The Chamber of Deputies on Friday voted anew on a bill aimed at lowering the excise duty on fuel. This time MPs voted down the proposal, which first passed in the lower house on Wednesday - to the surprise of the ruling coalition. One of its members had inserted changes into the bill that lowered the tax on petrol and diesel across the board rather than just for farmers, which would have negatively impacted the state budget. After another coalition MP on Wednesday, however, challenged the result, arguing his vote had been incorrectly recorded by the electronic system, a new vote was scheduled. The centre-right opposition, which had threatened to petition the Constitutional Court if a new vote was held, walked out of the chamber.
