Aren't you presenting your own 'law' to the courts ie: presenting principles and facts that you are relying upon to support your position/claims etc?
If this assumption is correct, then you provide a maxim or other evidence & if it is not rebutted, it becomes evidence supporting your position...
Similarly, a maxim can be used as a rebuttal of another's position...last man/fact/principle standing wins
