Brief History: We had some lands in two different villages; lets say A and B. Our ancestors decided to stay in each village and decided to have the land in the village they were living. It was simply a family settlement and the lands were not registered. lets say I'm successor from village A. The successor of village B tried to sell the lands in village A (my village) in 2010; and we filled a "Declaratory suit" in 2010 and also demanding an injunction which was granted. They moved to High court against the order. The high court in 2013 did not revoked the injunction but directed lower court to finish the case in one year. Meanwhile the judge of lower court changed (earlier one got transferred). This new judge allowed their request for "permission to sell the land". We moved to High court against this order because "Selling of Land by them" was our "Cause of Action" for filling the suit in 2010. The high court ruled in our favor setting aside the order of lower court which gave them "permission to sell the land". Now they have filled SLP in supreme court against high court order. Question: Can you please Suggest me what can I do? should I respond in SC our should I wait for one or two hearing? can the SC give them permission to sell the land without intimating us?
