Has moral ever give birth to law or better put, source of law making? Is any there mutual relationship between the two? Political analysts and law luminaries in the house, lets make this educative.

Law has to conform with the moral standard of a given society. In other words, a law that advocates immorality is not good law.

However, one may want to ask; what then is morality?
What is morally just or otherwise can be seen from a reasonable man's perspective, i.e what at average man in the society would see as morally just.

In my humble view therefore, what we see as morality may vary from place to place depending on the moral standards of each place. The law must also reflect this moral standard.
