O R D E R

After consideration of the notice of appeal from an interlocutory order, it 

appears to the Court that: 

(1) The appellant, Hitachi Koki Co., Ltd. (“HKK”),1a Japanese 

corporation with its principal place of business in Toyko, Japan, has petitioned this 

Court, pursuant to Supreme Court Rule 42, to accept an appeal from the Superior 

Court’s opinion dated February 5, 2019, which denied HKK’s motion to dismiss for 

lack of personal jurisdiction.

It appears that the appellant’s name has changed to Koki Holdings Co., Ltd.

(2) Eduardo Diaz Cardona was using a NV83A3 nail gun designed and 

manufactured by HKK when the nail gun allegedly malfunctioned and ejected a nail 

into his eye, causing serious, permanent injuries. Cardona brought an action in 

Superior Court against HKK; Hitachi Koki U.S.A., Ltd. (“HKU”), which is a 

Delaware corporation with its principal place of business in Georgia and a 

whollyowned subsidiary of HKK, created to sell Hitachi power tools in the United 

States market; and Schell Brothers, LLC, which was the general contractor of the 

construction site where Cardona was working at the time of his injury. 

(3) HKK moved to dismiss for lack of personal jurisdiction. After the 

completion of jurisdictional discovery, the Superior Court denied the motion to 

dismiss. The court held that HKK was subject to personal jurisdiction under 

Delaware’s long-arm statute because (i) HKK’s formation of HKU as its exclusive 

U.S. distributor, for the purpose of selling its products in the U.S. market, including 

Delaware, demonstrated HKK’s intent to serve Delaware; (ii) the facts relating to 

sales of Hitachi’s products supported a strong inference that significant numbers of 

the NV83A3 nail gun had been sold in Delaware; and (iii) it was undisputed that 

Cardona was injured by a NV83A3 nail gun used in Delaware.2 The Superior Court 

also held that asserting jurisdiction would comport with the Due Process Clause of

See Cardona v. Hitachi Koki Co., Ltd., 2019 WL 449698, at *4 (Del. Super. Ct. Feb. 5, 2019) 

(applying Boone v. Oy Partek Ab, 724 A.2d 1150 (Del. Super. Ct. 1997), which held that a Finnish 

producer of asbestos was subject to personal jurisdiction in Delaware under the “dual jurisdiction” 
3

the United States Constitution because HKK had sufficient “minimum contacts” 

with Delaware, Cardona’s claims arose out of those contacts, and subjecting HKK 

to jurisdiction in Delaware was not unreasonable.3

(4) The Superior Court denied HKK’s application for certification of an 

interlocutory appeal. The court agreed with HKK that its decision sustained the

controverted jurisdiction of the court 4and arguably involved a question of law 

relating to the construction or application of the long-arm statute.5 But the court held 

that the issue of personal jurisdiction was not a “substantial issue of material 

importance”6 because it does not go to the merits of the case. 7 The court also 

determined that certification would not promote efficient resolution of the case, 

 

theory of personal jurisdiction identified in LaNuova D & B, S.p.A. v. Bowe Co., 513 A.2d 764 

(Del. 1986)).

which has been pending for more than three years, and that the benefits of an 

interlocutory appeal do not outweigh its probable costs.8

(5) We agree that interlocutory review is not warranted in this case. 

Applications for interlocutory review are addressed to the sound discretion of this 

Court.9 In the exercise of its discretion and giving great weight to the trial court’s 

view, this Court has concluded that the application for interlocutory review does not 

meet the strict standards for certification under Supreme Court Rule 42(b). 

Exceptional circumstances that would merit interlocutory review of the decision of 

the Superior Court do not exist in this case, 10 and the potential benefits of 

interlocutory review do not outweigh the inefficiency, disruption, and probable costs 

caused by an interlocutory appeal. 

NOW, THEREFORE, IT IS ORDERED that the interlocutory appeal is 

REFUSED.
