# 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.
