As an extremely lawful deity, Amaunator followed the letter of the law rather than its spirit. If something was not prohibited by law, then it was permitted, and there could even be multiple interpretations.
To Borne, the Nether Inspectorate's laws were laughably simple. He had thoroughly studied Nether's laws in just three months, including every written regulation beyond the Academy.
In truth, few people besides legal scholars specifically studied the law. Nether worshipped quite a few deities, and many laws had in fact been adapted from temple rules, all meant to better promote their respective doctrines.
This had made Nether's laws incredibly chaotic, yet everyone had somehow remained at peace.
Though they sometimes argued their case on principle, they were restrained most of the time. Unlike the gods of later eras, they did not personally descend into the fray to fight to the death.
The gods were still fairly harmonious with one another. Even Amaunator, the Lord of Radiance, had a rather good relationship with Jergal, the god of death. In Nether, one could occasionally see paladins and mummy priests enforcing the law together.
If the big shots got along, then those beneath them naturally had to uphold that relationship as well. Even if their doctrines conflicted, it only meant that you did not understand the doctrines thoroughly enough!
That was how bizarre laws such as "presumption of guilt" and "prove your own innocence" came about. As long as you could explain away the problem and make the logic consistent, even a capital offense could result in an immediate acquittal in court!
Naturally, the prerequisite was having sufficient knowledge of doctrine and law.
To Borne, the method used to frame Cook was ridiculously low-level. He could not even be bothered to look at it; it was no more than elementary-school-level
