I just don't see why they needed to challenge the act, it had passed and was doing absolutely no harm to anyone. In fact it made Australia a better place to be in, but for whatever reason the government had they challenged it. They believed it went against the current marriage laws and that meant it was illegal and had to be stopped.
Now this wouldn't of been a problem if the High Court could see that the government was only having a bit of a tantrum because someone found a loop hole in their law. But the High Court didn't see it this way. Instead they decided to rule in favour of the Federal Government and remove the Marriage Equality Act. Now keep in mind that people had been getting married since Saturday and the High Court didn't make a decision until Thursday. This mean we have had almost a week of same sex couples getting married and literally nothing changed. Except nearly 30 couples were able to take a further step in their relationship and decide that they love a certain person enough to get married and commit themselves to each other for the rest of their lives.
So for a brief 6 days Australia (well the ACT) had taken a step forward into becoming an accepting and open country where people can feel safe and secure and most importantly, feel like they belong no matter what.
Now thanks to the Federal Government and it's leader Tony Abbott (who's sister is a lesbian I might add) our country has slipped back even further than when we started.
Same sex marriage is about equality amongst the human race, how can Australia claim to be accepting of all people if we won't even let people of the same gender get married! (And don't get me started on how the Australian government treats refugees)
