Fortescue Metals Group's High Court challenge against the mining tax has been adjourned to allow the company to amend its statement of claim.
The case is on hold for one month and will allow FMG to make changes and give the Government time to reply.
Earlier this year FMG said the mining tax challenge would be made on constitutional grounds.
The Queensland Government soon announced plans to join the company in the battle, but other state government's have so far refused to join the action.
After QLD's move to support FMG hospitality, manufacturing, tourism and health union United Voice launched a campaign arguing the challenge was a waste of taxpayer money.
