This summary is not the rule. The rule text controls.
When you file a case that goes straight to the Oklahoma Supreme Court instead of starting in a lower court, Part VI of the court rules controls how that case works. This is called "original jurisdiction," and it covers situations where the Supreme Court is the first and only court to hear the matter, rather than reviewing a decision made by a lower court.
There's an exception, though. If another Supreme Court rule specifically says a different set of procedures applies to a certain type of case, that other rule takes priority over Part VI. So you need to check whether your specific type of case has its own special procedure before assuming Part VI covers everything.
Along with Part VI, Part I of the rules also applies to these cases, plus any other rules that get specifically mentioned as relevant. In short, several parts of the rule book work together, and you may need to look at more than one section to understand the full set of steps for your case.
