Dear [Opposing Counsel's Name], I hope this letter finds you well. I am writing to address the recently filed Plaintiff's Amended Designation of Experts in the case of [Case Name]. Firstly, I must express my appreciation for the timely disclosure of the amended expert designations. However, upon reviewing these designations, I find it necessary to raise some concerns on behalf of my client, the Defendant. As you are aware, Puerto Rico is an unincorporated territory of the United States, located in the northeastern Caribbean. This unique status comes with its own legal implications and considerations that must be taken into account during the proceedings of this case. It is crucial to understand that Puerto Rico operates under a legal system that is primarily based on Spanish civil law, with influences from the United States common law. This hybrid legal framework sets Puerto Rico apart from other states in the United States, requiring a thorough understanding of local legal customs and practices. Turning our attention to the Plaintiff's Amended Designation of Experts, it appears that the experts named primarily possess expertise in fields related to the subject of this case. However, it is imperative to consider whether these experts have the necessary understanding of Puerto Rican law and practices providing reliable opinions that align with the jurisdiction in which this case is being tried. In light of the aforementioned considerations, I kindly request that the Plaintiff provide a detailed explanation of the qualifications and experience of each expert listed in the amended designation. Specifically, we seek clarification on any prior involvement of these experts in legal matters within Puerto Rico or their familiarity with the local legal landscape. Such information is crucial for assessing the credibility and reliability of their expert opinions within the context of this case. Furthermore, I would like to propose that both parties engage in a discussion, either through a conference call or in person, to address any concerns and explore the possibility of retaining jointly agreed-upon neutral experts who are well-versed in Puerto Rican law. This collaborative approach would assure that we achieve a fair and impartial evaluation of the issues at hand, consistent with the legal standards and practices of Puerto Rico. I kindly request your prompt response to this letter, as time is of the essence in preparing for the upcoming proceedings. Our willingness to cooperate in this matter demonstrates our commitment to achieving a just resolution and maintaining the integrity of the legal process in Puerto Rico. Thank you for your attention to this matter. I look forward to your response.
