Some of his representative cases include:

  • Batista v. Cooperativa de Vivienda de Jardínes de San Ignacio, et al, 3:10-cv-01238-CVR: Appeared as a Court appointed Pro-Bono Counsel for the Plaintiff, Mrs. Priscilla Batista. The case involved a civil rights claim filed by Mrs. Batista under the Fair Housing Act. Mrs. Batista was a medically indigent and handicapped Senior Person who claimed that she was being evicted from the housing cooperative apartment complex where she lived in retaliation after she filed certain civil rights claims before the federal Housing and Urban Development (“HUD”). The case made it all the way to trial. A Jury reached a verdict in her favor and awarded significant damages to Mrs. Batista.
  • Medicaid and Medicare Advantage Association of Puerto Rico v. Emanuelli-Hernández, 58 F.4th 5, (1st Cir. 2023): Served as Counsel for Co-Plaintiff, MMM Healthcare, Inc..

After a contested litigation that involved numerous intervenors (including the Department of Justice of Puerto Rico and the Office of the Insurance Commissioner), on March 1, 2021, Judge Sylvia Careño Coll, rendered an Omnibus Opinion and Order in favor of the plaintiffs and ruled that Law 90 of 2019 is expressly preempted by the Medicare Modernization Act. After an appeal to the U.S. Court of Appeals for the First Circuit, the Court unanimously affirmed the decision of the USDC-PR.
  • Medicaid and Medicare Advantage Product Association of Puerto Rico, Inc. et al v. Emmanuelli, et al, 3:20-cv-01760-DRD: This case involved a constitutional challenge to the validity of Puerto Rico Laws 138 and 142 of 2020 on federal preemption grounds. As legal representative of Co-Plaintiff MMM Healthcare Inc., he argued that the enactment of these two PR statutes interfered with express preemption provisions contained in the Medicare Modernization Act of 2003, the Federal Employee Healthcare Benefits Act and the Employee Retirement Income Security Act (ERISA). The case was decided in favor of all plaintiffs, and Laws 138 and 142 of 2020 were invalidated in January 2023.

  • Consejo de Salud de Puerto Rico, Inc. v United States of America, 3:18-cv-01045-GAG: As Counsel for the Medicaid and Medicare Advantage Products Association of Puerto Rico (“MMAPA”), he filed an Amicus Curie brief in support of the plaintiff, Consejo de Salud de Puerto Rico. The case involved a legal challenge to a series of federal healthcare statutes that treat the American citizens living in Puerto Rico differently from citizens living on the Mainland states. Such disparate treatment was questioned under the equal protection of the law clause of the fifth amendment of the U.S. Constitution. This case followed a series of similar cases pending before the USDC-PR, the U.S. Court of Appeals for the First Circuit and the Supreme Court of the United States in the leading case of United States v. Vaello-Madero. The case was voluntarily dismissed after the SCOTUS ruling in the case of Vaello-Madero.

  • United States v. Vaello-Madero, Supreme Court of the United States, No. 20-303: This case involved an equal protection claim of a Puerto Rico resident (José Luis Vaello-Madero) that was a recipient of SSI when he lived in the mainland U.S. and was removed from the program after he returned to his homeland, Puerto Rico. The United States Government attempted to collect monies that were paid to him when he returned to the Island. On October 29, 2020, as Co-Counsel for Medicaid and Medicare Advantage Products Association of Puerto Rico, Mr. Prats submitted an Amicus Curie brief before the Supreme Court of the United States in support of Vaello-Madero. The Amicus offered the Supreme Court the legal theory that Puerto Rico’s fiscal autonomy is not a rational basis for the disparate treatment of Puerto Rico and that discrimination against residents of Puerto Rico is subject to a strict scrutiny Constitutional analysis. 

  • MCS Advantage v. Fossas Blanco, CC-2021-0806 : As Counsel for MMAPA, he filed an Amicus Curie before the Supreme Court of Puerto Rico in support of a Motion for Reconsideration. The Amicus brief presented the Court with a legal theory supported by the rulings obtained in the Medicaid and Medicare Advantage Association of Puerto Rico v. Emanuelli-Hernández, 3:19cv-0194-SCC and Medicaid and Medicare Advantage Product Association of Puerto Rico, Inc. et al v. Emanuelli, et al, 3:20-cv-01760-DRD.

  • Iris Cruz Ramos v. Toroverde- Civil No. 21-1078: Represented Toro Verde Adventure Park in a Jury Trial involving a tort liability claim filed by a New York resident. Toro Verde won the case by obtaining a favorable judgment after the parties argued a Rule 50 Motion in open Court.
