The context of the question is not entirely clear to me, but in general, respect for the rule of law in any country means looking at "applicable law.," which means statutes (or in common law countries, judicial decisions) that have been reached through some established process. Ignoring applicable law in favor of a law/statute that someone deems preferable in some circumstance is a form of lawlessness. Even if it seems like a good idea at the moment, the effect is likely to be transitory if the law is not integrated with "applicable" law. A country that has adopted the ICC will have a statute that specifies definitions and precedence of provisions vis a vis local law.

thank you Inge

The importance of law is such a broad topic it cannot be answered here in a few sentences. Laws are a fundamental method by which a society organizes behavior.

Often laws produce unintended effects and then they are, hopefully, changed. You might look at a basic overview of the topic of "law and economics". The subject of law and economics looks at, among other topics, the effects of law and what will happen if the law is "X" rather than "Y". 

Are you concerned mainly about Article 21 of the Rome Statute:

• Applicable law

1. The Court shall apply:

(a) In the first place, this Statute, Elements of Crimes and its Rules of

Procedure and Evidence;

(b) In the second place, where appropriate, applicable treaties and the

principles and rules of international law, including the established

principles of the international law of armed conflict;

(c) Failing that, general principles of law derived by the Court from national

laws of legal systems of the world including, as appropriate, the national

laws of States that would normally exercise jurisdiction over the crime,

provided that those principles are not inconsistent with this Statute and

with international law and internationally recognized norms and

standards.

2. The Court may apply principles and rules of law as interpreted in its previous

decisions.

3. The application and interpretation of law pursuant to this article must be

consistent with internationally recognized human rights, and be without any

adverse distinction founded on grounds such as gender as defined in article 7,

paragraph 3, age, race, colour, language, religion or belief, political or other

opinion, national, ethnic or social origin, wealth, birth or other status.

If so there is some writing on it.  See the attached abstracts. The Article is at J Int Criminal Justice (2014) 12 (4): 655-679. The SSRN abstract is of a chapter in COMMENTARY ON THE ROME STATUTE OF THE ICC, Otto Triffterer, ed., Hart Publishing, 2008

I found these citations from Google. Not being an internaional lawyer, I think I have reached the limit of my asssistance. Good luck with your searching.
