A party who intends to raise an issue concerning the law of a foreign country shall give notice in the pleadings or other reasonable written notice, and at least 30 days prior to the date of trial such party shall furnish all parties copies of any written materials or sources that the party intends to use as proof of the foreign law. If the materials or sources were originally written in a language other than English, the party intending to rely upon them shall furnish all parties both a copy of the foreign language text and an English translation. The court, in determining the law of a foreign nation, may consider any material or source, whether or not submitted by a party or admissible under the rules of evidence, including but not limited to affidavits, testimony, briefs, and treatises. If the court considers sources other than those submitted by a party, it shall give all parties notice and a reasonable opportunity to comment on the sources and to submit further materials for review by the court. The court, and not a jury, shall determine the laws of foreign countries. The court’s determination shall be subject to review as a ruling on a question of law.
