 (2004)- 8-SCC-706,

 wherein, the Honourable Supreme Court has held as follows:

?......9.The main question which arises for our consideration is whether the decree passed by the trial court can be said to be 'null and 'void'. In our opinion, the law on the point is well settled. The distinction between a decree which is void and a decree which is wrong, incorrect, irregular or not in accordance with law cannot be overlooked or ignored. Where a court lacks inherent jurisdiction in passing a decree or making an order, a decree or order passed by such court would be without jurisdiction non est and void ab initio. A defect of jurisdiction of the court goes to the root of the matter and strikes at the very authority of the court to pass a decree or make an order. Such defect has always been treated as basic and fundamental and a decree or order passed by a court or an authority having no jurisdiction is nullity. Validity of such decree or order can be challenged at any stage, even in execution or collateral proceedings
