According to the petitioner, they are the dealer in airconditioner and textile machinery spares. For the assessment year 1991-92, the first respondent completed the final assessment on 24.03.2000, bringing certain turnovers to tax, besides levying penalty under section 12(5)(iii) of the TNGST Act, 1959. Challenging the said order of assessment, the petitioner preferred a first appeal before the second respondent in AP.No.188/2000, which was partly allowed, by setting aside certain turnovers and remanding the same for fresh consideration by the assessing officer, without deciding the issue relating to penalty, which according to the petitioner, is barred by limitation. Aggrieved over the same, the petitioner preferred a second appeal before the third respondent in TA.No.246 of 2002, which was also partly allowed, by setting aside certain turnovers and remanding the same for fresh consideration, including levy of penalty, by order dated 20.02.2007, which is impugned in this writ petition by the petitioner / assessee.
