In United States law, the Frye standard, Frye test, or general acceptance test is a judicial test used in some U.S. state courts to determine the admissibility of scientific evidence. It provides that expert opinion based on a scientific technique is admissible only when the technique is generally accepted as reliable in the relevant scientific ...
For evidence to be admissible, it must tend to prove or disprove some fact at issue in the proceeding. [2] However, if the utility of this evidence is outweighed by its tendency to cause the fact finder to disapprove of the party it is introduced against for some unrelated reason, it is not admissible.

Evidence of prior bad acts by the accused will be admissible if the prosecution satisfies the judge on a balance of probabilities that, in the context of the particular case, the probative value of the evidence in relation to a specific issue outweighs its potential prejudice and thereby justifies its ...
An example of inadmissible evidence is that the prosecution generally cannot present character evidence, such as old convictions for unrelated crimes. Courts have ruled that while past criminal behavior may have probative value (because it increases the probability of future criminal behavior) such evidence is too prejudicial to be allowed, as ...
