LETTER OPINION AND ORDER

Re: ScriptSourcing, LLC, et al. v. Continental Casualty Company Civil No. 26-cv-00559-JRR

Dear Counsel: This letter concerns multiple discovery disputes raised by the parties: the proper scope of discovery, the timing of certain discovery, and the adequacy of Defendant’s discovery responses. See ECFs 20-21, 25-26. On July 28, 2026, Judge Rubin referred this matter to me for all discovery. ECF 22. On August 5, 2026, the Court held a telephone conference with the parties after receiving their letters reflecting the disputes and requesting a pre-motion conference. See ECF 24. At the conclusion of the conference, upon the parties’ request, the Court directed the parties to file brief submissions—no longer than five pages—addressing the various disputes mentioned during the teleconference. Id. The parties timely filed their submissions in accordance with the deadlines. ECFs 25, 26. Having reviewed the supplemental correspondence, the Court finds no additional hearing necessary and addresses the disputes in this letter opinion. See L.R. 105.6 (D. Md. 2025). Plaintiff ScriptSourcing provides clients with “advice and strategies regarding how the client can save money in the implementation of their prescription drug plan.” ECF 25, at 1. Plaintiff Gary Becker is the CEO and sole employee of ScriptSourcing. Id. Plaintiffs purchased a professional liability policy from Continental Casualty Company (“Defendant”); this policy provides coverage for damages arising from Plaintiffs’ professional services, specifically “consulting services.” Id. In an underlying, related case, ScriptSourcing and Becker (among others) are defending against allegations concerning the importation and sale of foreign prescription medications. Gilead Sciences, Inc. et al. v. Meritain Health, Inc. et al, No. 24-cv- 03566-JRR (filed Dec. 10, 2024). Plaintiffs claim that the wrongful acts they are accused of arise from “consulting services” that are covered by the insurance policy. ECF 25, at 1. In filing the present declaratory judgment action, Plaintiffs seek declaration that Defendant, as their insurer, has a duty to defend them in the underlying Gilead case. See ECF 1. The dispute letters raise multiple issues, and the discussion on the conference call identified others. Thus, the parties’ submissions address three matters: (1) whether Defendant is entitled to discovery of any “extrinsic evidence” concerning whether a duty to defend exists (and, relatedly, the sufficiency of Plaintiffs’ responses to certain discovery requests), (2) when Plaintiffs must provide discovery concerning the alleged damages in this case, e.g., defense counsel’s invoices in connection with Gilead, and (3) whether Defendant’s responses to fact interrogatories by referencing other records is proper. The Court will address each of these in turn. September 4, 2026 Page 2

A. DUE TO THE “EIGHT CORNERS” RULE, DISCOVERY ON EXTRINSIC EVIDENCE IS NOT PROPORTIONAL TO THE NEEDS OF THE CASE ABSENT SOME ARGUMENT OR OTHER INDICATION THAT A CONTRACTUAL AMBIGUITY EXISTS. Defendant claims that Plaintiffs “have refused to respond to numerous interrogatories and document requests on the basis that they should not be required to provide anything they consider extrinsic evidence, encompassing anything beyond the underlying complaint and the insurance policy[.]” ECF 26, at 1. Defendant argues that the Federal Rules of Civil Procedure are broad and allow it to seek any information that is reasonably calculated to lead to the discovery of admissible evidence, which includes anything relevant to its defenses. Id. Plaintiffs counter that in determining whether an insurer has a duty to defend, Maryland law follows the “eight corners rule,” rendering much of Defendant’s requested information unnecessary to resolve the merits. ECF 25, at 2.

In Maryland, the “eight corners rule” commands that “only the underlying complaint and the insurance policy could be consulted to determine the potentiality of coverage.” Cowan Sys., Inc. v. Harleysville Mut. Ins. Co., 457 F.3d 368, 372 (4th Cir. 2006). In applying this rule, courts engage in a two-step inquiry to assess whether an insurer has a duty to defend. Id.; N. Ins. Co. of New York v. Baltimore Bus. Commc’ns, 68 F. App’x 414, 417 (4th Cir. 2003). First, the court must determine “what is the coverage and what are the defenses under the terms and requirements of the insurance policy[.]” Cowan Sys., 457 F.3d at 372 (quoting Montgomery Cnty. Bd. of Ed. v. Horace Mann Ins. Co., 383 Md. 527, 538, 860 A.2d 909 (Md. 2004)); Northern Ins., 68 F. App’x at 417 (“the court must first determine the extent of insurance coverage by reviewing the policy’s terms, conditions, and requirements”). Second, the court must determine whether “the allegations in the [underlying] tort action potentially bring a tort claim within the policy’s coverage[.]” Cowan Sys., 457 F.3d at 372 (quoting Horace Mann Ins., 383 Md. at 538, 860 A.2d 909); Northern Ins., 68 F. App’x at 417. “If a potentiality for coverage exists, the insurer is obliged to defend its insured even though the cause of action cannot possibly succeed, either in law or in fact.” Northern Ins., 68 F. App’x at 417 (citing Brohawn v. Transamerica Ins. Co., 276 Md. 396, 408, 347 A.2d 842, 850–51 (Md. 1975)); see also Cowan Sys., 457 F.3d at 372 (“[A]ny doubts about the potentiality of coverage must be resolved in favor of the insured.”) (citing Walk v. Hartford Cas. Ins. Co., 382 Md. 1, 16, 852 A.2d 98, 106-07 (Md. 2004)).

The impact of the rule is straightforward: “in deciding whether to defend, an insurer may only rely on the language of the policy and the facts alleged in the complaint, and not on outside evidence, as that would risk deciding the question on facts not advanced in the underlying action.” Cowan Sys., 457 F.3d at 372 (observing that the “asymmetrical prohibition on the use of extrinsic evidence by the insurer” prevents a reliance on outside evidence that “would risk deciding the [coverage] question on facts not advanced in the underlying action”) (citing Aetna Cas. & Sur. Co. v. Cochran, 337 Md. 98, 111, 651 A.2d 859, 866 (Md. 1995)). “The rule against permitting the insurer to utilize extrinsic evidence seems to serve several interests. Most notably, it precludes the insurer from circumventing the potentiality rule by attempting to litigate the merits of an underlying lawsuit in the coverage action; any potentiality for coverage triggers the duty to defend.” Northern Ins., 68 F. App’x at 418. The Fourth Circuit explained that extrinsic evidence September 4, 2026 Page 3

may only be used in two instances: (1) where the underlying tort plaintiff amended its allegations against the insured; and (2) if there is uncontroverted extrinsic evidence from the underlying lawsuit that clearly establishes that the allegations are beyond the scope of coverage. Id. at 418.1
