Inspired by the Charli XCX album, the “brat summer” trend took the country by storm in the summer 2024. From the radio to fashion to TikTok to even Vice President Kamala Harris’ campaign, “brat” was everywhere. The Collins Dictionary even declared “brat” its 2024 word of the year, defining it as “characterized by a confident, independent and hedonistic attitude.” This spring, the Pennsylvania Supreme Court is poised to hear oral argument in Chilutti v. Uber, 58 EAP 2024. The case concerns, among other things, whether an order staying a case pending arbitration is immediately appealable as a collateral order—a question that asks the court to not only disregard the text of the Pennsylvania Rules of Appellate Procedure but also upend four decades of contrary precedent. With the argument fast approaching, everyone is asking the same question: Is the collateral order doctrine about to have a “brat summer”?
