Plain-English Summary
A motion for a supervisory order asks the Supreme Court to step in and use its supervisory authority over something a lower court has done, often as a faster or better-fitting alternative to a full mandamus action. Rule 383 requires the motion to come with explanatory suggestions and the pertinent lower court records or other material needed to present the issue, authenticated the way Rule 328 requires.
The person whose act is being challenged is named as the respondent, but that respondent doesn't have to respond unless the court says so, and staying silent doesn't concede any of the motion's allegations — the party that won below can file documents on the respondent's behalf, just not in the respondent's own name. The prevailing party below then gets a set window to object, and oral argument happens only if the court itself asks for it.

Committee Comments
This procedure is intended to discourage a practice which has developed since 1971 by which parties petition for leave to file a petition for mandamus or, in the alternative, for a supervisory order, in cases in which mandamus would be an inappropriate remedy.
