From facts to cases
Suppose a client tells you: "A Sioux Falls driver hit black ice on a rural highway and was struck by a truck that couldn't stop; the trucking company says our client was driving too fast for conditions." The closest South Dakota decisions on facts like these will tell you more than a keyword search; read them alongside SDCL 20-9-2 on comparative negligence.
LegiMatch ranks real decisions by how closely their facts, issues and statutes match yours - up to 100 per matter - so the most useful cases are at the top. Results link to the courts' text, and the tool doesn't give legal advice.
