I have to say yes to all your questions. As advised by Mr.Raju, any aggrieved party may approach the DRT under section 17 of the SARFAESI Act. Any aggrieved party includes a tenant also.
I would like to differ from the views of Mr.Khalid Masood - When a petition under section 14 is filed before a CJM or DM or CMM, he should see whether the notice under section 13(2) of the SARFAESI Act is served on the borrower and whether the secured property comes under his jurisdiction. If he is satisfied by both the above mentioned things he his duty bound to pass the possession order. Most of the high courts have viewed the same. Some High Courts are of the view 13(4) should proceed section 14, but the law is still not settled.
Request the views of other members also.
