The focal point of the facts concerns a verbal contract of 1967 vintage through which the plaintiff allegedly became an exclusive territorial distributor of bull semen for Carnation Company. It is crucial, given the history of the case, that we examine procedure before substance in our analysis.
When the complaint was filed on 18 April 1979, there were three defendants: Carnation Company, Gary Willier and Warren Manuel. The complaint contains seven counts for relief. The first five counts are designated as against defendant Carnation only: (1) Unfair Trade Practice, (2) Unlawful Price Maintenance, (3) Breach of Contract, (4) Unjust Enrichment, and (5) Fraud. Counts Six and Seven are against the defendants Willier and Manuel only. Count Six is for Conspiracy to Commit Unfair Trade Practices. Count Seven is for Unlawful Interference With Contractual Rights.
Defendants filed a joint Answer on 22 June 1979, which alleges eleven defenses and which was amended to include a twelfth defense on 19 December 1980. Defendants moved for summary judgment on all counts on 4 September 1979, and plaintiff filed cross-motion for partial summary judgment on 23 October 1980.
By order dated 1 January 1981, filed 12 January 1981, the trial judge having held evidentiary hearing, allowed defendants’ motion for summary judgment on Counts Five, Six and Seven, but denied it as to Counts One, Two, Three, and Four. There was no appeal.
On 21 January 1982, the record shows that “Pursuant to Rule 41 of the North Carolina Rules of Civil Procedure, the plaintiff, *383Ben Lloyd, hereby gives notice of voluntary dismissal without prejudice of his claims against Carnation Company.” No mention is made of the defendants Willier or Manuel.
The record contains no formal notice of appeal or appeal entries. However, on page one of the record we find the following language: “Order entered January 1, 1981, dismissing counts 5, 6, and 7 of the Complaint from which Plaintiff excepted in open Court. Upon voluntary dismissal of the remaining Counts of the Complaint, Plaintiff gave Notice of Appeal in open Court to the North Carolina Court of Appeals.” The record was certified by the Clerk of Superior Court on 20 April 1982.
In the plaintiffs grouping of exceptions and assignments of error the record shows but one assignment of error and one exception. The one assignment of error is designated as follows: “The Plaintiff assigns as error the Court’s decision in its Order dated January 1, 1981, to allow the Defendant’s Motion for Summary Judgment as to Counts 5, 6, and 7 of the Complaint; error is assigned on the basis that there are factual issues sufficient in said counts to be decided by a jury . . . .”
Upon this quagmire of conduct, basic procedural questions arise as to the defendant Carnation Company singly and as to defendants Willier and Manuel jointly. The problem will be discussed separately.
I.
Plaintiff’s Appeal as to Carnation Company
[1] The act of plaintiff taking a voluntary dismissal without prejudice by filing a notice of dismissal at any time before the plaintiff rests his case is authorized by Rule 41(a)(1) of the Rules of Civil Procedure. Pursuant to that rule, on 21 January 1982, plaintiff gave “notice of voluntary dismissal without prejudice of his claims against Carnation Company” (emphasis added). Only then does plaintiff “appeal.” By his assignment of error plaintiff now wants us to review the decision of the trial judge entered on 1 January 1981, more than one year prior to the dismissal, when summary judgment was granted on Count Five of the complaint in favor of Carnation Company.
We hold that when plaintiff took a voluntary dismissal without prejudice as to his claims against Carnation Company, he *384destroyed his right to appeal the adverse ruling of 1 January 1981 allowing summary judgment on Count Five of the Complaint. There was nothing left on which to appeal after the voluntary dismissal.
Our research has led us to the case of Pipeliners Local Union No. 798, Tulsa, Okl. v. Ellerd, 503 F. 2d 1193 (10th Cir. 1974), which we choose to use for comparative purposes. The Tenth Circuit was confronted with the procedural situation wherein on 9 February 1972 the trial court had entered a formal order granting all defendants’ motions to dismiss the Complaint for failure to state a claim upon which relief could be granted. The existence of a counterclaim kept the case alive. On 26 September 1973, the plaintiffs took an oral voluntary dismissal in open court of “all actions ‘as to all parties with the exception of the parties to the counterclaim.’ ” Id. at 1199.
