49. Though, the Claimant has vehemently opposed the plea of the Respondent and vociferously asserted that the ATS does not require any registration and in support of the said contention, the Ld. Counsel for the Claimant emphasized that the nomenclature of a document or agreement is immaterial and it is the intention of the parties which is to be seen by the Tribunal for deciding the nature of transaction. I am not inclined to agree with the said proposition advanced by the Ld. Counsel for the Claimant as there is nothing in the ATS which even remotely suggests that the intention of the parties was not to purchase the Suit Property but was only to get the lease or sub-lease. The word ‘Ownership’ in Section 54 of TPA refers to the ownership of tangible or intangible immovable property. Ownership means bundle of rights allowing one to use, manage, and enjoy property, including the right to convey it to the other. A bare reading of Section 54 of TPA would show that whenever a person is transferring all his right and interest in any tangible or intangible immovable property to another person then it will amount to 'Sale' within the meaning of Section 54 of TPA. The immovable property is defined under TPA as ‘immovable property does not include standing timber, growing crops or grass’ as well as under Registration Act as “Immovable Property includes land, buildings, hereditary allowances, rights to ways, lights, ferries, fisheries or any other benefit to arise out of land, and things attached to the earth, or permanently fastened to anything which is attached to the earth, but not standing timber, growing crops nor grass” and General Clauses Act, 1897 as “immovable property shall include land, benefits to arise out of land, and things attached to the earth, or permanently fastened to anything attached to the earth”. A bare perusal of these definitions shows that any interest or benefit arising out of land is an immovable property. In view of law laid down in Md. Mobarak Hussain (Supra), Kanhaiya Lal (supra), Phoola Bhanna (Supra) and Kandkuri Anthya (Supra) even the leasehold rights possessed by the Respondent is an immovable property. Transfer/Sale of leasehold or sub-leasehold rights without reserving any right by the Respondent would amount to ‘Sale’ within the meaning of section 54 of TPA and any contract for transfer/sale of such leasehold or sub-leasehold rights will be a contract for sale within
