A heated debate on the mining tax was guillotined to force a vote on Monday night and was subjected to two separate opposition motions to suspend standing orders. Independent Senator Nick Xenophon succeeded with a non-binding second reading amendment calling on the government to release its legal advice that the tax is constitutionally sound.
The Mineral Resources Rent Tax (MRRT) Bill 2011 and related bills will now go to the governor-general for royal assent. The government says the tax will help spread the benefits of the mining boom to less successful sectors of the economy. The mining tax is due to come into effect as of July 1.
