This summary is not the rule. The rule text controls.
Sometimes a person needs to preserve testimony before a lawsuit is fully underway, often because a witness might not be available later due to age, illness, or other reasons. This rule makes clear that courts still have the power to allow this kind of action, even outside the specific steps laid out elsewhere in the rules.
In simple terms, this rule protects a court's ability to let someone lock in a witness's statement through a formal legal action, using whatever authority the court already has. It does not create new steps or requirements. It just confirms that this option remains available and is not blocked or limited by other parts of the rules on perpetuating testimony.
For someone involved in a case, this means there is more than one way to get testimony preserved ahead of time if there is a real risk of losing it. Courts are not boxed in by narrow procedures, and they can still use their broader legal power to make sure important testimony is saved for later use.
