This summary is not the rule. The rule text controls.
When a case gets moved from the Supreme Court or County Court to a District Court, the District Court doesn't just put it at the back of the line. Instead, the court tries to give the case a spot on the calendar based on when it was originally set for trial in the court it came from.
In simple terms, the case keeps its place in line. If the note of issue (the paperwork that puts a case on track for trial) was filed on a certain date in the original court, the District Court tries to treat the case as if that same filing date applied there too. This means people don't lose their spot in the queue just because their case was transferred to a different court.
The goal is fairness. Someone whose case gets moved shouldn't be pushed to the back and forced to wait longer than they would have if the case had stayed in its original court. The District Court does its best to slot the case in where it would naturally fall based on that original timing.
