"Is there not an inherent contradiction in the above two rules? If one PRIM can compute a higher law than the other two, surely they're quite likely to disagree with it??"
Maybe I was not clear enough.
Priority (for the CONTROL)
1/FCPC 1 NORMAL LAW
2/FCPC 2 NORMAL LAW
3/FCPC 3 NORMAL LAW
4/FCPC 1 ALTERNATE LAW
5/FCPC 2 ALTERNATE LAW
6/FCPC 3 ALTERNATE LAW
7/FCPC 1 DIRECT LAW
8/FCPC 2 DIRECT LAW
9/FCPC 3 DIRECT LAW
10/FCSC 1 AND/OR* FCSC 2 YAW ALTERNATE/DIRECT LAW
* system setup is different and depends on several configurations.

If one PRIM is not capable of computing a higher law this doesn't mean it is NOT capable of computing a lower law or failed totally.
