Rule 556 [Reserved]

This rule is reserved, which means it doesn't contain any actual content right now. Courts sometimes set aside a rule number like this to keep the numbering system consistent, even if there's no rule written for it yet.

If you're looking for guidance on this topic, you'll need to check other nearby rules or updates to the Pennsylvania Rules of Appellate Procedure. A reserved rule may be filled in later if the courts decide to add new requirements, but as of now, there's nothing here that affects your case.
