Geoffrey Charlton appeals the dismissal of appellee Mond for lack of personal jurisdiction, as well as a grant of summary judgment on his contract and civil conspiracy claims against appellee Mesquita. Because Charlton fails to identify any error by the trial court or present a legal basis to justify reversal on any other ground, we affirm.
I. Factual Summary
This case comes before us after a six-year long course through the Superior Court. In 2002, appellee Mond engaged appellant Charlton to renovate his home. Appellee Mesquita worked as Charlton’s carpentry sub-contractor on various projects, including the Mond home. Charlton fired Mesquita on July 10, 2002. Mond terminated Charlton’s contract in September 2002. Charlton then sued Mond and Mesquita for breach of contract, civil conspiracy and defamation. He alleged that Mesquita spread “hateful false information ... for the purpose of destroying [Charl-ton’s] contractual relationship^],” first to Mond and later, in conjunction with Mond, to Charlton’s other business associates.
Mond, a Maryland resident, filed a motion to dismiss for lack of personal jurisdiction, which the trial court denied. Thereafter, Mond filed a counterclaim, along with a motion to reconsider the denial of the motion to dismiss, which the trial court again denied. Mesquita also counterclaimed. Fourteen months later, after discovery was concluded, the trial court granted summary judgment to both Mond and Mesquita on the breach of contract and conspiracy claims, but denied summary judgment on the defamation claim and the counterclaims. At the same time, the court allowed Mond to file supplemental briefs on the jurisdictional issue. Charlton voluntarily dismissed his remaining defamation claim against Mesquita without prejudice but continued to pursue his claim against Mond. Meanwhile, Mond once more renewed his motion to dismiss for lack of personal jurisdiction, which the court finally granted. Later, a jury trial solely on Mesquita’s counterclaim took place, with the jury returning a verdict for Mesquita.
Charlton contends that the trial court erred in ruling that it had no jurisdiction over Mond and asserts that Mesquita should not have been granted summary judgment. He also alleges that “the orders and judgments issued by the trial court were plainly erroneous, plainly defective, and/or contrary to law.” 1
We review both dismissal and summary judgment de novo. 2 Charlton bases his claim that the Superior Court had personal jurisdiction over Mond solely on records of telephone calls between Mond and Mesquita, neither of whom is a District of Columbia resident, as well as between Mond and other parties who are District residents. Mond made the calls prior to and on the day he terminated Charlton’s contract. Charlton urges us to interpret these telephone records in the light most favorable to him 3 and to conclude that they constitute sufficient grounds for personal jurisdiction over Mond. Alternatively, he argues that Mond waived his jurisdictional defense by filing a counterclaim. We hold that jurisdiction was improper in the first instance and that the trial judge erred in denying Mond’s first motion to dismiss. We also hold that when a defendant first files to dismiss and the court denies the motion, the defendant does not waive an objection to the court’s jurisdiction by later filing a counterclaim.
A. The Superior Court lacked personal jurisdiction over Mond.
Charlton relies on the Restatement (SeCOnd) of Torts § 577(1) (1977)
4
to support the proposition that “the situs of the defamation, venue and jurisdiction, is (sic) where the defamatory information was received.” Though the situs of the alleged injury was certainly in the District because the allegedly defamatory material reached some who were indisputably District residents, we have found no case that would allow personal jurisdiction over Mond based solely on that fact. Nor do the cases Charlton relies upon support this position.
5
Had Charlton claimed personal jurisdiction over Mond as one who “caus[ed] tortious injury in the District of Columbia by an act or omission
in
the District of Columbia,”
6
his argument would have had more merit. But he cannot so argue, since Mond’s phone calls originated in Maryland. Instead, Charlton must prove jurisdiction
7
under D.C.Code
Because there is no basis for personal jurisdiction based on the phone calls themselves,
9
Charlton needed to prove additional contacts between Mond and the District of Columbia. But even after discovery had been completed, Charlton failed to present evidence of any such contacts. The cases that Charlton relies on fail to support his argument.
10
The closest case on point is
Blumenthal v. Drudge,
where the court held that jurisdiction existed over Drudge, a California resident who was accused of defaming a White House staffer by publishing a story about him on his web site.
