Motions in Limine Before Derek Chauvin Criminal Trial  

Motions in limine refer to requests to the trial court by prosecutors or defense attorneys to limit the introduction of certain evidence, anticipated questioning by opposing counsel at trial and/or anticipated arguments of opposing counsel at trial. Such motions are often based on Rule 403 of the Minnesota Rules of Evidence, which provides the following: “Although relevant, evidence may be excluded ii its probative value is substantially outweighed by the danger of unfair prejudice, confusion of the issues. or misleading the jury, or by considerations of undue delay, waste of time. or needless presentation of cumulative evidence.” [1]

Both the Prosecution and Derek Chauvin have submitted such motions to the Hennepin County District Court before the commencement of trial on August 8.[2] They are summarized below.
