Appellate outcome prediction through expert rationale.
Assessing whether a judgment should be affirmed or reversed is one of the most complex tasks in legal analysis. It requires deep deductive logic, and strict adherence to judicial reasoning. We train specialized Small Language Models (SLMs) to master this exact task, enabling sound and grounded legal logical deduction.
Fine-Tuning on Reasoning Traces
Our Methodology
General purpose frontier models solve complex queries relying on general knowledge acquired during training, potentially enhanced by post training procedures on specific datasets. This processes may not include specific expert knowledge in areas where the how is just as critical as the what. Appellate Law is an example of this.
Our proprietary, graph-based, logic representation enables the creation of high reasoning traces which contain the necessary expertise to teach SLMs the right expert reasoning.
The result is a highly efficient, cost-effective and targeted model that understands the deterministic rules of appellate law better than massive, expensive models.
Beyond Summary: Argumentation Graphs
Sample Analysis of Appellate Record: Ward v. Ruppert Housing Co.
Source Material (Excerpted)
Order, Supreme Court, New York County (Manuel Mendez, J.), entered January 28, 2015, which denied defendant Ruppert Housing Company, Inc.’s motion...
The record presents triable issues of fact as to whether the doormat was an open and obvious condition.
Although plaintiff testified she had previously observed the doormat in the hallway prior to her accident, she also stated that the doormat had never been placed in front of her apartment door.
Furthermore, defendant was aware of the tripping hazards... Plaintiff testified that she complained about the doormat in the hallway, and that defendant failed to act. Thus, the evidence raises issues of fact as to whether defendants breached their common-law duty to maintain the area in a reasonably safe condition.
Motion for summary judgment dismissing the complaint as against it, unanimously affirmed, without costs.

[Extraneous Fact]
General Rule
Open & Obvious Doctrine Applies
Plaintiff previously observed doormat in hallway
Deductive Exception:
Unexpected location overrides generality of known condition.
Mat location was new and immediately in front of door
Tenant complained of hazard; landlord failed to act
Secondary Rule
Breach of Duty to maintain safe premises
Judicial Outcome