The decision of Pipeliners, Id. at 1200, declares: “It is significant, we believe, that appellants’ (i.e., the plaintiffs’) supplemental memorandum on appeal refers to the dismissal order of September 26, 1973, as one ‘voluntarily’ agreed upon by plaintiffs-appellants. The voluntary dismissal constituted a bar to appellants’ attack upon the Order of Dismissal of February 9, 1972.” Of like import is 5 Moore’s Federal Practice ¶ 41.02[6] at 41-43 (2d ed. 1982): “Where plaintiffs’ notice of voluntary dismissal under Rule 41(a)(1) is not disturbed by the trial court or where plaintiff knowingly and willingly agrees to a stipulation of dismissal, he has no standing to appeal.”
In his discussion of the effect of dismissal with and without prejudice, Moore, Id., ¶ 41.05[2] at 41-76, states that “A dismissal without prejudice leaves the situation so far as procedures therein are concerned the same as though the suit had never been brought.” This text is cited with approval in Covey v. C.I.T. Corp., 71 F.R.D. 487, 489-90 (E.D. Okla. 1975). However, as provided in our Rule 41(a)(1) “a new action based on the same claim may be commenced within one year after such dismissal . . . .”
The case of McGoff v. Rapone, 78 F.R.D. 8 (E.D. Pa. 1978), discussed the dismissal procedures under federal practice. The court stated that a voluntary dismissal by stipulation “is not ‘final’ in the sense that, being without prejudice, the plaintiff is free to refile. Similarly, since it does not even require an order
*385. . . then by definition it cannot be an ‘appealable’ order, and in that technical sense it is ‘nonfinal.’ . . . However, ... a Fed. R. Civ. P. 41(a)(1) dismissal is ‘final’ for purposes of a 60(b) motion [relief from judgment], which requires a ‘final judgment, order or proceeding.’ ” Id. at 22.
Athough we have found no North Carolina case directly on point, we believe that the fundamental principles of law concerning standing to appeal in these federal citations are fully applicable to the factual situation before us. The appeal of the plaintiff against Carnation Company is dismissed.
II.
Plaintiff’s Claims Against Defendants Willier and Manuel
[2] The only party-defendants in Counts Six and Seven of the complaint are Willier and Manuel. Plaintiff sought no relief against these defendants within any other Count or claim. Count Six alleges a Conspiracy to Commit Unfair Trade Practices. Count Seven alleges an Unlawful Interference With Contractual Rights. After a December 1980 evidentiary hearing on defendants’ motion for summary judgment as to all claims, the trial judge entered an order dated 1 January 1981, filed 12 January 1981, dismissing Counts Five, Six and Seven in their entirety. To the entry of summary judgment plaintiff excepted in open court but did not appeal.
On 21 January 1982, plaintiff took a voluntary dismissal without prejudice of his claims against the defendant Carnation Company. No mention is made of the defendants Willier and Manuel. Following entry of the voluntary dismissal, plaintiff gave notice of appeal in open court. A full year passed between the granting of the motion for summary judgment and the giving of notice of appeal. There are no appeal entries in the record.
Immediately before the taking of the voluntary dismissal, the case was alive as to the four remaining counts against defendant Carnation Company. By brief and oral arguments the parties tell us that a jury trial of several days’ duration was in progress in January 1982 as to Carnation Company, and that plaintiffs dismissal came before plaintiff rested his case. In open court after *386the voluntary dismissal of Carnation, plaintiff gave his only notice of appeal.
Is the plaintiff “in court” as to the defendants Willier and Manuel? We answer yes and will examine the merits of the granting of summary judgment.
The losing party has no absolute right to appeal immediately from an interlocutory order. As to defendant Carnation Company, the summary judgment against it on Count Five was interlocutory in that the ruling disposed of fewer than all claims, and in that there was no certification by the judge as to substantial need for immediate review on appeal without delay. As to defendants Willier and Manuel, since plaintiff sought no relief against them except as pleaded in Counts Six and Seven, when these two counts were dismissed by summary judgment, the result was that all claims against Willier and Manuel were dismissed.
