As the Australian legal system develops, more cases are decided & new interpretations of legal concepts are formed. This just means that both lawyers & judges have to increase their efforts tenfold to simply keep up with the updated precedent. This is when AI legal tools come in handy because they address the issue of having to sift through multiple materials just to confirm whether what youβre reading is still good law.
This article introduces the concept of βprecedent blindnessβ, how it manifests in legal practice, and ways on how to avoid it with the help of AI tools.
What is Precedent Blindness?
βPrecedent blindnessβ is the failure to identify, consider, or properly apply relevant judicial decisions in deciding a legal case or arguing for your clientβs cause. Particularly, precedent blindness can refer to situations where:
- Past judicial interpretations are overlooked,
- Decisions are inconsistent,
- Both judges or lawyers fail to identify similar cases.
In short, precedent blindness is when past judicial decisions are not taken into consideration when making future legal decisions.
Why is Precedent Blindness Wrong?
Precedent blindness is considered harmful to the legal system because it undermines the core principles of a common law legal system such as Australia where courts are expected to decide similar cases consistently. More specific problems that may arise when precedent blindness is not addressed is when:
- Weakening of Stare Decisis
The doctrine of stare decisis is an important legal concept because it ensures that the judiciary decides in such a way that is predictable & unbiased. Without stare decisis, justices would simply be unguided & litigants would remain 100% unsure of their existing rights.
- Increased Litigation Costs
Incorrect or erroneous application of past judicial decisions may cause delays & appeals which give rise to increased litigation costs. Not only do the litigants suffer from this but also the courts since their dockets are clogged in the same way.
- Unfairness to Litigants
Precedent blindness also causes an overall unfairness to the litigants because their case may be decided based on outdated or worse, inexistent decisions.
As such, it is important to avoid precedent blindness as much as possible (if not at all costs).
Preventing Precedent Blindness through AI
With the amount of existing judicial precedent in all the databases across the Australian jurisdictions, it will definitely take days or even weeks for an individual lawyer to sift through all of them. What takes longer is cross-checking them to see if they are still good law to prevent precedent blindness.
How does AI prevent Precedent Blindness
AI legal tools which gives one direct access to AU, NZ, and UK cases and legislation in a single unified database prevent precedent blindness through the following features:
1. Natural Language Processing (NLP)
AI legal tools, instead of searching for exact keywords, tend to:
- interpret legal terminology,
- recognize legal concepts, andΒ
- understand context within judicial reasoning
For example, the terms βnegligenceβ and βdamagesβ are usually found in cases concerning torts however they may be used differently when the court decides on either a civil or criminal case. In this situation, AI can detect whether the court uses language fit for a civil or criminal case.
2. Semantic Search
AI tools also use words based on their definitions and not their exact wording.
For instance, if a lawyer wants to look for past judicial cases on βduty of care in workplace injuriesβ, AI can retrieve cases such as Chopra v NSW Health Service South Western Sydney Local Health District [2024] NSWDC discussing such even if the exact phrase βduty of careβ does not appear.
3. Pattern Recognition
Most importantly, legal AI tools have the ability to analyse legal patterns across thousands of cases by examining similar facts, rulings, and even cited precedents. This comes in handy most especially in avoiding precedent blindness because it can trace for you the history of the legal concept or even judicial decision.
Whatβs more is that legal AI tools can, like CaseChat AI, also tell you if the case you seek to cite is good law or not. For instance, you can simply type in the question βhow did the legal concept of native title come to beβ and it will give you a list of all the cases up to the most updated one answering your question.
Risks in Using AI Legal Tools
While it is a known benefit that AI legal tools can prevent precedent blindness, pure reliance on them for all your verification tasks can pose numerous risks such as the following:
- Hallucinated or False Case Citations
One of the most apparent risks in using legal AI tools is the danger of hallucination or the appearance of false cases just to fill in the AIβs knowledge gaps. To prevent this, lawyers must make it a habit to countercheck with official legal databases or case full texts to ensure that no hallucination occurred.
- Lack of Process Transparency
Sometimes AI legal tools tend to show results that have no clear legal basis or no citations at all. The problem arises when the lawyer is asked to explain how such a conclusion is arrived at.
To avoid this, always make sure to trace the steps the AI took to arrive at its conclusion. You can either verify them yourselves or clarify with the AI how such a conclusion was made/what cases were used.
- Overreliance on AI
Critical legal analysis can get dull over time & especially if not practiced. To avoid this, you have to remember that no AI legal tool will ever replace a lawyerβs critical thinking skills & decision-making.
Conclusion
While AI has the ability to significantly reduce precedent blindness in Australian courts by improving the speed, accuracy, and depth of legal research, a lawyerβs critical thinking skills can not be discounted. To maintain judicial integrity, AI must remain a tool that merely supports human legal reasoning.
As Australian courts continue to modernize, lawyers & the courts must work together to establish ethical safeguards and responsible regulations that ensure AI strengthens, rather than weakens, the integrity of the Australian legal system.
