However, the petitioner reserves their right to pursue that question in a more appropriate case. They would be now satisfied with a direction to the CESTAT, Bangalore, to dispose of appeal No.E/164/01 expeditiously.

In view of the consensuses of opinion, I dispose of this original petition with a direction to the CESTAT,
