The petitioner was in possession of a Goods Vehicle bearing Registration No.KLA 2385, for a period of ten days. She submits that she sold it to a third party, under Ext.P1 agreement dated 25-3-1996. Later, by Ext.P4 she has been called upon to pay tax for the said vehicle for the period from 1-4-1997 to 30-6-2005. The petitioner submits that this direction is issued without taking note of the intimation filed by her regarding the sale of the said vehicle. The petitioner appealed against Ext.P4, before the Deputy Transport Commissioner. The said appeal was dismissed by order dated 18-9-2006. So, she has filed Ext.P5 revision, before the Transport Commissioner, the 4th respondent herein. During the pendency of the revision, she has been served with Ext.P6 demand notice, directing her to pay the amount covered by an earlier notice issued on 27-2-2004. This writ petition is filed challenging Ext.P6.