Plaintiff could have immediately appealed from this interlocutory order, considering that the ruling on summary judgment disposed of all parties and all claims, by virtue of the ruling being final as to all claims of the plaintiff as to each of these two defendants. Plaintiff could have had these two claims certified for appeal by the trial court under Rule 54(b) of the Rules of Civil Procedure. The exception to the court’s ruling of 1 January 1981 kept alive the issue of the correctness of the trial judge’s decision on summary judgment while the plaintiff proceeded with the case against Carnation Company. When during the trial and before resting its case plaintiff took a voluntary dismissal without prejudice as to Carnation Company, and thus terminated the case in the trial division (unless refiled within one year), and when plaintiff gave notice of appeal on 21 January 1982, this provided the plaintiff the first opportunity to appeal without the trial judge’s certification under Rule 54(b). On 21 January 1982 the plaintiff gave notice of appeal within 10 days (ie., the same day) of a final judgment. Prior to 21 January 1982 there was no procedural occasion which made it mandatory for the plaintiff to exercise his otherwise interlocutory right of appeal.
By not exercising his procedural right to immediately appeal on 1 January 1981, plaintiff had to go on to trial as to one defendant only. He ran the risk, if successful on this appeal to have sum*387mary judgment reversed, of having to go to trial twice on similar subject matter claims. Plaintiff lost his right to have all three party-defendants tied together in one lawsuit.
If the voluntary dismissal of 21 January 1982 had included these two defendants, then we would have held against plaintiff on procedural grounds as in Part I of this opinion. Because these two defendants are not included in the voluntary dismissal, and because the plaintiff has minimally preserved for appeal the issue of summary judgment as to Willier and Manuel, we now turn to the merits of plaintiffs appeal.
A motion for summary judgment will be granted if the mov-ant can show “by the use of pleadings, depositions, answers to interrogatories, admissions on file and affidavits that (1) there is no genuine issue as to any material fact, and (2) that [he] is entitled to judgment as a matter of law.” Bell v. Martin, 299 N.C. 715, 718, 264 S.E. 2d 101, 103, rehearing denied, 300 N.C. 380 (1980); G.S. 1A-1, Rule 56(c). The burden is on the moving party to establish, positively and clearly, the absence of a triable issue of fact. See Bank v. Gillespie, 291 N.C. 303, 310, 230 S.E. 2d 375, 379 (1976). The movant can successfully carry this burden when he demonstrates the nonexistence of an essential element of the opponent’s claim, or when he proves the nonexistence of evidence, through discovery, to supply an essential element of the stated claim. Mortgage Co. v. Real Estate, Inc., 39 N.C. App. 1, 4, 249 S.E. 2d 727, 729 (1978), affirmed, 297 N.C. 696, 256 S.E. 2d 688 (1979). Zimmerman v. Hogg & Allen, 286 N.C. 24, 209 S.E. 2d 795, 76 A.L.R. 3d 1004 (1974).
The defendants were the moving parties for summary judgment. The plaintiffs one assignment of error is “that there are factual issues sufficient in said counts [ie., Six and Seven] to be decided by a jury.”
[3] Count Six of the complaint alleges a conspiracy between Willier and Manuel with Carnation to commit unfair trade practices and force plaintiff out of the marketing territories of Virginia, North Carolina, and South Carolina in the purchase and sale of bull semen from Carnation by plaintiff. The unfair acts or practices were alleged to be as defined in G.S. 75-l.Ka), and the entire claim purports to be based on North Carolina law. However, the forecast of all the evidence and discovery *388establishes that if the defendants did the acts and practices, the acts were done entirely within the State of Virginia.
The evidence shows that plaintiff has continued to sell bull semen in the States of North Carolina, South Carolina and also a small territory in Virginia. Plaintiff did not stop his general selling activities in Virginia until he had confirmed that the defendant Manuel was selling in Virginia. The last wrongful act upon which plaintiff relies for this claim took place in Virginia: the selling by Carnation of semen to Manuel in Virginia only. It is not disputed that all of plaintiffs meetings with Manuel took place in Virginia. All discussions between Manuel and Willier and plaintiff took place in Virginia. Of the three marketing states, Virginia is undisputedly the State covered by plaintiffs alleged contract with Carnation and in which Carnation allegedly has sold semen to a would-be competitor of plaintiff.
