When someone files a motion in justice court, the judge has flexibility in how to handle it. If the motion relates to certain basic procedural matters (covered under Rules 3 through 71), the judge can simply decide it right away without a lot of extra process. These are usually straightforward requests that do not need a big hearing.
If a motion needs the judge to look at facts or hear evidence before making a decision, the judge gets to choose when that happens. The judge can deal with it at the actual hearing already scheduled for the case, or decide it earlier if that makes more sense. This gives the court room to manage its schedule and handle motions in a practical way.
No matter what type of motion someone files, it has to be properly served on the other side following Rule 5. This means the other party must be officially notified about the motion. The motion also has to follow Rule 11, which covers things like signing the document and making sure it's filed in good faith and not just to cause delay or harassment.
