# Admitting Foreign Law Experts: Navigating Rule 44.1 in Court

Posted on March 3, 2025 by Expert Witness Profiler

The case centered on a dispute over property ownership in Cuba. The Plaintiff relied on the testimony of [Avelino Gonzalez](https://expertwitnessprofiler.com/expert-witness/Avelino-Gonzalez/1550559), an expert in Cuban law, to establish their claim. The Defendants, however, challenged the admissibility of Gonzalez’s testimony on multiple grounds.

## **Law And Legal Expert Witness**

[Avelino Gonzalez](https://expertwitnessprofiler.com/expert-witness/Avelino-Gonzalez/1550559) is an attorney with a _Summa Cum Laude_ Bachelor of Law degree from the University of Havana, Cuba, and 35 years of experience in Cuban Law.

## **Discussion by the Court**

### **_Challenges to the Expert’s Testimony_**

The Defendants launched a multi-pronged attack on Gonzalez’s testimony, primarily arguing that:

#### **Improper Use of Expert Opinion**

The Defendants claimed the Plaintiff was improperly using Gonzalez’s opinions to establish disputed facts, arguing Gonzalez lacked personal knowledge of those facts.

#### **Reliance on Inadmissible Hearsay**

They asserted that Gonzalez relied on inadmissible hearsay, particularly a history book and family member accounts, to form his opinions regarding the Plaintiff’s inheritance claim.

#### **Improper Application of Foreign Law**

The Defendants objected to Gonzalez’s ability to opine on the application of Cuban law to the specific facts of the case.

#### **Invasion of the Jury’s Province**

They argued that Gonzalez’s testimony would improperly invade the jury’s role in determining factual matters.

#### **Unreliable Facts and Rule 703 Violation**

They contested the reliability of Gonzalez’s sources, especially the history book, and argued a violation of [Federal Rule of Evidence 703](https://www.law.cornell.edu/rules/fre/rule_703).

### **_The Court’s Observations and Rulings:_**

The Court, however, rejected the Defendants’ arguments and ruled that Gonzalez’s testimony was admissible. Key points from the Court’s observations include:

#### **Rule 44.1 Flexibility**

The Court emphasized the flexibility granted by [Federal Rule of Civil Procedure 44.1](https://www.law.cornell.edu/rules/frcp/rule_44.1), which allows courts to consider “any relevant material or source, including testimony,” when determining foreign law.

#### **Broad Scope of Admissible Evidence**

The Court noted that Rule 44.1 is not constrained by traditional rules of evidence, such as Rule 703 or limitations on hearsay. Thus foreign law experts can use a wide range of documents and sources.

#### **Court’s Role in Determining Foreign Law**

The Court highlighted that determining foreign law is its responsibility, not the jury’s.

#### **Premature Objections**

The Court deemed some objections premature, stating that it would address the parameters of Gonzalez’s testimony and the weight to be afforded to his opinions after reviewing the parties’ motions for summary judgment.

#### **Cross-Examination as a Safeguard**

The Court acknowledged the Defendants’ right to cross-examine Gonzalez to challenge his testimony and raise objections.

## **Held**

The Court denied the Defendants’ motion to exclude the testimony of Avelino Gonzalez.

## **Key Takeaway:**

This case underscores the unique treatment of expert testimony on foreign law in U.S. courts. Rule 44.1 provides significant flexibility, allowing experts to rely on a broad range of materials and sources. While challenges to such testimony are common, courts prioritize their role in determining foreign law and rely on cross-examination to ensure fairness.
