When a petition in error is timely filed, the Supreme Court shall have jurisdiction of the entire action that is the subject of the appeal. No additional jurisdictional steps shall be necessary to enable the Supreme Court to rule upon any errors made in the trial of the action which are asserted by any party to the appeal and involve any other party to the appeal.
The Supreme Court may prescribe by rule the time limits for filing counter-appeals and cross-appeals.

Added by Laws 1984, HB 1454, c. 31, §1, eff. 11/1/1984.
Plain-English Summary
Once a petition in error is filed on time, the Supreme Court's jurisdiction isn't limited to the specific ruling the appellant flagged — it reaches the entire action under appeal. No party needs to take any extra jurisdictional step to get the court to rule on trial errors that party raises, as long as those errors involve another party to the appeal.
The section also lets the Supreme Court set, by rule, its own deadlines for counter-appeals and cross-appeals, rather than leaving that timing to case-by-case litigation.
Frequently Asked Questions

No — the section says no additional jurisdictional steps are necessary once the petition in error has been timely filed.
Where do the deadlines for cross-appeals and counter-appeals come from?
The Supreme Court prescribes them by rule under authority this section grants.
