RAP 42(b) Stipulation for premature appeal is a provision of the Federal Rules of Appellate Procedure that allows a court to permit an appeal to be taken from a non-final order in a case if certain conditions are met. This type of stipulation may be used to avoid the delay that may be caused by awaiting the conclusion of the case before an appeal may be taken. RAP 42(b) stipulation for a premature appeal can be divided into two types: stipulation of all parties and stipulation of the court on its own motion. In a stipulation of all parties, all parties to the case must agree to the stipulation of premature appeal. The stipulation must specify the order or part of the order that will be the subject of the appeal and the reasons why the appeal should be taken before the conclusion of the case. In a stipulation of the court on its own motion, the court may allow an appeal to be taken from a non-final order if the court finds that it would be appropriate to do so. The court may consider the same factors that it would consider when deciding whether to allow a stipulation of all parties. Additionally, the court may consider whether the appeal would be more convenient and efficient for the court and whether the appeal would unduly delay the proceedings in the case.
