This document is a motion in limine filed by Sean Combs’ legal team in his federal criminal case (Case No. 24-cr-542) in the Southern District of New York, seeking to exclude the testimony of Dr. Dawn Hughes, a psychological expert the prosecution intends to call. Dr. Hughes is expected to testify about general behavioral patterns of victims and perpetrators of sexual and domestic abuse, which the defense argues would unfairly bolster the credibility of the government’s witnesses — including alleged victims — without having evaluated any facts specific to this case. The defense asserts that Dr. Hughes’s testimony is not based on a reliable scientific application to the actual circumstances surrounding Combs and instead consists of broad generalizations that risk misleading the jury by presenting “typical” abuse behavior as evidence of guilt.

Combs’ attorneys argue that Hughes’s proposed testimony violates the standards set by Federal Rules of Evidence 702 and 403, which regulate expert witness admissibility. They claim her statements offer no specialized knowledge beyond what jurors already understand — such as abusers exploiting power or victims remaining in abusive relationships — and that she conflates clinical definitions of coercion with legal ones, potentially confusing the jury. The motion asserts that Hughes’s testimony is “advocacy masquerading as expertise” and warns it would improperly bolster the credibility of government witnesses under the guise of psychology. The defense urges the court to block her from testifying, citing that her opinions are methodologically unsound and prejudicial rather than probative.
