For all the talk of a double dissolution election, a number of issues still need to fall into place for it to happen on July 2.

Prime Minster Malcolm Turnbull would have to call the election on May 11, the day after the budget is due.

He also wants legislation for the reintroduction of the Australian Building and Construction Commission to be the main double dissolution election trigger as it would likely fail to pass the Senate for a second time.

But Labor senator Sam Dastyari for one does not see how it would be possible to accommodate these two issues given the Senate is not due back until May 10.

However, he confirmed on Sunday Labor would not stand in the way of the budget's money bills which would need to pass to keep the business of government working because a July 2 election would eat into the next financial year.
