and the right to make assessment gets extinguished. Therefore, there would be no question of extending the time for assessment when the assessment has already become time barred. A valuable right has also accrued in favour of the assessee when the period of limitation expires. If the Commissioner is permitted to grant the extension even after the expiry of original period of limitation prescribed under the Act, it will give him right to exercise such a power at any time even much after the last date of assessment. In the instant appeals itself, when the last dates of assessment were 30th April, 2004, 30th April, 2005, 30th April, 2006 and 30th April, 2007, order extending the time under Section 11 (10) of the Act were passed on August 17, 2007, August 17, 2007, August 17, 2007 and May 25, 2007 respectively. Thus, for the Assessment Year 2000-2001, order of extension is passed more than three years after the last date and for the Assessment Year 2001-2002, it is more than two years after the last date. Such a situation cannot be countenanced as rightly held by the High Court. When the last date of assessment in respect of these Assessment Years expired, it vested a valuable right in the assessee which cannot be lightly taken away. As a consequence, sub-section (11) of Section 10 has to be interpreted in the manner which is equitable to both the parties. Therefore, the only way to interpret the same is that by holding that power to extend the time is to be exercised before the normal period of assessment expires. On the aforesaid interpretation, other arguments of Mr. Ganguli lose all significance."
