YES BJP CAN DO IT.....             Even with oppostion from congress party LAND ACQUISITION BILL can get through in following 2 ways:1)WITHOUT JOINT SESSION:Considering NDA's majority in LS it will easily sail through the upper house but in RS it will face some stiff resistance ..consider numbers of oppostion parties in RS:CONG-65SP-15TMC-11JDU-12CPM-9NCP-6DMK-4 and some smaller parties have around 7 seats..Also there are 12 nominated members which owe their nomination to UPA so unlikely to support NDASO the opposition stiches to about 125 members...now we can have a look at NDA's situation- BJP: 46- SHS: 3- SAD: 3- RPI (A): 1- Nagaland People's Front: 1- TDP: 6- IND: 1NDA TOTAL SEATS: 60So unless BJP plays some extraordinary politics in breaking SP,TMC & NCP they cannot get through which not likely since all these parties  have a rural voter base so they dont want to appear anti-farmer...also the AIADMK will be key with their 11 member but until now they havent opened up their cards.2)WITH JOINT SESSION:Some of BJP leaders are hinting towards joint session but the only reason they havent called it till now is because they really not sure about their allies which hold key in JOINT SESSION ...consider some scenarios IN CASE OF A JOINT SESSIONTOTAL STRENGTH (LS+RS): 542 + 241 = 783HALFWAY MARK: 392SCENARIO 1:NDA TOTAL STRENGTH: 335 + 60 = 395LAND BILL WILL GET THROUGHSCENARIO 2 (IF PDP AND AIADMK SUPPORTS)NDA TOTAL STRENGTH: 335 + 73 = 408LAND BILL WILL GET THROUGHSCENARIO 3 (IF SHIVSENA, SAD & SWP OPPOSES THE BILL)NDA TOTAL STRENGTH: 312 (LS) + 67 (RS) = 379LAND BILL WILL NOT GET THROUGH           The Shivsena is already unhappy with ministerial portfolios it got  in MAHARASHTRA state government also SAD is not pleased with BJP leaders stance on Drug Menance as well considering PUNJAB state which have large farmer population it is really in some confusion and the SWP walking out (with opposition) have made BJP rethink their stratergy                      So actually not the congress party but the regional parties or to some extent even its allies are stopping BJP from passing LAND ACQUISITION BILL.
