Opinion

IN THE UNITED STATES DISTRICT COURT FOR THE DISTRICT OF PUERTO RICO

JEANETTE PEREZ-MACEIRA, et al.,

Plaintiffs,

v. CIVIL NO. 23-1445 (CVR)

CUSTOMED, INC., et al.,

Defendants.

OPINION AND ORDER INTRODUCTION The present case is a class action brought by nine (9) representative Plaintiffs individually and on behalf of all others similarly situated, who have lived or participated in activities near three (3) different facilities located in Puerto Rico that sterilize Ethylene Oxide (“EtO”), a known human carcinogen. Defendants are Customed, Inc. (“Customed”) located in Fajardo, Medtronic P.R., Inc. (“Medtronic”) located in Villalba, and Steri-Tech, Inc. (“Steri-Tech”) located in Salinas (collectively, “Defendants”). Plaintiffs brought several claims under different theories of liability, which after some motion practice, the Court reduced to negligence, public and private nuisance. (Docket No. 123). Before the Court is Defendants’ “Motion to Strike Class Allegations Pursuant to Fed.R.Civ.P. 23(d)(1)(D)” (Docket No. 138), and Medtronic’s “Motion to Sever Claims and Drop Defendant Medtronic from this Action Pursuant to Fed.R.Civ.P. 21” (Docket No. 140). Before the Court also is Plaintiffs’ combined Opposition to both motions (Docket No. 154), and Defendants’ Reply to the petition to strike the class allegations (Docket No. 157).

The Court referred both motions to Magistrate Judge Giselle López-Soler (“Magistrate Judge López-Soler”) for a Report and Recommendation (the “R&R”) (Docket Nos. 159 and 160). Defendants timely filed a limited objection to Magistrate Judge López-Soler’s R&R, which Plaintiffs opposed. (Docket Nos. 161 and 162). ANALYSIS The Court may refer dispositive motions to a Magistrate Judge for an R&R. See 28 U.S.C. § 636(b)(1)(B); Fed. R. Civ. P. 72(b). Within fourteen (14) days of receiving a copy of the R&R, “a party may serve and file specific written objections to the proposed findings and recommendations.” Id. Objections must “specifically identify the portions of the proposed findings and recommendations to which objection is made and the basis for the objection.” Local Rule 72(d); see also Fed. R. Civ. P. 72(b)(2). Upon filing of a timely objection, a party is entitled to a de novo determination of the portions of the report or specified proposed findings or recommendations to which specific objections are made. 28 U.S.C. § 636(b)(1)(C); Total Petroleum Puerto Rico Corp. v. Fonseca-Marrero, Civil No. 16-2436 (PAD), 2018 WL 6131777, at *1 (D.P.R. 2018); Ponsa-Rabell v. Santander Securities, LLC, Civil No. 17-2243 (CCC), 2020 WL 4219685, at *1 (D.P.R. 2022); United States v. J.C.D., 861 F.3d 1, 6 (1st Cir. 2017). When performing this review, the Court may “accept, reject, or modify, in whole or in part, the findings or recommendations made by the magistrate judge.” 28 U.S.C. § 636(a)(b)(1). Any portions of the R&R not objected to is reviewed under the “plain error” standard. See Torres Negrón v. United States, 18 F.Supp.3d 89, 91 (D.P.R. 2014) (“[a]bsent objection by the plaintiffs, [a] district court ha[s] a right to assume that [a party] agree[s] to the magistrate’s recommendation.”).

A. The R&R (Docket No. 160). Magistrate Judge López-Soler’s R&R recommended the petition to strike the class allegations be GRANTED IN PART and DENIED IN PART. She found that Plaintiffs’ proposed class definition violated Puerto Rico law, which requires a party to allege and prove an actual physical or emotional injury caused by another’s conduct. The proposed class failed to meet this standard insofar as it included people who have not suffered, and may never suffer, any injury. On this basis, she concluded the class could not be certified as a matter of law and recommended that Plaintiffs be allowed to amend their definition of the proposed class. Magistrate Judge López-Soler then addressed Defendants’ second contention, that even if the class definition was viably amended, individualized questions of injury, causation, and damages would overwhelm any common issues, rendering a class action an inferior method of adjudication under Fed.R.CivP. 23(b)(3). Besides the numerosity, commonality, typicality, and adequacy of representation under Fed.R.CivP. 23(a), a class certification under Fed.R.CivP. 23(b)(3) must also establish that common questions “predominate over any questions affecting only individual members” and the class action must be “superior to other available methods for the fair and efficient adjudication of the controversy.” Fed.R.CivP. 23(b)(3). Magistrate Judge López-Soler concluded that Defendants’ argument was premature because the class did not yet exist, so the Court would be left to speculate about all the certification requirements, particularly predominance and superiority, without the benefit of a concrete class definition. Magistrate Judge López-Soler also noted that Defendants had identified a serious challenge to a class certification, to wit, that toxic-exposure personal injury class actions Page 4 _______________________________
