In a civil case pending in federal court, a party’s timely filing of any specified post-judgment motion will serve to postpone the deadline applicable to all parties for filing a timely notice of appeal until at least 30 days from the date on which the federal district court disposes of the post-judgment motion.

Assume, hypothetically, that a federal district court has entered a final judgment in a civil case on August 1. Assume further that the deadline for filing a timely appeal would therefore be August 31. If any of the parties to that suit filed a timely motion to alter or amend the judgment under Federal Rule of Civil Procedure 59(e), the deadline for filing a timely notice of appeal would then be postponed until 30 days after the district court entered an order disposing of that motion.
