At the appellate level, “‘[a]n appellant can, of course, abandon some of the
issues raised below and stand here on a narrower ground.’” Harmon v. State Roads
Comm’n, 242 Md. 24, 30 (1966) (quoting Weil v. Free State Oil Co. of Md., 200 Md. 62,
66 (1952)). “This Court has consistently held that a question not presented or argued in
an appellant’s brief is waived or abandoned and is, therefore, not properly preserved for
review.” Health Servs. Cost Rev. Comm’n v. Lutheran Hosp. of Maryland, Inc., 298 Md.
651, 664 (1984). See Rosales v. State, 463 Md. 552, 569–70 (2019). In fact, we “may
dismiss an appeal “or make any other appropriate order with respect to the case” for a
party’s failure to comply with the rule. Md. Rule 8–504(c).” Klauenberg v. State, 355
Md. 528, 552 (1999).
Conversely, Maryland Rule 8–131(a) “‘grants the appellate courts of this State
discretion to review any unpreserved issue.’” Nat’l Union Fire Ins. Co. of Pittsburgh,
PA. v. Fund for Animals, Inc., 451 Md. 431, 466–67 (2017) (quoting Jones, 379 Md. at
715, 843 A.2d at 784–85). However, while an appellate court has the discretion to raise
collateral estoppel sua sponte, there is no requirement for the appellate court to do so.
See Ritchie v. Donnelly, 324 Md. 344, 375 (1991) (holding that where the “Court of
Special Appeals in this case could have, in its discretion, considered the arguments” that
the plaintiff failed to address in her opening brief, the Court’s “refusal to do so, however,
was not an abuse of discretion.”). Collateral estoppel is not a jurisdictional issue that the
court must address where it is not promulgated by the parties, and unlike lack of
jurisdiction, does not survive a failure of a party to plead. See Fund for Animals, Inc.,
451 Md. at 464.
Appellate courts also have the discretion to raise the related issue of res judicata
sua sponte. Anne Arundel Cnty. Bd. of Educ. v. Norville, 390 Md. 93, 105 (2005) (citing
Arizona v. California, 120 S. Ct. 2304, 2318, supplemented, 121 S. Ct. 292 (2000) for the
proposition that the exercise of an appellate court’s discretion to dismiss an action sua
