Another highly effective application of CBR is in the legal field. For example, English common law makes extensive use of precedent, or case law. This involves the interpretation of prior case law, statutes and other legal authority. SMART Technology is well attuned to searching legal precedents, producing cases that are substantially similar to the one under consideration. Almost as important, they enable a legal professional to determine how superficially similar cases differ, enabling the argument that precedent does not apply.
