This summary is not the rule. The rule text controls.
If you're dealing with a case where a trial court has ordered a mandate of funds (basically a court order requiring money to be paid or set aside, often used against government bodies to fund court operations), the process for taking that case to the Indiana Supreme Court starts under Trial Rule 60.5(B). That trial rule lays out the specific steps you need to follow to get the case in front of the Supreme Court in the first place.
Once the case is properly before the Supreme Court, there's no fixed roadmap for how it will proceed. Instead, the Supreme Court decides on its own how the appeal will move forward. This means the Court will issue its own orders about things like when briefs are due, whether oral argument will happen, and what other procedural steps are needed.
In short, this rule tells you where to start (Trial Rule 60.5(B)) but leaves the rest of the process flexible. The Supreme Court has discretion to handle these mandate of funds appeals in whatever way makes sense for that particular case, rather than following the standard appellate procedure used in most other appeals.
