O R D E R

After consideration of the briefs and the record on appeal, it appears to the 

Court that: 

(1) The appellant, Frederick Williams, challenges a decision of the 

Superior Court that dismissed his claims against Hockessin Chase, LP and others for 

damages arising out of home-construction defects. For the reasons discussed below, 

we affirm the Superior Court’s judgment.

(2) Williams purchased a house from Hockessin Chase in 2011. In 

December 2017, Williams filed a complaint in the Court of Common Pleas against

Toll Brothers Builders and Michael Brown, alleging that the builder had poorly 
2

constructed, and then poorly repaired, the driveway.

1

 On May 11, 2018, the Court 

of Common Pleas dismissed the action, without prejudice, for failure to name and 

serve the appropriate defendants.2 Specifically, the appellees’ counsel informed 

Williams that Toll Brothers Builders was not a legal entity and that Hockessin Chase, 

LP would be the appropriate defendant; the court also provided Williams with 

information regarding how to serve an entity defendant.

(3) In 2019, Williams filed a second lawsuit in the Court of Common Pleas, 

naming Hockessin Chase, among others, as defendants.3 The complaint sought 

damages for construction defects of the driveway, stucco, roof, and other areas of 

the home. The defendants moved to dismiss, arguing that the Court of Common 

Pleas was not the proper venue, and lacked jurisdiction, because the matter was 

subject to arbitration under arbitration clauses in the sales agreement and home 

warranty contract. On November 1, 2019, the Court of Common Pleas dismissed 

Williams’s complaint, holding that “[p]ursuant to both Section 11 of the purchase 

agreement for the sale of the home and Article VII of the warranty agreement, the

Id. at B-42-43. In a later action, the appellees took the position that the Court of Common Pleas 

also dismissed that first action “for, in part, failure to have jurisdiction over Plaintiff’s alleged 

claims in light of the arbitration clauses within the governing documents.” Williams v. Hockessin 

Chase, LP, C.A. No. CPU4-19-002007, Motion to Dismiss filed Oct. 11, 2019, ¶ 8 (Del. Ct. Com. 

Pl.). In our view, the record, including the Court of Common Pleas order dated May 11, 2018 

(Appendix to Answering Brief, at B-65) and the transcript of the May 11, 2018 hearing (Appendix 

to Answering Brief, at B-27-45), does not support the appellees’ assertion that the Court of 

Common Pleas dismissed the first action based on the arbitration provision.

parties have agreed to resolve any and all claims arising out of the home or home 

warranty through binding arbitration.”

4 Williams did not appeal, but he filed a 

motion that the Court of Common Pleas treated as a motion for reargument and 

denied.5

(4) In June 2020, Williams initiated a new suit in Superior Court, again 

seeking damages for construction defects of the driveway, stucco, roof, and other 

areas of the home. The defendants moved to dismiss, arguing that the complaint was 

barred by res judicata and because the dispute was subject to arbitration.6 The 

Superior Court granted the motion to dismiss, holding that the Superior Court claims 

were barred by the doctrine of claim preclusion because they arose out of the same 

operative facts as the complaint that the Court of Common Pleas had previously 

dismissed. Williams has appealed to this Court.

(5) The Superior Court correctly determined that Williams’s claims were 

precluded by the judgment in the second Court of Common Pleas case. The doctrine 

of claim preclusion, or res judicata, forecloses a party from bringing a second suit 

based on the same cause of action after a court has entered judgment in a prior suit 

involving the same parties.7 The Court of Common Pleas dismissed Williams’s

of Dover Planning Comm’n, 902 A.2d 1084, 1092 (Del. 2006) (“Res judicata operates to bar a 

claim where the following five-part test is satisfied: (1) the original court had jurisdiction over the 
4

claims against Hockessin Chase and the other defendants on the grounds that 

Williams was required to submit the dispute to binding arbitration, and Williams 

neither appealed that decision nor participated in arbitration. The Superior Court did 

not err by dismissing Williams’s Superior Court complaint on that basis.

(6) Williams asserts that binding arbitration was not his only available 

remedy, pointing to the decision in Wang v. Hockessin Chase L.P.

8

In Wang, 

homeowners asserted similar construction-defect claims against Hockessin Chase as 

the claims that Williams has asserted against Hockessin Chase. The Wang

defendants sought dismissal of the homeowners’ claims, as they did of Williams’s 

claims, on the grounds that the sales contract and warranty required the homeowners

to submit the dispute to binding arbitration. The contract and warranty at issue in 

Wang appear to include very similar language regarding arbitration as the Williams 

contract and warranty. On November 9, 2018, approximately one year before the 

Court of Common Pleas determined that Williams was required to submit the dispute 

to binding arbitration, the Superior Court in Wang denied the defendants’ motion to 

dismiss. The court held that it was “unable to interpret the [sales contract and 

warranty] to mean that any action under the Warranty must be resolved by binding 

subject matter and the parties; (2) the parties to the original action were the same as those parties, 

or in privity, in the case at bar; (3) the original cause of action or the issues decided was the same 

as the case at bar; (4) the issues in the prior action must have been decided adversely to the 

appellants in the case at bar; and (5) the decree in the prior action was a final decree.”).

