Two distinct authorities issued separate demands and penalties for delayed filing of GSTR-3B returns for the same period, resulting in duplication of proceedings and double taxation; the impugned administrative action was held unsustainable and consequently quashed, with the writ petition allowed. The legal points focus on duplication of proceedings as a bar to multiple demands for the same tax period, the resultant double taxation, liability for interest and penalty arising from delayed GSTR-3B filings, and the availability of writ relief to challenge overlapping tax proceedings.
