Sir the case cited by you was quite enlightening however issue in my question is a little bit different from the situation of the cited case as in the referred by me the lessee company has not gone into merger with other company rather some other company has merged into the lessee company and thereafter as a consequence of a condition of scheme of amalgamation, lessee company has changed its name through registrar of companies into the name of the company merging with the lessee company. Now whether in such a situation whether deed of assignment of lease hold rights is required to f executed or not?
