Hard to see the Senate turning around and rejecting/amending this legislation a second time as this hardly qualifies as some great 'constitutional/moral issue' over which the government would resign and call an election. (Which presumably would happen if the Senate and HoC were at loggerheads over some important legislation)

So is this such an unusual move that the G&M feels it merits a story? 

Or is this just the G&M seeing an opportunity to spout its editorial bias?
