We already knew from the last few years and the introduction of Workchoices and more how having a Government majority in the Senate leads to an undemocratic failure of the Upper House’s role as a House Of Review.
Now we see how having an Opposition majority can also lead to undemocratic obstructionism. The Liberal party, having spun the line that Senate Select Committees were unnecessary throughout their time as in government, used the very first sitting day of the new Parliament to set up three new Select Committees, at least one of which seems to have no other purpose but to delay the introduction of the Labor governments legislation aiming to reform Workchoices.
Other Select Committees may be genuinely useful: Andrew Bartlett has more. I heard Rachel Siewert on the radio expressing her parliamentary disgust with the current Opposition’s cynical opportunism, but I haven’t chased down a transcript of that speech yet.
