2. Siddharth is a techie from global MNC and also a philanthropist. He wants to eradicate hunger in India and he has opened an NGO “Zero Hunger Zero Pain”. The funds utilised by NGOs are regulated by a national law. 40 years back when the law was passed, few NGOs were involving in anti-national activities. Excessive restrictions were placed on fund utilisation and this created many complexities for genuine NGOstoo. The restrictive rules range from substantive provisions that are necessary to regulate utilisation of money by NGOs and also some superfluous, unnecessary technicalities. Recently, it was decided that none of these restrictive provisions are relevant after four decades wherein NGOs have become agents of development and change and government’s desired partners in service delivery. So, the laws are amended and all the unnecessary technicalities are repealed.

You are the Registrar of NGOs. Siddarth files an application to you for funding a food fortification project of his NGO. While auditing, you unearth some discrepancies. In past, some technicalities were not complied with by Siddarth’s NGO. Those technicalities are not at all helpful even in past to regulate errant NGO conduct, they were serving no purpose. But it is a violation of the original unamended law and the NGO funds should be frozen for 8 months, which can affect its development works.

Which one of the following two options will you choose?

  1. Since the law is now amended neither those technicalities have legal force today nor they were necessary in past, you can approve the application of Siddarth.
  2. Though the law is amended today, when it was violated it had legal force in past. So, you can freeze the funds of Siddarth’s NGO.
