IMPORTANT POINT
When amendment Act was applicable at the time of passing the decree by the appellate Court but it was not noticed, the decree passed is a nullity and appellant is entitled to raise the plea that it was inexecutable in execution proceeding.

ORDER

Leave granted.

2. Substitution allowed.

3. Though the respondent has been served, he is not appearing either in person or through counsel. We have heard the counsel for the appellants. The respondent filed a suit in 1978 for recovery of possession of the land from the appellants on the basis of a declaratory decree obtained by one Nathu in the year 1924 as a collateral on the basis of the custom. It is their case that the appellant had purchased the property from Rulia who is an alienator to Nathu and under the custom he was nearest collateral and this alienation was not supported by consideration . On appeal, dismissal of the suit by trial Court met reversal. The Second Appeal was dismissed in RSA No. 2416/79. In execution the appellant took the plea that since the customary right had been taken away by an amendment made later, the decree passed by the trial Court is a nullity. That application was negatived and in the impugned order dated January 30, 1992 the High Court dismissed the revision. Thus this appeal by special leave.

4. The controversy is no longer res Integra. This Court in Darshan Singh v. Ram Pal Singh1 considered the effect of-the Amendment Act 1973 on the customary right of the Punjab Custom (Power to Contest) Act, 1920 and held that :

"Considering the above principles, the provisions of the Principal Act, the statement of object and reasons and the provisions of the Amendment Act and the decisions of Punjab High Court and of this Court, we are of the view that Section 7 of the Principal Act as amended by the Amendment Act is retrospective and is applicable to pending proceedings. The decisions of this Court dated 28.11.1986 in Ujaggar Singh v. Dharam Singh (Civil Appeal No. 1263 of 1973) and in Udham Singh v. Tarsem Singh (Civil Appeal No. 1135 of 1974) dated 15.7.1987 do not need reconsideration.

In course of the arguments it transpired that some of the appellants might have had right to contest the alienations under the Hindu Law. Doubts have been expressed as to whether after these appeals are dismissed any such claim would be, tenable in law inasmuch as, it is submitted, the right under the Principal Act was a statutory right which has now been taken away. The answer to the question would depend on what resulted when the Punjab Laws Act and the Principal Act were passed. There appears to be no doubt that by the former the customs were preserved and by the latter the customary right to contest alienation was regulated. This would be clear from the following analysis.

However, the intention of the legislature and the provisions of the statute have to be carefully examined to ascertain the result. "An Act of Parliament which recognises the existence and validity of a custom may not operate to create new statutory rights in favour of the persons or classes of persons who might formerly have benefited by the custom. Such a statute may merely have the effect of sanctioning the validity of the custom as a custom, without merging the custom in the higher title by statute."

In the instant case we are of the view that the custom was confirmed and regulated by the Punjab Laws Act and the Principal Act and it was done away with by amendment Act. No statute was passed on the basis of the custom- itself so as to transform the custom itself into a higher statutory right. Therefore, either before or after the custom has been done away -with by the Amendment Act, the rights of the parties under Hindu Law remain unaffected and will provide the rule of decision where alienations are contested under Hindu Law. It was observed by Robertson, J. in Daya Ram v.Sohel Singh, 110 PR (1906) 390 that "in all cases under Section 5 of the Punjab Laws Act, it lies upon the person asserting that he is ruled in regard to a particular matter by custom, to prove that he is so governed, and not by personal law, and further to prove what the particular custom is. There is no presumption created by the clause in favour of custom; on the co
