“7. We note that in the present case, the SCN was issued on 27.05.2011. On that date, both the tax entries, namely, Commercial or Industrial Construction Service and Works Contract Service, were available in the Finance Act, 1994. The SCN did mention this in the first para itself. However, the proposal for tax demand was specifically made under Commercial or Industrial Construction Service under Section 65 (105) (zzq) of the Finance Act, 1994. In such situation, we note that it cannot be a case of simple mentioning of wrong provisions of law as submitted by the Revenue. Apparently, the tax liability of composite works contract is to be considered under works contract services only as per legal position settled by the Hon'ble Apex Court in M/s L&T Limited. Even in the appeal, the Revenue submitted that the respondent were engaged in construction services liable to tax under tax entry Section 65(105) (xxq). The grievance of the Revenue is with reference to commercial nature of the construction undertaken by the respondent and not on the correct classification of taxable activity.”
