A temporary injunction can be granted only when there is a showing of (1) the likelihood of irreparable harm; (2) the unavailability of an adequate remedy at law: (3) substantial likelihood of success on the merits. See Naegele Outdoor Advertising Co., Inc. v. City of Jacksonville, 659 So.2d 1046, 1047 (Fla. 1995). A fourth requirement, considerations of the public interest, only applies if a public interest factor is involved in the case. SeeFlorida East Coast Ry. v. Taylor, 47 So. 345 (Fla. 1908).
These elements must also be established by “clear, definite, and unequivocally sufficient factual findings” before the court can enter a temporary injunction. Colucci v. Kar Kare Automotive Gp., Inc., 918 So.2d 431 (Fla. 4th DCA 2006), quoting from Aerospace Welding, Inc. v. Southstream Exhaust & Welding, Inc., 824 So.2d 226, 227 (Fla. 4th DCA 2002).
1. Plaintiff will suffer irreparable harm;
2. Plaintiff has no adequate remedy at law;
3. Plaintiff has a substantial likelihood of success on the merits; and
4. A temporary injunction will serve the public interest
