What are the key differences between a Bill introducing a new tax and an amendment reducing or abolishing an existing tax?
The key differences between a Bill introducing a new tax and an amendment reducing or abolishing an existing tax are:

1. Introduction and Recommendation: A Bill making provision for the imposition of a new tax requires a recommendation from the Governor before it can be introduced or moved in either House of the State Legislature. However, a Bill making provision for the reduction or abolition of an existing tax does not need such a recommendation for its introduction or moving.

2. Application to Legislative Councils: A Bill making provisions for any of the specified matters (including introducing a new tax) cannot be introduced in a Legislative Council without a recommendation from the Governor. In contrast, an amendment reducing or abolishing an existing tax does not require such a recommendation for its introduction in a Legislative Council.

3. Passage of Bills: A Bill involving expenditure from the Consolidated Fund of a State (such as one introducing a new tax) cannot be passed by a House of the State Legislature unless the Governor has recommended to that House the consideration of the Bill. This requirement does not apply to amendments reducing or abolishing an existing tax, which can be passed without the Governor's recommendation for consideration.
