That which is equitable and good is the law of laws.

Explanation

The ultimate test of any legal rule is whether it produces what is equitable and good — a rule that consistently fails this test has lost its claim to authority.

Where this applies

• A legal rule consistently produces unfair outcomes and someone challenges it.
• The test of whether a law is valid is whether it produces good and equitable results.
