Why does an argument end up in the final court decision? Was it deliberated
or questioned during the oral hearings? Was there something in the hearings
that triggered a particular judge to write a dissenting opinion? Despite the
availability of the final judgments of the European Court of Human Rights
(ECHR), none of these legal research questions can currently be answered as the
ECHR's multilingual oral hearings are not transcribed, structured, or
speaker-attributed. We address this fundamental gap by presenting LaCour!, the
first corpus of textual oral arguments of the ECHR, consisting of 154 full
hearings (2.1 million tokens from over 267 hours of video footage) in English,
French, and other court languages, each linked to the corresponding final
judgment documents. In addition to the transcribed and partially manually
corrected text from the video, we provide sentence-level timestamps and
manually annotated role and language labels. We also showcase LaCour! in a set
of preliminary experiments that explore the interplay between questions and
dissenting opinions. Apart from the use cases in legal NLP, we hope that law
students or other interested parties will also use LaCour! as a learning
resource, as it is freely available in various formats at

欧洲人权法院的最终判决由于多语言的口头听证会不被转录、结构化或标注发言人而无法回答法律研究中的问题，通过与相应的最终判决文件相关联的英语、法语和其他法庭语言的 154 个完整听证会（来自 267 小时的视频镜头，共 210 万个标记）的 LaCour！文本口头辩论语料库填补了这一基本空白。