arbitration or that, if another remedy is pursued, the buyer forfeits their rights under 

the Warranty”9 and that “other remedies are a plausible means of dispute 

resolution.”10

(7) Unfortunately, Williams does not appear to have cited Wang while his 

case was pending in the Court of Common Pleas in 2019. And in response to our 

request for supplemental briefing concerning Wang—including our specific request 

to address whether the appellees or their counsel brought Wang to the attention of 

the Court of Common Pleas—the appellees have not indicated that they did so. We 

therefore cannot determine from the record before us whether the Court of Common 

Pleas was aware of the Wang decision or whether the court’s consideration of Wang

would have changed its decision in Williams’s case. Nevertheless, we conclude that 

the judgment in the Court of Common Pleas precluded Williams’s later action in the 

Superior Court. If Williams believed that the Court of Common Pleas overlooked 

Wang, he should have cited it or pursued reargument or an appeal on that basis. 

Indeed, even now, he might possibly seek relief from the Court of Common Pleas

Ch. Mar. 4, 2019) (Appendix to Appellees’ Supplemental Brief, at B-200-05) (dismissing 

Hockessin Chase’s action to confirm an arbitral award, and “agree[ing] with the Superior Court’s 

reasoning and conclusion” that binding arbitration was not the only remedy available to the Wangs

under the contract and warranty).

under that court’s Civil Rule 60(b), but we express no opinion on whether relief 

would be warranted in the circumstances of this case.11

(8) Although we affirm the Superior Court’s judgment, we are troubled by 

the appellees’ counsel’s failure to bring Wang to the attention of the Court of 

Common Pleas in the 2019 case, and we take this opportunity to remind the bar of 

counsel’s obligation to cite adverse authority. Rule 3.3(a)(2) of the Delaware 

Lawyers’ Rules of Professional Conduct provides that a lawyer shall not knowingly 

“fail to disclose to the tribunal legal authority in the controlling jurisdiction known 

to the lawyer to be directly adverse to the position of the client and not disclosed by 

opposing counsel.” Comment 4 to that rule states: 

Legal argument based on a knowingly false representation of law constitutes 

dishonesty toward the tribunal. A lawyer is not required to make a 

disinterested exposition of the law, but must recognize the existence of 

pertinent legal authorities. Furthermore, as stated in paragraph (a)(2), an 

advocate has a duty to disclose directly adverse authority in the controlling 

jurisdiction that has not been disclosed by the opposing party.

Under Rule 3.3, “an attorney should not ignore potentially dispositive authorities”; 

rather, counsel must “cite adverse cases which are ostensibly controlling and then 

may argue their merits or inapplicability.”12

11 Cf. Gibson v. Car Zone, 2011 WL 5354270, at *2 (Del. Nov. 8, 2011) (affirming denial of 

motion under Rule 60(b) where appellant failed to show that opposing counsel had violated Rule 

3.3(a)(2) of the Delaware Lawyers’ Rules of Professional Conduct).

(9) In the supplemental briefing, the appellees contend that they and their 

counsel were not required to cite Wang when seeking dismissal of Williams’s 2019 

Court of Common Pleas complaint because the Wang litigation had not concluded 

and could have been overturned on appeal. They cite no authority for the proposition 

that counsel has no obligation to cite an adverse decision because it might be 

reversed or overturned in the future. This Court has not had occasion to address that 

issue; because of our determination that counsel’s failure to cite Wang does not 

warrant reversal here, we decline to resolve this issue in the procedural posture of 

this case. But we note that courts in other jurisdictions have opined that a lawyer’s 

obligation to cite “adverse authority” extends to authorities from the controlling 

jurisdiction that are “directly adverse to any proposition of law on which the lawyer 

expressly relies” and that “would reasonably be considered important by the judge 

sitting on the case.”13 Thus, “a court decision can be ‘directly adverse’ to a lawyer’s 

position even though the lawyer reasonably believes that the decision is factually 

distinguishable from the current case or the lawyer reasonably believes that, for 

some other reason, the court will ultimately conclude that the decision does not

American Bar Association’s Committee on Professional Ethics and Grievances); In re Greenberg,

Sept. 29, 2015) (“Under Model Rule 3.3, counsel has a duty not only to cite adverse authority but 

also must bring to the attention of the deciding court another court’s ruling against the lawyer’s 

client on the same issue.”); Cicio v. City of New York, 98 A.D.2d 38, 40 (N.Y. App. Div. 1983)

clearly inexcusable” as to two of the adverse cases in which the city was also a party).

control the current case.”14 In short, counsel “have an affirmative obligation to 

advise the court of adverse authorities, though they are free to urge their 

reconsideration.”15

NOW, THEREFORE, IT IS ORDERED that the judgment of the Superior 

Court is AFFIRMED.
