A more thorough explanation:

A question of fact is an issue that needs to be resolved by a trier of fact, such as a jury or a judge, based on the strength of evidence and credibility of witnesses. It is different from a question of law, which is always resolved by a judge.

For example, in a personal injury case, a question of fact could be whether the defendant's negligence caused the plaintiff's injuries. The jury would need to weigh the evidence presented by both sides and determine whether the defendant's actions were the cause of the plaintiff's injuries.

In some cases, a question of fact may also arise regarding the determination and interpretation of foreign law. In such cases, the party seeking to rely on foreign law must prove it like any other fact that has not been judicially noticed.

For instance, in a contract dispute involving a foreign company, a question of fact could be whether the foreign company's actions were in compliance with the laws of their home country. The jury or judge would need to determine the facts surrounding the foreign law and interpret it accordingly.

Overall, a question of fact is an important aspect of any legal case that requires the trier of fact to weigh the evidence and make a decision based on the facts presented.
