ELECTRO ENGINEERING PRODUCTS CO., INC., et al., Appellants,
v.
Darrell LEWIS, etc., et al., Appellees.
No. 50894.
Supreme Court of Florida.
October 27, 1977.
Rehearing Denied December 28, 1977.
*863 Mark Hicks, of Blackwell, Walker, Gray, Powers, Flick & Hoehl, Miami, for appellants.
Paul Freedman, of Preddy, Haddad, Kutner, Hardy & Josephs, Miami, and Arnold R. Ginsberg, of Horton, Perse & Ginsberg, Miami, for appellees.
HATCHETT, Justice.
This case is before us to review an interlocutory order of the Dade County Circuit Court which upheld the constitutionality of Florida's Long Arm Statute.[1] We have jurisdiction *864 to treat this interlocutory appeal as a petition for certiorari under Article V, Section 3(b)(3). Burnsed v. Seaboard Coastline Railroad Co., 290 So.2d 13 (Fla. 1974). The denial by the trial court of petitioners' Motion to Dismiss is affirmed because service of process was properly predicated upon a sufficient allegation of jurisdictional facts warranting the exercise of personal jurisdiction over these foreign corporations.
Petitioners, corporations with headquarters in Illinois, allegedly manufactured and distributed the "Electro Rotary Airless Paintgun." Respondent[2] was injured when one of these allegedly defective paint guns suddenly ignited into flames. A complaint was filed seeking recovery for damages, and alleging that the petitioners utilized wholesale houses, mail order outlets, and other outlets for the sale of this paint gun to the general public in the ordinary course of commerce and trade. It was further alleged that this defective product was purchased in 1975 as a result of an advertising campaign which was and is still being conducted in this state, and that this product was distributed by petitioners for use by citizens of this state. Petitioners filed a motion to dismiss, arguing that the complaint alleged insufficient jurisdictional facts to obtain personal jurisdiction over them. If, however, personal jurisdiction was properly obtained pursuant to Florida's Long Arm statute, petitioners assert that this section is unconstitutional for failing to require sufficient "minimum contacts" consistent with petitioners' due process rights under the federal constitution. International Shoe Co. v. Washington, 326 U.S. 310, 66 S.Ct. 154, 90 L.Ed. 95 (1945). Further, petitioners contend that the Florida Legislature exceeded its constitutional authority by directing extra-territorial service of process to be served by officers of foreign states.
To acquire jurisdiction over a non-resident pursuant to this section of Florida's Long Arm statute, the plaintiff must initially allege in the complaint sufficient jurisdictional facts to show that the non-resident manufactured or serviced a product which was used within this state in the ordinary course of commerce and trade, and which injured a person in this state. The burden then shifts to the defendant to make a prima facie showing of the inapplicability of the Long Arm statute. At that time the plaintiff is required to substantiate the jurisdictional allegations in the complaint by affidavits or other competent proof, and not merely reiterate the factual allegations in the complaint. See Dublin Co. v. Peninsular Supply Co., 309 So.2d 207 (Fla.4th DCA 1975), and cases cited therein. However, the allegations of jurisdictional facts in the present complaint remain undisputed, and must be taken as true for the purpose of resolving petitioners' arguments. Here, the facts stated in the complaint show that petitioners manufactured a defective paint gun, and were engaged in the business activity of marketing and distributing this product for use by citizens of this state. These allegations place them within the reach of the Long Arm statute and satisfy the "minimum contacts" required by the federal constitution.
We further determine that service of process was proper pursuant to Section 48.194, Florida Statutes (1975), and determine that there is no conflict between that *865 section and Section 48.011, Florida Statutes (1975). Strict compliance with service of process procedures is required in order to insure that a defendant receives sufficient notice of the legal action brought against him in this state. The fact that our state legislative authority does not extend beyond state borders does not prevent the service of proper notice to non-residents as to suits brought against them here. Section 48.194, Florida Statutes (1975) is constitutional in that it provides a procedure for notifying parties in compliance with the requirements of due process.
The trial court's order denying petitioner's motion to dismiss for lack of personal jurisdiction is affirmed and the case is remanded for further proceedings.
OVERTON, C.J., and ADKINS, BOYD, ENGLAND, SUNDBERG and KARL, JJ., concur.
