1. A question that asks what events led to a particular dispute. This type of issue is decided by weighing the credibility of witnesses, the strength of different pieces of evidence, and competing assertions about what events led to a dispute.
2. An issue that turns on locating and interpreting the legal rules of a different jurisdiction - but nevertheless determined to be a question of fact because the judge of this jurisdiction is not qualified or authorized to resolve this as a question of law. In other words, each side is expected to present evidence about whether foreign laws should affect this case and what those laws mean.
See Trier of fact.
