This summary is not the rule. The rule text controls.
If your case doesn't fit neatly into the small claims rules, the court will still have guidance to follow. It will look at Rules 1, 8, 9, 10, 11, 14, 16, and 29 to help decide how to handle the situation.
This basically fills in the gaps. Small claims cases are meant to be simple and faster than regular tax appeal cases, so the rules written just for small claims don't cover every possible situation. When something comes up that isn't addressed, the court borrows from these other listed rules, but only in ways that make sense for a small claims case.
For someone involved in a small claims tax appeal, this means the process might occasionally pull in a procedure from the standard rules. This happens only when needed and only when it fits with how small claims cases are supposed to work, which is simpler and less formal than regular court cases.
