C. made a ruling regarding border wall construction. The case involved a Native American tribe's reservation.

A certain number of miles of wall are planned for the area. The tribe had requested that the construction be halted, but this request was denied. The judge's decision was based on the idea that the tribe had not proven a certain point about the wall's impact.
