ultimate fact

An ultimate fact is a logical conclusion derived from evidence presented during trial and is required for a claim or defense to be successful. An ultimate fact is usually inferred from a number of supporting evidentiary facts and is crucial to the outcome of the case. The fact-finder , such as a jury, must consider the evidentiary details to form the conclusion of the case, that is, the ultimate fact. The ultimate fact, then determines the outcome of the case.

For instance, a jury must accept the ultimate fact that X caused Y's death to convict X of a homicide offense. If the jury is unable to agree on an ultimate fact then the case may be considered a mistrial.
