A Miami federal judge tossed a lawsuit claiming boat and RV owners lost money because of allegedly defective refrigerators.

The case tanked Thursday when U.S. District Judge Robert Scola ruled the plaintiffs have no standing to sue Pompano Beach-based manufacturer Dometic Corp.

The dismissal highlights the challenges of pursuing economic loss claims in product defect cases. Economic loss plaintiffs claim they're damaged not because they experienced a problem with their product, but because they paid more than they would have if they knew it was defective.
