Full Text of Rule 15-6-44.1
Plain-English Summary
Rule 15-6-44.1 covers the narrow situation where a case turns on the law of another country. A party who plans to raise that kind of issue has to give notice, either in the pleadings or through some other reasonable written notice, rather than springing the question on the court and the other side without warning.
Once the issue is raised, the court has wide latitude in figuring out what the foreign law says. It may consider any relevant material or source, including testimony, whether or not a party submitted it, and whether or not that material would otherwise be admissible under Rule 15-6-43. The court then treats its own determination as a ruling on a question of law, not a finding of fact, meaning the judge decides the question rather than a jury.
