或废除其实质核心的法案（评分2）。既未挑战宪法认同要素、仅涉及技术细节的法案则被评为0分。 为确保研究可复现，两国均为各反建制评分等级及宪法认同要素（ConIDel）准备了锚定文本，相关内容可参阅论文《肯定体系的修补者？捷克与意大利的反建制政党、宪法认同与韧性》[待刊]及其附录。