Under the principles of conflict of laws, the North Carolina trial and appellate courts must apply the substantive law of Virginia to Count Six. See Shaw v. Lee, 258 N.C. 609, 129 S.E. 2d 288 (1963); Charnock v. Taylor, 223 N.C. 360, 26 S.E. 2d 911, 148 A.L.R. 1126 (1943); and Chewning v. Chewning, 20 N.C. App. 283, 201 S.E. 2d 353 (1973). It appears to us that Virginia had not adopted an unfair or deceptive trade practices act comparable to our G.S. 75-1, et seq., cf. 4 Virginia Code § 18.2-499 and 18.2-500 (1982). Because Virginia has not adopted a similar statute, the plaintiffs allegations of wrongful acts and injuries committed in the State of Virginia which allegedly are based on the North Carolina statutes are of no avail. The North Carolina statute cannot be constitutionally applied in Virginia. See Home Ins. Co. v. Dick, 281 U.S. 397, 74 L.Ed. 926, 50 S.Ct. 338, 74 A.L.R. 701 (1930).
We hold that the trial court was correct in dismissing Count Six and in granting summary judgment on this count for defendants Willier and Manuel.
[4] As to Count Seven, plaintiff alleges that defendants Willier and Manuel unlawfully interfered with plaintiffs contract rights with defendant Carnation Company and induced Carnation to remove plaintiff from his marketing territory. For the same reasons as discussed in our consideration of Count Six, we hold that the law of the State of Virginia applies to Count Seven. We are unaware of any statute or case law of Virginia which *389recognizes this purported cause of action. Thus, summary judgment on Count Seven was properly granted by the trial judge.
Even if it were argued that North Carolina law should be applied, our law does not rescue the plaintiff. Upon a further review of the facts, all of the evidence shows that it was Carnation who first contacted Manuel. Manuel in turn unsuccessfully negotiated with plaintiff and went his own way in Virginia until once again Carnation contacted him. Manuel pursued his own personal business interest with the plaintiff in a contact he did not originate. The forecast of the evidence does not establish any inducement by Manuel of Carnation to do anything against the plaintiff.
The complaint alleges that Willier and Manuel had once been employees of American Breeders Service and that Willier and Manuel were close personal friends. Willier introduced Manuel to plaintiff. According to the complaint, in 1977 it was “stated by Willier in the presence of the Plaintiff and Manuel that any new marketing arrangements for the State of Virginia would have to be done under the authority and with the consent of the Plaintiff.” The defendant Carnation Company on 19 January 1978 terminated “all distribution arrangements with [plaintiff] because of ‘unsatisfactory sales.’ ”
The undisputed facts show that any oral or written agreements which plaintiff had with Carnation were terminated in writing by Carnation on 19 January 1978. The forecast of the evidence shows that this decision originated with Carnation and not with the defendants Willier or Manuel. In addition, Carnation continued to sell to plaintiff in spite of the termination of all contracts. Willier, at most, was attempting to be helpful to both Manuel and plaintiff, to help each of them in their own prospective business adventures, which never worked out and which died aborning.
Regardless of whether it is the law of Virginia or North Carolina that should be applied, plaintiff loses on yet another defect. Count Seven of the complaint is fatally defective for failure to allege that plaintiff’s contract with Carnation would have been continued but for the acts and practices of Manuel and Willier; and plaintiff failed to allege any facts to support his conclusion that Manuel and Willier acted maliciously. Even assuming *390these two allegations were in the complaint, there is in the record no forecast of evidence to support an inference that Carnation would have renewed the contract with plaintiff after his record of poor sales or any evidence that any defendant acted maliciously.
We hold that the trial judge correctly allowed summary judgment on Count Seven.
We hold that the entry of summary judgment in favor of defendants Willier and Manuel was proper; and that the voluntary dismissal without prejudice as to defendant Carnation Company precludes us from any consideration of plaintiffs subsequent appeal of the prior granting of summary judgment in favor of Carnation Company.
Assuming arguendo that the plaintiff has preserved his right to appeal after the taking of the voluntary dismissal as to Carnation Company, and assuming it is proper to reach the merits as to Count Five of the complaint, then we would hold that summary judgment was properly granted to Carnation Company.
Affirmed.
