enforceable against the assessee. In such circumstances, there is no question of issuing fresh notice of demand as claimed. Further, in view of Section 3 of the Taxation Laws (Continuation and Validation of Recovery Proceedings) Act, 1964, the original notice of demand issued by the Income Tax Officer continued to be valid and operative against the assessee. I am of the view that from a combined reading of Sections 156 and 220(2) of the Act, the assessee could not escape from his liability of payment of interest and more particularly, in the light of the legal position, as per the Taxation Laws (Continuation and Validation of Recovery Proceedings) Act, 1964. In other words, the 1964 Act comes to the rescue of the Revenue to hold that the original notice of demand issued by the Income Tax Officer continued to be valid and operative against the petitioner. As rightly observed by the Division Bench in Bharat Commerce and Industries Ltd. V.

I have already concluded that as per the order of the Appellate Tribunal, the original demands stood revived, if that is so, in the absence of payment of entire amount demanded, the respondents are justified in claiming interest under Section 220(2) of the Act. To make it clear even if a part of the amount of tax is outstanding, interest is chargeable from the expiry of 35 days. Even though learned senior counsel for the petitioner very much relied on some of the decisions of the various High Courts as mentioned above, after carefully scrutinising the factual position therein, I am of the view that those cases are either distinguishable or not applicable to the facts of the present case. As a matter of fact, I have already concluded that in most of the cases referred to by learned senior counsel for the petitioner, the assessee in those cases has paid the entire tax demanded, and in some cases, demand arose under
