LLMs in Interpreting Legal Documents
This chapter explores the application of Large Language Models (LLMs) in the legal domain, highlighting their potential to optimize and augment traditional legal tasks. It covers use cases like interpreting statutes, contracts, and case law, enhancing summarization, negotiation, and information retrieval. Challenges such as algorithmic monoculture, hallucinations, and regulatory compliance (EU's AI Act, US initiatives, China's approaches) are discussed, along with two benchmarks for evaluation.

Interpreting Laws
Information Retrieval (RAG)
Contract Negotiations
Legal Summarisation
LLMs can assist in interpreting legal documents by clarifying vague terms and providing definitions, similar to how judges use dictionaries. They can leverage vast training data for 'ordinary meaning' interpretations. However, risks like hallucinations and regional biases in language exist.

| Feature | LLMs | Traditional Methods |
|---|---|---|
| Speed & Accessibility | High | Low |
| Context Understanding | Good (can 'understand' context) | Limited to explicit definitions |
| Bias Potential | Training data biases, algorithmic monoculture | Human biases in dictionary compilation, surveys |
| Hallucinations | Prone to generating non-existent info | Less prone to outright fabrication of definitions |
| Cost | Free/Subscription | Subscription (dictionaries), time-intensive (surveys) |
Retrieval-Augmented Generation (RAG) integrates precise references from databases into LLM responses, mitigating hallucinations. It involves indexing raw data into vector representations, retrieving relevant chunks based on query similarity, and generating context-expanded answers. This is crucial for legal systems requiring accurate citations.

Addressing Vague Legal Concepts with RAG
Challenge: Legal terms often contain vagueness (e.g., 'dwelling' in China's Criminal Law) requiring precise interpretation based on case precedents.
Solution: A RAG pipeline retrieves relevant past judgments based on the vague concept, filters them for detailed reasoning, and then uses an LLM to interpret and summarize the concept, providing analysis, case examples, and judicial discretion criteria. This ensures interpretations are grounded in legal precedent.
Impact: Improves clarity and consistency in legal interpretations, reduces ambiguity, and supports judges in applying laws based on concrete facts and past rulings.
LLMs can streamline contract negotiations by comparing contracts against standardized templates to identify deviations. This involves Natural Language Inference to classify clause relationships (entailment, contradiction, neutrality) and Evidence Extraction to support these classifications, leading to a clause library of approved terms.

| Clause Type | LLM Utility |
|---|---|
| Limitations of Liability | Identify caps on damages, deviations from template |
| Insurance | Verify specific coverage requirements and discrepancies |
| Indemnity | Analyze compensation terms for losses or damages |
| Representations & Warranties | Assess factual statements and assurances for accuracy |
| Red Flags | Detect unbalanced obligations, confusing provisions |
| System Modifications | Track processes and conditions for amendments |
| Assignment | Verify transfer of ownership or contractual rights |
| Source Code Escrow | Confirm software source code deposit arrangements |
| Audits | Examine rights to verify financial records and compliance |
LLMs can create accessible summaries of complex legal texts, like court opinions, for non-legal readers. This involves both extractive (keywords/phrases) and abstractive (paraphrased) summarization, followed by 'Text Style Transfer' to adjust language to a more public-friendly format, balancing simplification with fidelity to the original meaning.

Enhancing Public Understanding of Court Opinions
Challenge: Legal language ('Legalese') is often inaccessible to the general public, leading to a lack of trust and understanding of judicial decisions. Summarizing complex cases is a time-consuming task for lawyers.
Solution: LLMs perform both extractive and abstractive summarization. They generate 'Facts' (1-2 sentences) and 'Legal Reasoning' (high-level arguments) summaries. 'Text Style Transfer' then modifies the style (e.g., from court opinion to 7th-grade-level essay) to improve readability while defining difficult terms.
Impact: Makes complex judicial texts accessible to a broader audience, improving public understanding and trust. It balances simplification with the need to retain important legal nuances.
