Either under the proviso as it originally stood or under the new separate paragraph enacted by way of an amendment the legislative intent was and is quite clear that only suits and original proceedings between a landlord and a tenant (of the description or categories specified 1062 therein) which were pending on the relevant date are required to be decided and disposed of by applying the provisions of the 1947 Act while execution proceedings and appeals arising out of decrees or orders passed before the coming into operation of the Act are denied the benefits of the provisions of the Act and have been directed to be decided and disposed of as if this Act had not been passed, that is to say, such execution proceedings and appeals would be continued to be governed by and shall be disposed of in accordance with the law that was then applicable to them In other words, it is clear that the proviso was and has been enacted to provide for special savings which suggests that it has not been introduced merely with a view to qualify or create exceptions to what is contained in the substantive part of section 50.
