The Reason is the soul of the law; when the reason of the law changes the law also is changed.
For the existence of any law, there is a reason behind it. Without that reason the existence of that law is not justified. Thus, when the reason, for the existence of the law changes it is necessary to change the law.
Earlier there such thing such as ‘cyber bullying’ and hence no law existed regarding it. However, with the changing time it was necessary to incorporate ‘cyber bullying’ as an offence. Thus, it is clear that the reason behind law plays a very important role in justifying the existence of the law itself.

Emkay Exports & Anr. v. Madhusudan Shrikrishna:
In the above mentioned case, honorable Bombay High Court noted following:
“We have already indicated that the law in its due course changes its form and application but existence of reasoning with the changing law is a mandatory requirement of judicial process. Ratio est legis anima, mutata legis ratione, mutatur et lex is a maxim for the proposition that law must state reasons and reasons should have a reasonable nexus to the facts of the case. It is said that reason and authority are the two brightest lights of the world and thus it follows that providing of correct reasoning for every decision is the basic feature of rule of law.”
Shikshan Prasarak Mandal vs. State Of Maharashtra:
