It's because you are wrong. She's partisan in the sense that her paid role is to be be a human rights watchdog. Hence, the Human Rights Commission, not the Who Is The Best Government Commission. This is why Labor got a clip for the Malaysia Solution and now this government is under pressure for it's ghastly attempts to punish refugees back to where they came from. It's very simple if you don't want to be pulled up for human rights abuses, don't abuse the very human rights you claimed both pre and post election to be the party of.
Whilst we're on hypocrisy, here is our man of the moment George Brandis on human rights before the election.

If you're wondering why so many people are united in their disgust at this government then hypocrisy, as you say, is a very good place to start. Not only have they ratcheted up the awful inhumane policies of previous governments, they've also gone about limiting our freedoms in every other department too. There's barely a single demographic of Australia they haven't lied to yet, including their own base the IPA libertarians. By even his own conception of human rights George Brandis is incompetent or a liar.
Contempt for the policies of lying politicians and the smearing of a woman doing her job in pointing out the truth are NOT THE SAME THING and you should be ashamed.
