Section 3/7 - Essential Commodities Act

Dear Sir/Mam, Just a short summary of the event. My friends father and his grand father opened a petrol station (pump) in UP many many years ago. Around 2002, friends father left the business and opened a new business due to some family issues. My friends father has no link with that petrol station from past 15 years. They have a document from companies secretary proving that my friends father holds no share in that firm from past 15 years. Moreover my friends uncle who was taking care of the petrol station sold it to one of his known on a mutual agreement and says he has no proof that he has sold the petrol station. FIR has been filed against my friends father, grand father and grand mother under section 3/7. The FIR was lodged by the Weights and Measures department under their name because the license of the petrol station is still under their name, which ideally should have been transferred to the uncle or the new owner but that never happened. What is the best option here to avoid the arrest as we have heard it is a non bailable offence for 6 months. Or how can we get their names removed from the FIR stating the fact that they have no link with the petrol station apart from the license being in their names. Your help will be highly appreciated and it is a urgent matter so please consider that as well, Thanks, Tinu
