Multiphone Latin America v. Millicom International Cellular

U.S. District Court for the Southern District of Florida · Florida · Aug 28, 2025

Misrepresented: Case Law | Response cites at least four existing cases for propositions those opinions do not discuss (e.g., citing Morrison v. Nissan Motor Co., 601 F.2d 139 for an unrelated point); Court identified misapplication of authority. || False Quotes: Case Law | Proposed Sur-Reply and Response attribute quoted language to Cohen v. Cooper (20 So. 3d 453) that does not appear in that opinion; Court identified the misquote. || False Quotes: Case Law | Counsel presented quotes drawn from Westlaw Keynotes as if they were verbatim text from opinions (examples include Rollins and Stewart), a misrepresentation the Court noted. || Fabricated: Case Law | Response cites 'Metropolitan Dade County v. Dyer, 315 So. 2d 442, 444 (Fla. 3d DCA 1975)', which the Court found appears not to exist. || Fabricated: Case Law | Response cites 'QBE Ins. Corp. v. Dome Constr. Corp., 10 So. 3d 676, 678 (Fla. 4th DCA 2009)', another authority the Court determined appears to be nonexistent.
