Amusement park entertainments duty: concessional rate applied, with refund relief subject to proof against unjust enrichment.

Bombay HC construed the amusement park entertainments duty scheme on its plain language and held that amusement parks were entitled to the concessional mechanism because no exclusion was expressed in the charging provisions. Reading the relevant sections together, it held that duty was nil for the first three years, 3.75% for the 4th and 5th years, and 7.5% from the 6th year onwards. On refund or adjustment of excess duty, the Court held that the proprietor had to prove that the duty burden had not been passed on and that unjust enrichment had not occurred before retaining the benefit of refund.

Issues: (i) Whether amusement parks were entitled to the concessional rate of entertainments duty under the statutory scheme governing amusement parks for the relevant years; (ii) whether the rate of duty for the 4th and 5th years from commencement was 3.75% and for the 6th year onwards 7.5%; and (iii) whether refund or adjustment of excess duty was permissible without the proprietor establishing that the burden had not been passed on and that there was no unjust enrichment.

Issue (i): Whether amusement parks were entitled to the concessional rate of entertainments duty under the statutory scheme governing amusement parks for the relevant years.

Analysis: The statutory definition of amusement park and the charging provisions were read together with the special provision for amusement parks. The legislative text did not exclude amusement parks from the general mechanism in Section 3(2), and the Court declined to read into the provision words that were not there. The taxing statute had to be construed on its plain language, and where the Legislature intended exclusion it would have said so expressly.

Conclusion: The concessional scheme was applicable to amusement parks.

Issue (ii): Whether the rate of duty for the 4th and 5th years from commencement was 3.75% and for the 6th year onwards 7.5%.

Analysis: Reading Section 3(1)(b), Section 3(2), and Section 3(5)(a) and (b) together, the duty on admissions to an amusement park was computed stepwise. For the first three years there was no duty. For the subsequent two years, the concessional rate worked out to 50% of the duty otherwise leviable, which resulted in 3.75%. From the sixth year onwards, the full rate of 7.5% became applicable. This interpretation harmonised the charging provision with the special concession for amusement parks.

Conclusion: The duty rate was 3.75% for the 4th and 5th years and 7.5% from the 6th year onwards.

Issue (iii): Whether refund or adjustment of excess duty was permissible without the proprietor establishing that the burden had not been passed on and that there was no unjust enrichment.

Analysis: The refund provision required repayment of duty paid in excess, but the doctrine against unjust enrichment remained relevant. The burden lay on the proprietor to produce material showing that the incidence had not been passed on to consumers. The Court therefore held that the proprietor must establish the absence of unjust enrichment before claiming or retaining the benefit of refund adjustment.

Conclusion: The burden of proving absence of unjust enrichment lay on the petitioners.

Final Conclusion: The petitions succeeded on the question of the applicable duty structure for amusement parks, but the refund-related relief remained contingent on the petitioners establishing that the duty burden had not been passed on.

Ratio Decidendi: A taxing statute must be construed strictly on its plain language, and no exclusion or additional words can be read into it unless the legislature has expressly provided for them; refund of excess duty is subject to proof that the incidence has not been passed on and that unjust enrichment has not occurred.
