+# Polish SCOTUS-Dec
+
+**Polish SCOTUS-Dec** is a long-document legal text classification dataset
+derived from the publicly available
+[SCOTUS](https://huggingface.co/datasets/pasinit/scotus) dataset.
+
+The dataset contains Polish translations of U.S. Supreme Court opinions.
+The task is a **binary document classification problem** in which the goal
+is to predict the ideological direction associated with the court decision:
+**liberal** or **conservative**.
+
+SCOTUS-Dec is part of the **LongContext** benchmark introduced with
+[Polish ModernBERT](ARXIV_URL).
+
+## Dataset statistics
+
+| Split | Examples |
+|---|---:|
+| Train | 7,413 |
+| Validation | 912 |
+| Test | 931 |
+| **Total** | **9,256** |
+
+SCOTUS-Dec uses the same court opinions and dataset splits as SCOTUS-Dom.
+
+The dataset contains particularly long documents: **74.5% of test examples
+exceed 4,096 tokens** when tokenized with the Polish ModernBERT Base tokenizer.
+
+## Dataset construction
+
+The original English court opinions were translated into Polish using
+**GLM-4.6**. The original SCOTUS train, validation, and test splits and task
+labels were retained.