11
In holding so, however, the court did not rest its decision solely on the fact that the defamatory story was available to or directed at District of Columbia residents. Instead, it concentrated on the additional multiple and persistent contacts between the defendant and the forum.
12
Charlton misinterprets
Drudge
when he argues that any defendant who “knows the effect of his actions will be suffered in a particular forum ... should also expect to be brought into court there.”
13
Here, both Charlton and Mond were Maryland residents. Charlton’s business was registered in Maryland. The contract was negotiated and executed in Maryland.
B. Mond did not consent to the jurisdiction of the court by filing a counterclaim.
Charlton also argues that Mond’s counterclaim constituted a waiver of his jurisdictional objection. He relies on Overby v. Barnett, where the trial court sua sponte dismissed a contract claim pursuant to an arbitration provision after the defendants had filed a counterclaim. 14 In Over-by, we held that the parties waived their right to arbitrate by filing the counterclaim, and that the trial court had erred by dismissing for lack of jurisdiction. But Overby is not on point because it addressed the subject matter jurisdiction of the court. 15 Here the issue is personal jurisdiction over Mond. Though Charlton fails to convince us that the counterclaim signified Mond’s consent to the power of the court, the issue warrants further analysis.
Though Charlton fails to cite them, our precedents hold that filing a counterclaim operates as a waiver of an objection to personal jurisdiction.
16
The waiver does not depend on whether the counterclaim was permissive.
17
Thus, Mond’s argument that he had “no choice but to file a counterclaim ... to avoid res judicata and statute of limitations issues in Maryland” lacks merit. Nevertheless, we are convinced that there was no waiver here. First, we note that in every case that we could find which has addressed this issue, defendants raised a jurisdictional defense
after
counterclaiming, unlike Mond, who objected to the court’s lack of jurisdiction
before
filing a counterclaim.
18
In addition, as we have already explained, the trial court erred when it denied Mond’s original motion to dismiss.
19
Moreover, Mond could have properly moved to dismiss for lack of personal jurisdiction
concurrently
with filing a counterclaim without affecting a waiver.
20
Finally, we have suggested that a denied motion to dismiss preserves the jurisdictional issue on appeal, even when the defendant counterclaims in the interim.
21
III. The contract and civil conspiracy claims
The trial court disposed of Charl-ton’s contract and civil conspiracy claims by granting Mesquita’s motion for summary judgment. 24 We agree that no reasonable juror could find for Charlton on the breach of contract claim because Mes-quita was not a party to either of the contracts between Mond and Charlton. Non-parties owe no contractual duty to the contracting parties. 25 Therefore, the trial court properly granted summary judgment to Mesquita with respect to the contract claim.
With respect to the conspiracy claim, Charlton argues that “Mond’s phone records and [Charlton’s own] affidavits,” as well as “the presence of Mesquita at Mond’s home ... raise strong inferences of genuine issues of material fact as to the existence of a conspiracy.” Charlton, however, does not cite a single case to support his position. The sum of his evidence of a conspiracy (apart from his own affidavits) are phone records indicating that Mond made phone calls to Mesquita and other parties. Charlton failed to furnish any other evidence of the agreement, if any, appellees reached when they contacted each other. Despite having ten months to conduct discovery, Charlton did not even depose Mond or Mesquita 26 Lacking any evidence, Charlton now asks “[w]hat else could they have been talking about?” Such conclusory conjecture does not carry Charlton’s burden of proof and does not suffice to overcome summary judgment. 27
IV. The defamation claim
Charlton voluntarily dismissed his remaining defamation claim against Mes-quita without prejudice. He now claims that the trial court misconstrued his motion to dismiss, which was meant to include Mesquita’s counterclaim as well as his own claims. He asserts that the trial court failed to grant the relief he requested. The trial judge’s order does show that she re-wrote the requested relief. This does not suffice, however, to prove that the judge misconstrued the relief Charlton sought. Almost all of the judge’s previous orders exhibit corrections and writings in her own hand. At most, this shows that the trial judge made last minute changes
In conclusion, because the trial court lacked personal jurisdiction over appellee Mond and since Charlton can show no other error by the trial court, we
Affirm.
