Under Rule 36 of the Rules of Civil Procedure, failure to respond to admissions automatically deems them admitted in Mississippi. Located here is one of the best briefs I have found dealing with the current caselaw on withdrawing admissions. The case in the brief is currently up on appeal. This is one area that some new law needs to be established in. To me, admissions are a little too much of gamesmanship as opposed an adjudication on the merits.
