n. evidence which the trial judge finds is useful in helping the trier of fact (a jury if there is a jury, otherwise the judge), and which cannot be objected to on the basis that it is irrelevant, immaterial, or violates the rules against hearsay and other objections. Sometimes the evidence which a person tries to introduce has little relevant value (usually called probative value) in determining some fact, or prejudice from the jury's shock at gory details may outweigh that probative value. In criminal cases the courts tend to be more restrictive on letting the jury hear such details for fear they will result in "undue prejudice." Thus, the jury may only hear a sanitized version of the facts in prosecutions involving violence. (See: evidence)
