+
+### Dataset Summary
+
+The dataset is a collection of 4043 *Ementa* (summary) court decisions and their metadata from
+the *Tribunal de Justiça de Alagoas* (TJAL, the State Supreme Court of Alagoas (Brazil). The court decisions are labeled
+according to 7 categories and whether the decisions were unanimous on the part of the judges or not. The dataset
+supports the task of Legal Judgment Prediction.
+
+### Supported Tasks and Leaderboards

+
+### Languages
+
+Brazilian Portuguese
+
+## Dataset Structure
+
+### Data Instances
+
+The file format is jsonl and three data splits are present (train, validation and test) for each configuration.
+
+### Data Fields
+
+The dataset contains the following fields:
+
+- `process_number`: A number assigned to the decision by the court
+- `orgao_julgador`: Judging Body: one of '1ª Câmara Cível', '2ª Câmara Cível', '3ª Câmara Cível', 'Câmara Criminal', '
+  Tribunal Pleno', 'Seção Especializada Cível'
+- `publish_date`: The date, when the decision has been published (14/12/2018 - 03/04/2019). At that time (in 2018-2019),
+  the scraping script was limited and not configurable to get data based on date range. Therefore, only the data from
+  the last months has been scraped.
+- `judge_relator`: Judicial panel
+- `ementa_text`: Summary of the court decision
+- `decision_description`: **Suggested input**. Corresponds to ementa_text - judgment_text - unanimity_text. Basic
+  statistics (number of words): mean: 119, median: 88, min: 12, max: 1400
+- `judgment_text`: The text used for determining the judgment label
+- `judgment_label`: **Primary suggested label**. Labels that can be used to train a model for judgment prediction:
+    - `no`: The appeal was denied
+    - `partial`: For partially favourable decisions
+    - `yes`: For fully favourable decisions
+    - removed labels (present in the original dataset):
+        - `conflito-competencia`: Meta-decision. For example, a decision just to tell that Court A should rule this case
+          and not Court B.
+        - `not-cognized`: The appeal was not accepted to be judged by the court
+        - `prejudicada`: The case could not be judged for any impediment such as the appealer died or gave up on the
+          case for instance.
+- `unanimity_text`: Portuguese text to describe whether the decision was unanimous or not.
+- `unanimity_label`: **Secondary suggested label**. Unified labels to describe whether the decision was unanimous or
+  not (in some cases contains ```not_determined```); they can be used for model training as well  (Lage-Freitas et al.,
+  2019).
+
+### Data Splits
+
+The data has been split randomly into 80% train (3234), 10% validation (404), 10% test (405).
+
+There exist two configurations: judgment and unanimity
+
+#### Judgment
+Label Distribution
+
+| judgment  |    train | validation |    test |
+|:----------|---------:|-----------:|--------:|
+| no        |     1960 |        221 |     234 |
+| partial   |      677 |         96 |      93 |
+| yes       |      597 |         87 |      78 |
+| **total** | **3234** |    **404** | **405** |
+
+#### Unanimity
+
+In this configuration, all cases that have `not_determined` as `unanimity_label` are removed. The splits are not changed other than that.
+
+Label Distribution
+
+| unanimity_label |    train | validation |    test |
+|:----------------|---------:|-----------:|--------:|
+| unanimity       |     1681 |        205 |     200 |
+| not-unanimity   |       34 |          6 |       4 |
+| **total**       | **1715** |    **211** | **204** |
+
+## Dataset Creation
+
+### Curation Rationale
+
+This dataset was created to further the research on developing models for predicting Brazilian court decisions that are
+also able to predict whether the decision will be unanimous.
+
+### Source Data
+
+The data was scraped from *Tribunal de Justiça de Alagoas* (TJAL, the State Supreme Court of Alagoas (Brazil).
+
+#### Initial Data Collection and Normalization
+
+*“We developed a Web scraper for collecting data from Brazilian courts. The scraper first searched for the URL that
+contains the list of court cases […]. Then, the scraper extracted from these HTML files the specific case URLs and
+downloaded their data […]. Next, it extracted the metadata and the contents of legal cases and stored them in a CSV file
+format […].”* (Lage-Freitas et al., 2022)
+
+#### Who are the source language producers?
+
+The source language producer are presumably attorneys, judges, and other legal professionals.
+
+### Annotations
+
+#### Annotation process
+
+The dataset was not annotated.
+
+#### Who are the annotators?
+
+[More Information Needed]
+
+### Personal and Sensitive Information
+
+The court decisions might contain sensitive information about individuals.
+
+## Considerations for Using the Data
+
+### Social Impact of Dataset
+
+[More Information Needed]
+
+### Discussion of Biases
+
+[More Information Needed]
+
+### Other Known Limitations
+
+Note that the information given in this dataset card refer to the dataset version as provided by Joel Niklaus and Veton
+Matoshi. The dataset at hand is intended to be part of a bigger benchmark dataset. Creating a benchmark dataset
+consisting of several other datasets from different sources requires postprocessing. Therefore, the structure of the
+dataset at hand, including the folder structure, may differ considerably from the original dataset. In addition to that,
+differences with regard to dataset statistics as give in the respective papers can be expected. The reader is advised to
+have a look at the conversion script ```convert_to_hf_dataset.py``` in order to retrace the steps for converting the
+original dataset into the present jsonl-format. For further information on the original dataset structure, we refer to
+the bibliographical references and the original Github repositories and/or web pages provided in this dataset card.
+
+## Additional Information
+
+Lage-Freitas, A., Allende-Cid, H., Santana Jr, O., & Oliveira-Lage, L. (2019). Predicting Brazilian court decisions:
+
+- "In Brazil [...] lower court judges decisions might be appealed to Brazilian courts (*Tribiunais de Justiça*) to be
+  reviewed by second instance court judges. In an appellate court, judges decide together upon a case and their
+  decisions are compiled in Agreement reports named *Acóordãos*."
