   Official Note

   Rule 313 is a codificatioin of existing case law with respect to collateral orders. See Pubar v. Greco, 483 Pa. 68, 73, 394 A.2d 542, 545 (1978) (quoting Cohen v. Beneficial Industrial Corp., 337 U. S. 541 (1949)). Examples of collateral orders include an order denying a pre-trial motion to dismiss based on double jeopardy, Commonwealth v. Brady, 510 Pa. 363, 508 A.2d 286, 289—91 (1986) (allowing an immediate appeal from denial of double jeopardy claim under collateral order doctrine where trial court makes a finding that motion is not frivolous); an order denying a petition to permit the payment of death taxes, Hankin v. Hankin, 338 Pa. Super. 442, 487 A.2d 1363 (1985); and an order denying a petition for removal of an executor, Re: Estate of Georgianna, 312 Pa. Super. 339, 458 A.2d 989 (1983), aff’d, 504 Pa. 510, 475 A.2d 744. Thorough discussions of the collateral order doctrine as it has been applied by Pennsylvania appellate courts are found in the following sources: Darlington, McKeon, Schuckers and Brown, 1 Pennsylvania Appellate, Practice Second Edition, § §  313:1-313:201 (1994) and Byer, Appealable orders under the Pennsylvania Rules of Appellate Procedures in Practice and Procedures in Pennsylvania Appellate Courts (PBI No. 1994-869); Pines, Pennsylvania Appellate Practice: Procedural Requirements and the Vagaries of Jurisdiction, 91 Dick. L. Rev. 55, 107—115 (1986).

   If an order falls under Rule 313, an immediate appeal may be taken as of right simply by filing a notice of appeal. The procedures set forth in Rules 341(c) and 1311 do not apply under Rule 313.
