Another reminder to take responses to Requests to Admit very seriously is Moy v. Ng, 793 N.E.2d 919 (1st Dist. 2003) (the decision without West's numbering can be found here). In Moy, the First District ruled that the trial court erred in accepting untimely and improper answers to defendant's requests for admissions. Among other problems, the answers were signed and verified by the lawyer, not the party. (Note: seems pretty basic, but I frequently receive unsworn answers, especially when the opposing lawyer is from out of state).
