Within how many days, an appeal can be made by an aggrieved person by decision of the National Green Tribunal to the Supreme Court ?

The correct answer is (D) Ninety days.

• Under Section 22 of the National Green Tribunal Act, 2010, any person aggrieved by an award, decision, or order of the National Green Tribunal (NGT) may file an appeal to the Supreme Court of India.
• The law mandates that such an appeal must be filed within a period of 90 days from the date of communication of the award, decision, or order to the aggrieved person, provided the Supreme Court may entertain an appeal after the expiry of the said 90 days if it is satisfied that the appellant was prevented by sufficient cause from preferring the appeal.
• Options (A) 30 days, (B) 45 days, and (C) 60 days are incorrect as they do not align with the statutory limitation period prescribed under the NGT Act for approaching the Supreme Court; these periods are often associated with other appellate forums or lower court procedures under the Limitation Act.
