This case has been decided. See how it turned out!
Because the judicial system doesn’t have endless resources, the Supreme Court must decide cases like this one.
Procedural cases often do not catch the mainstream news because they deal in abstract concepts. The issue in this case is not about a Constitutional right, or something we can see or feel (a gun, a search, or discrimination). This case is about a court rule and a concept we don’t think about much.
The concept here is judicial economy. Our courts can’t waste their efforts. We can’t have two different courts trying the same exact case. That would be a waste. Sometimes similar or related cases are consolidated so the judicial effort can be multiplied.
