noun | ad·mis·sion
: the act or process of admitting admission into evidence
a : a party's acknowledgment that a fact or statement is true
Note: In civil cases admissions are often agreed to and offered in writing to the court before trial as a method of reducing the number of issues to be proven at trial.
b : a party's prior out-of-court statement or action that is inconsistent with his or her position at trial and that tends to establish guilt — compare confession, declaration against interest at declaration
Note: Under the Federal Rules of Evidence an admission is not hearsay. Silence can sometimes be construed as an admission where a person would reasonably be expected to speak up.
