No. 05-22-00091-CV IN THE INTEREST OF M.R., A CHILD On Appeal from the 417th Judicial District Court Collin County, Texas

Trial Court Cause No. 417-30026-2019 MEMORANDUM OPINION Before Justices Myers, Osborne, and Nowell

Opinion by Justice Myers It is well-settled that an order is appealable only if either all issues between all parties have been determined or a statute or rule authorizes its appeal. See Jack B. Anglin Co., Inc. v. Tipps , 842 S.W.2d 266, 272 (Tex. 1992). The appealed order here struck appellant’s petition in intervention in the underlying child protection case, but the case has not yet been resolved and no statute or rule authorizes the appeal. See Metromedia Long Distance, Inc. v. Hughes , 810 S.W.2d 494, 499 (Tex. App.—San Antonio 1991, writ denied) (order dismissing or striking petition in intervention is appealable on final judgment).

By letter dated February 15, 2022, we directed appellant to file a jurisdictional letter brief addressing our concern and cautioned her that failure to comply by *2 February 25, 2022 could result in dismissal of the appeal without further notice. To date, however, appellant has not responded. Accordingly, on the record before us, we dismiss the appeal. See T EX . R. A PP . P. 42.3(a).
