Metro 4 finally cleared; The High Court rejected both the petitions against the project

What exactly was the petition? 

As per the provisions of the Metro Act, although the Central Government is required to appoint a General Manager for the project, no such appointment has been made. So MMRDA has no right to implement this project. Moreover, the land acquisition for this project is illegal and even though the 2034 Draft Development Plan has shown a different path for this project, MMRDA has arbitrarily changed it from time to time, but the land it owns has gone into it, Indo Nippon had alleged. Yashwant Society, a resident organization, had objected that only to save the houses of some big businessmen, MMRDA changed the route of this metro and brought its pillar in front of our society. 

What is the observation of the High Court? 

However, "MMRDA has full authority to implement this project. The central government has the option of appointing a general manager for a metro project. But many state governments have given those powers to the MMRDA under the provisions of the Metro Act. The route was finalized only after the Delhi Metro Rail Corporation came up with the final plan in 2016. A public hearing was also held about it. Why did no one object at that time? Also, the government is not bound to do the land acquisition process only under the Metro Act. So there is no invalidity in this project"the High Court has rejected these petitions by recording the opinion.
