Ukrainian Court Case Outcome (EDRSR)

A dataset of 14,452 Ukrainian court decisions spanning 2008-2026 from the Unified State Register of Court Decisions (EDRSR), with parsed sections, outcome labels, and temporal epoch annotations. Designed for case outcome prediction and temporal robustness evaluation in legal NLP.

Dataset Description

Each record contains:

  • facts — the factual circumstances section of the decision (model input). Following LEXTREME methodology, only the facts section is provided rather than the full text.
  • dispositive — the operative part of the decision (for label verification).
  • outcome — one of 7 labels (see below).
  • epoch — temporal period: pre_war, hybrid_war, or full_scale.
  • Metadata: court code, judge name, case category, adjudication date, year, jurisdiction type.

Temporal Epochs

The dataset captures three distinct periods in Ukrainian judicial history, enabling cross-temporal generalization research:

Epoch Years Context Records
pre_war 2008, 2010-2013 Peacetime, all courts operational ~3,000
hybrid_war 2014, 2018-2021 Crimea annexation, Donbas conflict (ATO/JFO), partial occupation ~5,000
full_scale 2022-2026 Full-scale invasion, martial law, mass military cases ~7,000

Key distribution shifts across epochs:

  • 2014: Courts in Crimea and parts of Donetsk/Luhansk ceased operating under Ukrainian jurisdiction.
  • 2022+: Surge in military criminal cases (AWOL, desertion, draft evasion); new Criminal Code articles (111-1 collaborationism, 111-2); martial law procedures.
  • Case type mix: Criminal cases shift from property/drug offenses (pre-war) to military offenses (full-scale).

Outcome Labels

Label Description
granted Claim fully granted
guilty Defendant found guilty (criminal/admin)
partial Claim partially granted
closed Proceedings terminated or defendant acquitted
denied Claim denied
plea_deal Plea agreement approved
other Unclassified (mixed/procedural)

Jurisdiction Types

Balanced across all 5 Ukrainian jurisdiction types per epoch:

Code Name Typical outcomes
1 Civil granted / denied / partial
2 Criminal guilty / plea_deal / closed
3 Commercial granted / denied / partial
4 Administrative granted / denied / partial
5 Administrative offenses guilty / closed

Source Data

All decisions sourced from the official EDRSR API. The registry contains 101M+ decisions from 832 courts across Ukraine (2006-present). Personal data is anonymized at the source.

Anonymization tokens: [PERSON], [ADDRESS], [NUMBER], [INFO] replace EDRSR placeholders.

Intended Use

  • Case outcome prediction: Given facts, predict the outcome label.
  • Temporal robustness evaluation: Train on one epoch, evaluate on another to measure distribution shift resilience.
  • Legal NLP benchmarking: Evaluate multilingual models on Ukrainian legal text — a Cyrillic civil-law system underrepresented in benchmarks like LEXTREME.
  • Conflict impact analysis: Study how armed conflict affects judicial outcomes and case distributions.

Limitations

  • Outcome labels are extracted via rule-based regex matching (~5% remain as other).
  • Facts section parsing relies on formatting conventions that vary across courts and time periods.
  • acquitted outcomes are merged into closed due to extreme rarity (~0.1% in Ukrainian courts).
  • Early years (2008-2010) may have lower text quality due to digitization.
  • 2009 is excluded due to insufficient data (52K total records vs 1M+ for other years).
